Overactive bladder (OAB) is considered to be a disorder of the urinary bladder and is defined by the International Continence Society Terminology Committee as "urgency, with or without urge incontinence, usually with frequency and nocturia". There is some preliminary evidence using functional magnetic resonance imaging (fMRI) that the brain response to bladder filling in OAB patients is abnormal. The purpose of this research is to determine whether there are Central Nervous System (CNS) differences in modulating bladder function that contribute to, or are themselves the cause of the symptoms in OAB patients. We further investigated the pharmacological fMRI changes

Resumo: As disfunções do baixo trato urinário estão entre as complicações mais comumente associadas ao diabetes mellitus, e incluem urgência miccional, alterações da freqüência e incontinência urinária, hiperatividade e hipertrofia da bexiga, tornando complexos os procedimentos diagnósticos e terapêuticos. O mediador primário para a contração do músculo liso detrusor é a acetilcolina (Ach), sendo suas ações mediadas, principalmente, pelos receptores muscarínicos do subtipo M3 e M2, principalmente o subtipo M3. O receptor P2X1, ativado pelo trifosfato de adenosina (ATP), também participa da contração do detrusor; porém, com menor importância. Ambos promovem a contração através da mobilização de Ca2+ citosólico, seja pela formação de inositol trifosfato (IP3), seja pelo influxo de Ca2+ extracelular via canais de Ca2+ tipo L. Além destes mecanismos, os receptores M3 podem desencadear resposta contrátil independente da concentração de Ca2+ citosólico, através da sensibilização ao mesmo, a qual ocorre, principalmente, pela ação da enzima Rho-kinase. A despeito de sua grande relevância na contração da bexiga, até o presente, poucos estudos abordaram as alterações na homeostase do Ca2+ celular resultantes do diabetes mellitus. Além disso, a contribuição da uretra para a cistopatia diabética ainda é pouco compreendida e estudada. O objetivo deste trabalho foi investigar as alterações funcionais, morfológicas e moleculares do baixo trato urinário em camundongos C57BL/6 com diabetes induzida por estreptozotocina, bem como compreender o papel da uretra na fisiopatologia desta desordem. Para tanto, realizamos os seguintes experimentos: 1) análise histomorfométrica da bexiga; 2) estudo cistométrico; 3) concentração-resposta ao agonista muscarínico carbacol (na ausência e na presença do Y27632 ou nifedipina), ao agonista purinérgico ?,?-metileno ATP, cloreto de potássio (KCl) e ao cloreto de cálcio (CaCl2), assim como curvas freqüência-resposta à estimulação elétrica (1-32 Hz, 80 V, 10 segundos) em detrusor isolado, e montado em banho para órgão preenchido com solução de Krebs Henseleit; 4) curvas concentração-resposta ao agonista ?1-adrenérgico fenilefrina, bem como de relaxamento ao nitroprussiato de sódio, tadalafil e Bay 41-2272, em anéis de músculo liso de uretra; 6) expressão de RNAm de receptores muscarínicos M2 e M3, purinérgicos P2X1 e canais de Ca2+ tipo L em detrusor. Os animais diabéticos apresentaram aumento do peso da bexiga, da espessura da parede e do volume da mesma em relação aos camundongos controle. A densidade de tecido neural também foi maior no grupo diabético, enquanto nenhuma alteração foi verificada em relação à densidade de músculo liso e de colágeno. O estudo cistométrico revelou aumento da capacidade e complacência da bexiga nos animais diabéticos, assim como maior amplitude das contrações de micção, aumento da freqüência de micção e de contrações involuntárias. Estes ainda exibiram aumento da pressão intravesical pós-miccional, evidenciando uma perda da eficiência da micção. A contratilidade do detrusor isolado de camundongos diabéticos se mostrou maior em resposta ao carbacol, ?,?-metileno ATP, KCl, CaCl2 e estímulo elétrico. Para avaliar o papel dos canais de Ca2+ tipo L e da rho-quinase no aumento da resposta contrátil ao carbacol, realizamos curvas ao carbacol na presença do bloqueador de canal de Ca2+ tipo L, nifedipina (3 nM) ou do inibidor da rho-quinase, Y27632 (1 µM). A pré-incubação com nifedipina preveniu o aumento da contração no grupo diabético, enquanto na presença do Y27632 não houve redução significativa das contrações em ambos os grupos. A expressão de RNAm de receptores M3 foi significativamente maior no grupo diabético em comparação com o grupo controle, enquanto não foram observadas alterações significativas na expressão de receptores M2 e P2X1. Os camundongos diabéticos exibiram aumento significativo da expressão de RNAm de canais de Ca2+ tipo L. As curvas concentração-resposta em músculo liso de uretra revelaram aumento da contração em resposta à fenilefrina e redução do relaxamento ao doador de óxido nítrico (NO), nitroprussiato de sódio (SNP), no grupo diabético. Em suma, nossos dados mostram que o aumento da contração do músculo detrusor em camundongos diabéticos é devido ao aumento do influxo de Ca2+ extracelular através dos canais de Ca2+ tipo L e ao aumento da expressão de receptores muscarínicos M3. Além disso, o aumento da resistência mecânica da uretra resultou em perda da eficiência do esvaziamento da bexiga associada à hiperatividade da mesma
Abstract: Bladder dysfunction is among the most common and incapacitating complications of diabetes mellitus. The diabetes related lower urinary tract symptoms (LUTS) include overactive bladder, incontinence, urgency, frequency increase and bladder hypertrophy. Acethylcholine (ACh) is the main neurotransmitter responsible for the detrusor smooth muscle contraction, acting mainly at the muscarinic M2 and M3 subtypes. P2X1, through ATP stimuli, also contribute to void contractions. Both M3 and P2X1 activation triggers citosolic Ca2+ mobilization by triphosphate inositol (IP3) formation or extracellular Ca2+ influx through L-type Ca2+ channels. Activation of M3 receptors can also elicit contractile response through Ca2+ concentration-independent pathways. Despite the great importance of Ca2+ handling/homeostases to receptor-mediated bladder contractions, its contribution to diabetic cistopathy has been little studied. In addition, the contribution of urethra in diabetic cistopathy remains poorly comprehended. The present study was designed to evaluate the functional, structural and molecular alterations of detrusor and urethral smooth muscles (DSM) in streptozotocin-induced diabetic mice. The following experiments were performed: 1) Hystomorfometric measurements; 2) Cystometric study; 3) Contractile responses to the muscarinic agonist carbachol (in the absence and in the presence of nifedipine or Y27632), purinergic agonist ?,?-methylene ATP, KCl, CaCl2 and electrical field stimulation (EFS, 1-32 Hz, 80 V, 10 sec) in detrusor strips mounted in organ baths containing Krebs-Henseleit solution; 4) Concentration-response curves to the ?1-adrenergic agonist phenylefrine were performed in isolated rings of urethral smooth muscle and relaxant curves to sodium nitroprusside (SNP), tadalafil and Bay 41-2272; 5) Expression of mRNA of muscarinic receptors M3 and M2, purinergic P2X1 receptors and L-type Ca2+ channels in detrusor by real-time RT-PCR. Histomorfometric analysis revealed increased bladder weight, volume and wall thickness. Neural tissue density was also higher in diabetic mice, whereas smooth muscle and collagen density were not modified in both groups. Cistometric study revealed increases in bladder capacity and compliance in diabetic group, as well as higher peak pressure, micturition frequency and frequency of non-void contractions. Diabetic mice exhibited enhanced post-void pressure, indicating a decrease in bladder emptying efficiency. Detrusor contractile responses to carbachol, ?,?-methylene ATP, KCl, CaCl2 and EFS were significantly higher in diabetic mice. In order to evaluate the role of L-type Ca2+ channels and rho-kinase in the detrusor hypercontractility, contraction curves to carbacol were performed in the presence of L-type Ca2+ channel blocker nifedipine (3 nM) or the rho-kinase inhibitor Y27632 (1 µM). Pre-incubation with nifedipine prevented the increased carbachol-induced detrusor contractions seen in the diabetic mice, while Y27632 did not significantly affect the detrusor contractions in both groups. Levels of mRNA of M3 receptor and L-type Ca2+ channels were significantly increased in diabetic animals, while M2 and P2X1 mRNA expression were not modified in both groups. Concentration-response curves in urethral smooth muscle revealed an increased contractile response to phenylefrine, and a reduction on the relaxant responses to nitric oxide donor, sodium nitroprusside (SNP), in diabetic group, indicating an enhanced urethral resistance by diabetes. In conclusion, our data shows that the overactive detrusor in diabetes is likely to be due an increase in extracellular Ca2+ influx through L-type Ca2+ channels and an enhanced M3 muscarinic expression. Moreover, the higher urethral mechanical resistance result in decrease of the bladder emptying efficiency in diabetic mice associated to detrusor overactivity

Resumo: Introdução: A Síndrome da Bexiga Hiperativa (BH) é definida pela ICS (International Continence Society) como urgência urinária, acompanhada ou não por incontinência e frequentemente associada ao aumento da frequência urinária e noctúria. Objetivo: O objetivo do estudo foi verificar a influência da idade, do índice de massa corporal (IMC) e de antecedentes gestacionais nos sintomas de bexiga hiperativa em mulheres no menacme. Pacientes e Métodos: No total foram avaliados os questionários preenchidos por 1052 mulheres com idade entre 20 e 45 anos na região de Campinas. Foi utilizado o questionário ICIQ-OAB, uma ferramenta específica para bexiga hiperativa, em sua versão validada em Português e uma ficha de avaliação para dados demográficos e história médica, incluindo: idade, peso, altura, paridade e via de parto. Resultados: De modo geral, mulheres com idade entre 35 e 45 anos apresentaram escore do ICIQ-OAB significativamente maior do que todos os outros grupos (20 a 22; 23 a 27 e 38 a 34) (p<0.0001). Mulheres multíparas e primíparas apresentaram escore significativamente maior do que as nulíparas (p<0,001); e os sintomas não diferiram de acordo com a via de parto - vaginal ou cesárea (p=0.0074). Não foram encontradas diferenças significativas no escore entre os grupos de IMC (<18,5; 18,8 a 24,9; 25 a 29,9 e ? 30) (p=0,0066). Também foram encontradas diferenças significativas com relação ao incômodo causado pelos sintomas. Mulheres de 35 a 45 anos se sentem mais incomodadas do que os outros grupos com relação á frequência (p<0.0001), noctúria (p=0.0011), urgência (p=0.0015) e incontinência por urgência (p<0.0001). O incômodo causado pelos sintomas não diferiu entre os grupos de mulheres nulíparas, primíparas e multíparas (p=0,9363). As mulheres com IMC entre 25 e 29,9 apresentaram incômodo maior do que aquelas com IMC entre 18,5 e 24,9, com relação à incontinência por urgência (p=0,002). Conclusões: Na população estudada de mulheres no menacme, os sintomas de bexiga hiperativa são encontrados mais frequentemente e causam mais incômodo em mulheres com idade mais avançada, índice de massa corporal mais elevado e com histórico de pelo menos uma gestação
Abstract: Introduction: Overactive Bladder Syndrome (OAB) is defined by the ICS (International Continence Society) as urinary urgency, with or without urgency incontinence and frequently associated with increase of frequency and nocturia. Objectives: The aim of the study was to verify the influence of age, body mass index (BMI) and obstetric history in the symptoms of overactive bladder in premenopausal women. Patients and Methods: We analyzed a total of 1052 questionnaires that were filled out by women aged 20-45 in the area of Campinas, SP. We chose the ICIQ-OAB questionnaire, a tool that is specific for overactive bladder, in its Portuguese validated version and na assessment form with demographics and medical history, that included: age, weight, height, parity and mode of delivery (vaginal or cesarean). Results: Overall, women aged 35-45 presented higher scores than all other age groups (20 - 22; 23 - 27 and 38 - 34) (p<0.0001). Multiparous and primiparous women presented higher scores than nulliparous ones (p<0,001); and the symptoms did not differ according to mode of delivery ¿ vaginal or cesarean (p=0.0074). No significant differences were found between the BMI groups - <18,5; 18,8 - 24,9; 25 - 29,9 and ? 30 - (p=0,0066). We also found differences regarding symptom bother. Women aged 35-45 were more bothered than all other groups regarding frequency (p<0.0001), nocturia (p=0.0011), urgency (p=0.0015) and urgency incontinence (p<0.0001). Symptom bother did not differ between nuliparous, primiparous and multiparous women (p=0,9363). Women with BMI 25 - 29,9 were more bothered by urgency incontinence than those with BMI 18,5 - 24,9 (p=0,002). Conclusions: In the premenopausal women population of this study, OAB symptoms were found more frequently and cause more bother in older women, with higher BMI and with history of at least one pregnancy

Full textOveractive Bladder Syndrome (SBH) is characterized by urinary urgency with or without incontinence, accompanied by frequency and nocturia. Treatment is initially clinical, aimed at relaxing the detrusor muscle with the use of anticholinergics, antispasmodics and antidepressants tricíclinos. Anticholinergics reduce the contractile activity of the detrusor muscle by blocking muscarinic receptors at the neuromuscular junction. Imipramine is a tricyclic antidepressant that has anticholinergic action and alpha-adrenergic indirect, relaxing muscles and increasing detrusor pressure intrauretral, reducing the frequency of urinary leakage, being a good alternative for Urgency Urinary Incontinence (IUU) and mixed urinary incontinence (IUM). OBJECTIVES: To validate Imipramine as an option for patients with SBH and to verify the occurrence and frequency of adverse effects. METHODS: A randomized crossover clinical trial, with women over 18 years with complaints of IUU or IUM treated at the Urogynecology Clinic of Hospital de Clinicas de Porto Alegre (HCPA). For an improvement of 71% in the imipramine group and 16% of perineal exercises, with "p" of 0.05 and a power of 80%, 19 patients are needed in each group (Epi-Info). Totaled an "n" of 38 patients, an estimated 20% loss. RESULTS AND CONCLUSIONS: 38 women were randomized, with 6 patients excluded. 32 patients underwent three months of conservative treatment and three months of use of imipramine. At the end of 6 months was performed statistical analysis. 24 patients maintained their use of medication after the study. There was no difference between groups regarding demographics, comorbidities, medication use, surgery, genital dystopias, presence of side effects with the medication, time of drug discontinuation and urinary loss pressure (VLPP). There was statistical difference in relation to the presence of uninhibited contractions (CNI) during urodynamic evaluation. Regarding the questionnaires, the use of imipramine showed an improvement of 16.8 times over the allocation when compared to a 2.1 times improvement in the conservative treatment. Regarding the General Health Perception (PGS), there was no statistical difference, but in relation to assessing the impact of incontinence (II), there was significant difference in the group treated with imipramine performed. Demonstrated to an improvement in urinary loss of 16, 3 times when compared to the beginning of the allocation. The analysis of the final score showed a statistical significance in the group's interaction with the type of treatment used in a given moment in time. In conclusion, as the only medication available in the Brazilian Public Health System (SUS) to treat this disease that affects a substantial number of women, since it proved to be safe in relation to the side and made statistically significant compared to conservative treatment, we can move to use it with caution, as a therapeutic option for today's most commonly used anticholinergic, oxybutynin. However, it is believed that more trials should be conducted with more patients and perhaps comparing imipramine with oxybutynin, because it is a reference for this pathology.

Full textIntroduction: The investigation of lower urinary tract symptoms usually starts with the history, physical exam and simple clinical tests. However, quite often this investigation is not sufficient for the correct diagnosis of urinary incontinence. In these cases, the urodynamic test is accomplished to confirm it. The best method to evaluate the urodynamic has not been established. In spite of the conventional cystometry being considered as the gold standard and being the most accepted investigative method for detrusor overactivity, the conventional retrograde filling urodynamic method of remains controversial. Since it is a non-physiologic filling, several studies have shown high rates of false negatives concerning the diagnosis of detrusor overactivity. Objective: To estimate the prevalence of detrusor overactivity during ambulatory urodynamic tests in symptomatic patients whose results of conventional urodynamic evaluation were normal. Methodology: The research subjects were women referred to the urogynecology service of Hospital de Clínicas, Porto Alegre, Brazil for further investigation due to urinary incontinence symptoms (overactive bladder syndrome, urge incontinence or mixed incontinence), whose conventional urodynamics results did not show any detrusor overactivity. The sample size was calculated using the WinPEPI program (Programs for Epidemiologists for Windows) 11.43 version and was based on the findings of a pilot study with 6 patients. Using a 95% confidence interval and an estimated urodynamic detrusor overactivity prevalence of 83% with a standard error of 17%, a sample size of 19 patients was obtained. A level of significance of 5% (p≤0.05) was considered. SPSS 21.0 version program was used to accomplish the statistical analysis. Results: A total of 20 women were included in this study. The mean age was 56.1 years, the mean body mass index was 29.7 and the mean time of the symptoms was 5 years. We found mixed urinary incontinence in 18 (90%) and urge incontinence in 2 (10%) patients. All conventional cystometry tests were normal; however, in 14 (70%) patients the ambulatory urodynamics was able to diagnose detrusor overactivity. Conclusion: The ambulatory urodynamics evaluation seems to have a major role in the additional evaluation of more complex cases of urinary tract dysfunctions, when there is a diagnostic and therapeutic flaw – especially in the evaluation of detrusor overactivity. We found 70 % of false negative in the conventional cystometry. However, having in mind the higher cost of the equipment and catheters in relation to the conventional one, more studies are necessary for the incorporation of this test in the Brazilian clinical practice.

Resumo: Objetivo: Avaliar a associação da função muscular do assoalho pélvico (AP) com a presença de sintomas urinários no terceiro trimestre gestacional de nulíparas e em primíparas 60 dias pós-parto. Sujeitos e método: Este é um estudo de coorte prospectivo, com análises tipo corte transversal para a gestação e para o puerpério, apresentadas nesta dissertação. Gestantes entre 30-34 semanas gestacionais de feto único, entre 18-35 anos, que faziam prénatal no CAISM-UNICAMP ou em Unidades Básicas de Saúde de Campinas, foram selecionadas. Gestantes que evoluíram para parto vaginal com episiotomia e cesariana após trabalho de parto foram avaliadas dois meses após o parto. Nos dois momentos estudados, foi registrada a medida da contração do AP por meio de eletromiografia de superfície - EMGs (tônus de base - TB, contração voluntária máxima - CVM e contração sustentada média - CSM), e por graduação de força muscular (graus 0-5). Avaliou-se a presença de sintomas urinários de noctúria, urgência e aumento de frequência urinária diurna (sintomas de Bexiga Hiperativa - BH), enurese, e incontinências de esforço e de urgência por meio de entrevista, na gestação e no pós-parto. Excluíram-se as mulheres com: dificuldade de compreensão, déficit motor/neurológico de membros inferiores, cirurgia pélvica prévia, diabetes, contraindicação para palpação vaginal e que praticavam exercícios para a musculatura do AP. Foram utilizados os testes qui-quadrado e Exato de Fisher para análise de proporções e o teste de Mann-Whitney para analisar diferenças de médias. Foram calculadas as razões de prevalência (RP) com intervalos de confiança (IC) de 95%. Resultados: Foram avaliadas 91 gestantes, em média com 32 semanas gestacionais e 24,3 anos. Os valores médios encontrados de TB, CVM e CSM foram 4,8µV, 19,2µV e 12,9µV, respectivamente e a maior parte das gestantes (48,4%) apresentou grau três de força muscular. O sintoma urinário mais prevalente foi a noctúria (80,2%), seguido do aumento de frequência urinária diurna (59,3%) e da incontinência urinária de esforço (50,5%). Observou-se associação entre a presença de sintomas de BH com menor TB. Não foi observada associação entre a presença de sintomas urinários com a graduação de força, com CVM e CSM. Gestantes da cor branca apresentaram prevalência 1,79 maior de incontinência urinária de esforço (RP bruta=1.79 [IC95% 1,12-2,87]). Entre as 46 puérperas avaliadas (43% submetidas ao parto vaginal e 57% à cesariana), em média 63,7 dias pós-parto, os valores médios encontrados de TB, CVM e CSM foram 3µV, 14,6µV e 10,3µV, respectivamente. A maior parte (56,5%) apresentou grau três de força muscular. Os sintomas mais prevalentes foram a noctúria (19,6%), urgência (13%) e o aumento de frequência urinária diurna (8,7%). Puérperas obesas e com sobrepeso tiveram 4,62 vezes mais sintomas de BH (RP bruta=4,62 [IC95% 1,15-18,5]). A perda urinária aos esforços foi a mais prevalente entre as incontinências, acometendo 6,5% das puérperas. Nenhuma outra característica, incluindo via de parto, associou-se aos sintomas de incontinência ou BH. Não foi observada associação entre a presença de sintomas urinários com os valores de EMGs ou graduação de força. Conclusão: Foi observado menor TB entre gestantes que apresentavam sintomas de BH. Não se observou associação entre as outras medidas de avaliação do AP com os sintomas urinários. Após o parto não se observou associação entre a graduação de força e EMGs do AP com os sintomas urinários
Abstract: Purpose: To evaluate the association between pelvic floor (PF) muscle function and urinary symptoms in the third trimester of pregnancy in nulliparous and primiparous 60 days postpartum. Subjects and method: A prospective cohort was conducted with cross-sectional analysis for pregnancy and the postpartum period presented in this dissertation. Pregnant women between 30-34 weeks of pregnancy of a single fetus, between 18-35 years, from antenatal clinics of UNICAMP-CAISM or from Primary Health Units of Campinas, were selected. Pregnant women who had a vaginal delivery with episiotomy and cesarean section after labor were assessed two months after birth. In both periods studied, PF muscle function was accessed by surface electromyography - sEMG (basic tonus-BT, maximum voluntary contraction-MVC average of sustained contraction- ASC), and by muscle strength grading (grades 0 -5). Were evaluated the presence of urinary symptoms of nocturia, urgency and increased daytime frequency (overactive bladder symptoms - OAB), enuresis, urge and stress urinary incontinence were identified through interview, during pregnancy and postpartum. Women excluded were those with: disability to understand, motor or neurological impairment of lower limb, pelvic surgery, diabetes, contraindication for vaginal palpation and practitioners of exercises for PF muscles. Chi-square and Fisher Exact test were used for analysis of proportions and the Mann-Whitney test to analyze differences in means. Prevalence ratios (PR) were calculated with 95% confidence intervals (CI). Results: Ninety-one pregnant women were evaluated with an average of 32 weeks' pregnancy and 24.3 years. The average values of BT, MVC and ASC were: 4.8µV, 19.2µV and 12.9µV respectively, and most of the women (48.4%) presented muscle strength grade three. The most prevalent urinary symptom was nocturia (80.2%), followed by increased daytime frequency (59.3%) and stress urinary incontinence (50.5%). There was an association between symptoms of OAB with lower BT. There was no association between urinary symptoms and the degree of strength, with MVC e ASC. White pregnant women had a prevalence 1.79 higher of stress urinary incontinence (PR crude = 1.79 [95% CI 1.12 to 2.87]). Among the 46 mothers tested (43% with vaginal deliveries and cesarean sections 57%) on average 63.7 days postpartum, the mean values for BT, MVC and ASC were 3?V, 14.6µV and 10.3µV, respectively. Most women (56.5%) had grade three of muscle strength. The most prevalent symptoms were nocturia (19.6%), urgency (13%) and increased daytime urinary frequency (8.7%). Puerperal obese and overweight had 4.62 times more OAB symptoms (PR crude = 4.62 [95% CI 1.15 to 18.5]). The stress urinary incontinence was the most prevalent incontinence, affecting 6.5% of postpartum women. No other feature, including mode of delivery, was associated with symptoms of incontinence or OAB. There was no association between urinary symptoms and the degree of strength or PF sEMG values. Conclusion: A lower TB was observed among pregnant women with OAB symptoms. No association was observed between other measurement of PF muscle function and urinary symptoms.

Resumo: Estudos clínicos vêm relacionando a síndrome metabólica / obesidade a sintomas do trato urinário inferior, também referidos como LUTS (da sigla Lower Urinary Tract Symptoms), os quais compreendem diversas queixas relacionadas a problemas de armazenamento e/ou esvaziamento da bexiga urinária. Estes sintomas acometem milhares de pessoas em todo o mundo, estando relacionados à frequência, urgência e noctúria, e frequentemente associados à bexiga hiperativa, que pode evoluir para incontinência urinária. O trato urinário inferior (TUI) é composto basicamente pela bexiga e uretra. A dinâmica vesicoesfincteriana compreende duas fases: Fase de armazenamento e Fase de eliminação. Estes processos envolvem uma sincronia de ações do músculo liso detrusor e uretra para um correto ciclo miccional. A despeito dos estudos epidemiológicos apontarem para uma correlação positiva entre síndrome metabólica/obesidade e LUTS, os mecanismos fisiopatológicos envolvidos permanecem pouco compreendidos. Portando, utilizando um modelo animal de obesidade associada à bexiga hiperativa, procuramos analisar as alterações causadas pela obesidade no trato urinário inferior antes e após o tratamento com o ativador da GCs, BAY 60-2770. O BAY 60-2770 faz parte de uma nova classe de drogas, denominadas ativadores da GCs. Essas drogas são capazes de ativar a GCs de maneira independente do NO e/ou grupamento heme, e apresentam uma potência aumentada quando o ferro se encontra em sua forma oxidada (Fe3+). Especificamente, realizamos os seguintes experimentos em camundongos controles e obesos: 1) cistometria; 2) curvas concentração-resposta a diferentes agentes contráteis e relaxantes na bexiga e/ou uretra; 3) determinação dos níveis de GMPc; 4) expressão das subunidades de ?1 e/ou ?1 da GCs; 5) medida das espécies reativas de oxigênio. O camundongo obeso apresentou um padrão miccional irregular caracterizado pelo aumento do número de contrações miccionais e de contrações involuntárias, alterações normalizadas após o tratamento com BAY 60-2770. Na bexiga, o carbacol, KCl e CaCl2 produziram contrações de forma concentração-dependente em tiras isoladas de bexiga, contrações que foram maiores em animais obesos quando comparado aos controles. O tratamento com BAY 60-2770 normalizou as contrações da bexiga em animais obesos. Um aumento de 78% nas espécies reativas de oxigênio foi observado em bexigas de animais obesos, resultado não alterado pelo BAY 60-2770. O tratamento com BAY 60-2770 gerou um aumento de 10 vezes nos níveis de GMPc em bexiga de animais obesos, sem afetar a produção desse nucleotídeo cíclico nos animais controles. A expressão protéica das subunidades ?1 e ?1 da GCs estava 40% diminuída em bexiga de animais obesos, esse resultado foi normalizado após o tratamento com BAY 60-2770. Em uretra, relaxamentos induzidos por NO (nitrito de sódio acidificado), doadores de NO (s-nitrosoglutationa e nitroglicerina) e BAY 41-2272 (estimulador da GCs) se apresentaram reduzidos em obeso quando comparado ao grupo controle. O relaxamento uretral por BAY 60-2770 apresentou um padrão diferente e foi 43% maior em camundongos obesos, resultado acompanhado pelo aumento nos níveis de GMPc. A oxidação da GCs potencializou o relaxamento uretral induzido por BAY 60-2770. O tratamento crônico reverteu completamente as disfunções uretrais dos animais obesos. A produção de espécies reativas de oxigênio estava aumentada e a expressão da subunidade ?1 da GCs diminuída na uretra do animal obeso, ambas as alterações foram revertidas pelo tratamento com BAY 60-2770. Concluímos então que as contrações aumentadas da bexiga e a disfunção no relaxamento uretral estão associadas com a produção de espécies reativas de oxigênio e "downregulation" da sinalização GCs ¿ GMPc. A prevenção da degradação da GCs pelo tratamento crônico com BAY 60-2770 melhora as disfunções miccionais de camundongos obesos. Portanto, o BAY 60-2770 pode ser de grande valor terapêutico no tratamento de complicações urológicas associadas à obesidade
Abstract: Clinical studies have shown an association between metabolic syndrome / obesity and lower urinary tract symptoms (LUTS), name given to a group of symptoms affecting the bladder during urine storage and voiding. These symptoms affect thousands of people throughout the world and are related with frequency, urgency, nocturia and often associated with overactive bladder (OAB), which may result in urinary incontinence. The low urinary tract consists of the bladder and urethra. Vesical sphincter dynamics is divided into two phases: storage and voiding phase. Each phase requires a coordinated interaction between urethra and bladder to allow a healthy urinary function. Despite epidemiological studies suggest a positive correlation between metabolic syndrome / obesity and LUTS, its pathophysiological mechanisms are still poorly studied. Therefore, using an animal model of obesity associated OAB we studied low urinary tract before and after treatment with the sGC activator BAY 60-2770. BAY 60-2770 is a novel class of drugs, classified as soluble guanylyl cyclase (sGC) activators. This class of drugs acts by NO- and heme-independent mechanisms and present a higher potency to oxidated form of sGC heme iron (Fe3+). More specifically we conducted the fallowing experiments: 1) cystomettry; 2) concentration ¿ response curves to contractile and relaxing agents in bladder and/or urethra; 3) determination of cGMP levels; 4) evaluated expressions of ?1 and/or ?1 sGC subunits; 5) measurement of reactive oxygen species. Obese mice displayed an irregular micturition pattern characterized by significant increases in voiding and non-voiding contractions, both of wich were normalized by BAY 60-2770 treatment. In the bladder, carbachol, KCl and CaCl2 produced concentration-dependent contractions in isolated bladder strips that were markedly greater in obese compared with control group. BAY 60-2770 treatment normalized the bladder contractions in obese group. A 78% increase in reactive-oxygen species (ROS) generation in bladder tissues of obese mice was observed, and that was unaffected by BAY 60-2770. Treatment with BAY 60-2770 generated a 10-fold increase in GMPc levels in bladder from obese mice, without affecting this nucleotide level in lean group. Protein expression of ?1 and ?1 subunits of sGC was decreased by 40% in bladder tissues of obese animals, which was restored by BAY 60-2770. In the urethra, relaxations induced by NO (acidified sodium nitrite), NO-donors (S-nitrosolutathione and glyceryl trinitrate) and BAY 41-2272 (sGC stimulator) were markedly reduced in obese compared with control mice. As opposed, urethral relaxations induced by BAY 60-2770 were 43% greater in obese mice, which was accompanied by increases in cGMP levels. Oxidation of sGC with potentiated BAY 60-2770-induced USM responses in control group. Long-term oral BAY 60-2770 administration fully prevented the impairment of urethral relaxations in obese mice. Reactive-oxygen species (ROS) production was enhanced, whereas protein expression of ?1 sGC subunit was reduced in USM from obese mice, both of which were restored by BAY 60-2770 treatment. In conclusion, enhanced bladder contractions and impaired urethral relaxations in obese mice are associated with ROS generation and downregulation of sGC- cGMP signaling. Prevention of sGC degradation by long-term BAY 60-2770 administration ameliorates the micturition dysfunction in obese mice. Therefore, BAY 60-2770 could be of great therapeutic value in the treatment of urological complications associated with obesity

Estimar a prevalência da síndrome de bexiga hiperativa (BH) e de outros sintomas referentes ao trato urinário inferior em uma amostra com base populacional de um grande centro urbano do nordeste brasileiro. Adicionalmente, pretendeu-se avaliar o impacto desses sintomas na qualidade de vida dos participantes, investigar possíveis fatores associados à prevalência de BH e descrever a busca por tratamento para essa síndrome. Métodos: A prevalência de BH foi avaliada segundo sua definição mais recente, estabelecida em 2002 ,pela Sociedade Internacional de Continência (SIC) e o inquérito domiciliar utilizou o método de amostragem estratificado em três estágios, abrangendo 17 regiões administrativas da cidade de Salvador. Os resultados são apresentados de acordo o sexo e a faixa etária. Resultados: Três mil indivíduos com idade ≥ 30 anos foram incluídos no estudo, sendo 1.500 homens e 1.500 mulheres (taxa de resposta de 82,9%). A prevalência de BH foi de 5,1% em homens e 10% em mulheres. Nicturia (≥ 1 por noite) esteve presente em 64,4% dos homens e 71,2% das mulheres, enquanto que a prevalência de nictúria (≥2 por noite) foi de 33,3% e 36,5%, respectivamente. Já a freqüência urinária aumentada foi descrita por 15,4% dos homens e 23,7% das mulheres. A maioria das pessoas com urgência, 80% dos homens e 78% das mulheres, relatou algum grau de desconforto em possuir esse sintoma e indivíduos com BH tiveram alto grau de depressão e ansiedade (p<0,001). Conclusão: Esse é o maior estudo epidemiológico com base populacional no Brasil e que utiliza as novas definições referentes ao trato urinário inferior, recomendadas pela SIC em 2002. O incômodo provocado nos indivíduos, o impacto na qualidade de vida e a prevalência dos sintomas de BH destacam a gravidade dessa síndrome.
To estimate the prevalence of overactive bladder syndrome (OAB) and the other lower urinary tract symptoms (LUTS) in a sample of the big urban center in the Brazilian Northeastern. Additionally, to evaluate the impact of these symptoms in quality of life of participants, to investigate possible factors associates to the prevalence of OAB and to describe help seeking behaviors for urinary problems. Methods: The prevalence of OAB was evaluated according to your more recent definition established in 2002 for the International Continence Society (ICS) and the domiciliary inquiry used a three-step sampling method, enclosing 17 administrative regions of the city of Salvador. The results are presented according to gender and age cohort. Results: A total of three thousand individuals aged ≥ 30 years were analyzed in the study, (1,500 men and 1,500 women) with response rate of 82.9%. The prevalence of BH was 5.1% in men and 10% in women. Nocturia (≥ 1 time/ night) was present in 64.4% of men and 71.2% of the women, while that the prevalence of nocturia (≥ 2 time/ night) was 33.3% and 36.5%, respectively. However the increased frequency was described for 15,4% of men and 23.7% of the women. The majority of the people with urgency, 80% of men and 78% of the women, report any bother with symptom and OAB subjects had high level of depression and anxiety. Conclusion: This is the largest epidemiologic study with population-based in Brazil and that it uses the new definitions of the ICS of 2002. The bother provoked in the individuals, the impact in the quality of life and the prevalence of the LUTS salient the gravity of this syndrome.

Full textThis study aims to analyze the quality of life (QoL) of the women with Overactive Bladder (OAB) according the ICS definition, verify the correlations between the Qol scores and the social, demographics and clinical characteristics of the sample, and verify the correlations between the KHQ scores and the symptoms scale. It was approved by the Ethical Committee and investigated 334 women in the female population that filled out a social, demographic and clinical questionnaire and the King´s Health Questionnaire (KHQ), a specific health related questionnaire to evaluate QOL and symptoms of women with urinary incontinence and OAB. Women with evaluable data were included (33) in this study and it were possible to assess the prevalence of OAB in the city. The interview were made at the women\'s home and the data was organized with the software SPSS version 13.0 and analysed with the Categorical Regression with Optimal Scaling (CATREG) by the stathistical programs GENSTAT for Windows versão 8, Sudaan 7.5 e NCSS 2007. It was evaluated the non parametric correlations between the KHQ domains and the social, demographic and clinical data by the Spearman Rank Correlation, the significances of the Qui-square of the Hosmer-Lemeshow Test ranging from 0,384-0,85 with a good adjustment of the models. The test shows that the contribution of any variables was significant (p<0,05). The psychometric properties were tested using the Cronbach\'s Alpha Coefficient (RL=0,76; PL=0,42; SL=0,82; PR=0,98; E=0,90; SE=0,83 e SM=0,80). The symptoms considered was diurnal urinary frequency, nocturnal frequency, urinary urge incontinence and urgency in this important sequence and the NagelKerk test shows that this characteristics explains 72% of the occurrence ranging of OAB. The KHQ domains with the high scores were UII (49,49), SE (45,95); RL (40,40) and GHP (40,15). The symptoms diurnal frequency, urgency, and urinary urge incontinence had a positive and significant association with the KHQ domains and the urinary urge incontinence was the best one (R2 = 0,631). Diabetes mellitus, high blood pressure, neurological problems, urinary tract infections, pain, perimenopausal symptoms, high age, constipation, pelvic surgery, many deliveries, few sexual relationships, few libido, alcoholic beverages, pepper and caffeine were statistical related with the OAB. The authors concluded that the OAB improves a significant worst in the women\'s HRQoL

Full textINTRODUCTION: The lower urinary tract dysfunction (LUTD) may be due to bladder contractions during the filling phase (detrusor overactivity) or the lack of coordination between bladder contraction and relaxation of the pelvic floor muscles during bladder emptying (voiding dysfunction ). Several publications have suggested benefits of using electromyographic biofeedback (EMG) and parasacral transcutaneous electrical nerve stimulation (TENS) in treating these conditions. However there is a lack of controlled studies comparing these two forms of treatment. OBJECTIVE: To compare the effectiveness of EMG biofeedback and parasacral TENS techniques in children with DTUI. METHODS: A prospective and randomized study with 64 children, 43 girls and 21 boys, mean age 9.39 years. The children were divided into two treatment groups: biofeedback group and parasacral TENS. The criteria for assessing the effectiveness of techniques were the rate of resolution of daytime and nighttime symptoms, improvements in voiding diary, uroflowmetry and questionnaires. (DVSS - Dysfunction voiding symptoms score). We also acessed changes in quality of life (QOL) constipation and number of episodes of lower urinary tract infection (UTI). RESULTS: GB 54.9% of children had complete response in EMG biofeedback group and 60.6% in those treated by parasacral TENS in daytime symptoms (p = 0.483) and 29.6% and 25% in night time respectively (p = 0.461). Regarding the voiding diary, uroflowmetry and DVSS, both groups had statistically significant improvement (p = 0.001), but the QOL showed no difference between groups (p = 0.959 and p = 0.065). In the evaluation of constipation, there was a decrease in EMG biofeedback group 61.3% to 19.4% (p = 0.002) and in parasacral TENS group 33.3% to 6.2% (p = 0.013). No child had UTI after the end of treatment (p <.001). CONCLUSION: EMG biofeedback and the parasacral TENS are effective for treating DTUI. This efficiency translates into improved daytime and nighttime symptoms as well as in the evaluation made by questionnaire and uroflowmetry. Both techniques showed excellent results, although biofeedback required a fewer number of sessions

Full textBACKGROUND: In the treatment of overactive bladder (OAB) electrical stimulation of the tibial nerve is a conservative therapeutically effective, low cost, good adherence of the patients with satisfactory results. There is no consensus in the literature regarding the periodicity and the number of points for the technical implementation. PURPOSE: To compare the efficacy of electrical stimulation of the tibial nerve protocols to physical therapy for neurogenic OAB not. METHODS: blind randomized clinical trial in 138 women suffering from OAB six months or more randomized into five groups: electrodes positioned on one leg sessions with one or two times per week, electrodes positioned on both legs sessions once or twice per week and a control group. The instruments used were: King\'s Health Questionnaire (KHQ), International Consultation on Incontinence Questionnaire - Short Form, Overactive Bladder Questionnaire (OAB-V8), Voiding Diary and a Continuous Assessment Form. RESULTS: The mean age was 61 ( ± 9), and 91% were in the menopause. In the urination two protocol sessions was better than the once a week (p = 0.026). For the symptom of urgency and incontinence once a week had better result (p = 0.046 and p = 0.0001, respectively). In the application nocturia symptom in both legs was more effective (p = 0.005). In relation to quality of life, only the domain \'physical limitations\' KHQ showed a significant difference (p = 0.0411). Conclusion: It is important to identify the most common symptom of OAB to individualize the practice of physical therapy. The form of application of the electrodes and the frequency of treatment should be modified according to the needs of each patient

Full textBlackround: Lower urinary tract dysfunctions are common non-motor symptoms in Parkinson's disease (PD) and include Neurogenic Overactive Bladder Syndrome (NOBS), characterized by urinary urgency, with or without urge incontinence, accompanied by increased urinary frequency and nocturia . Posterior Tibial Nerve Stimulation (PTNS) is one of the treatment modalities available for the treatment of NOBS. Objective: To determine and compare the effects of PTNS treatment in patients with PD and NOBS symptoms and to maintain long-term results (1 and 3 months). Methods: Controlled, randomized, double-blind and compared with placebo clinical trial. The research was carried out with women with PD and symptoms of NOBS at the Hospital de Clínicas de Porto Alegre. For treatment with PTNS at 12 weeks, patients were divided into two groups: PTNS group and PTNS sham/placebo group. The evaluation of the pre- and post-treatment response was through a specific form, questionnaires to evaluate incontinence and quality of life (OVA-V8 and KHQ), and a voiding diary. After the end of the treatment, the results were followed up to evaluate the subjective improvement in 30 and 90 days. Results: The PTNS group presented a decreased nighttime urinary frequency, number of urgency and urinary incontinence episodes, number of incontinence protection, OAB-V8 and 7 domains of KHQ (p<0.001). Although the control group also showed improvement of the symptoms, the ENTP group presented a superior improvement at the end of the treatment in DM, OAB-V8 and most KHQ domains. PTNS was considered an effective treatment for OAB in 93.3%, while 33.3% of those treated with placebo was considered a responder (p=0.002). After 30 and 90 days, 53.3% and 33.31%, respectively, of the ENTP group reported that they maintained better SBHN symptoms. Conclusion: PTNS was an effective treatment for patients with PD and NOBS. Our hypothesis of clinical superiority of the ENTP group was confirmed and the subjective improvement was considered positive, even if partially at 30 and 90 days after the end of the treatment.!

Full textINTRODUCTION: Overactive Bladder is a syndrome with a high prevalence that negatively affects women\'s quality of life. The clinical symptoms are manifested as urinary urgency, with or without urgency incontinence, frequency and nocturia. The diagnosis is defined based on the clinical symptoms, and the voiding diary is a good assessment. The physiotherapeutic treatment of OAB has as treatment\'s options the transcutaneous tibial nerve electrical stimulation or vaginal electrical stimulation. OBJECTIVE: to verify if the addition of vaginal electrical stimulation to transcutaneous tibial nerve electrical stimulation is more effective than only the electrical stimulation in the tibial nerve for the treatment of women with OAB. METHOD: Randomized controlled trial with 106 women over 18 years old with a diagnosis of overactive bladder or mixed urinary incontinence with predominance of overactive bladder symptoms. The patients were distributed into two groups: Group 1: transcutaneous tibial nerve electrical stimulation (n = 52) and Group 2: vaginal electrical stimulation plus transcutaneous tibial nerve electrical stimulation (n = 54). Both groups received instructions about behavioral therapy. The assessments used were: Three-day voiding diary, functional evaluation of pelvic floor, King\'s Health Questionnaire and Overactive Bladder Questionnaire, all of them applied by a blind evaluator, before and after 12-week treatment, once a week. The primary outcome was urinary frequency in 24 hours. Secondaries outcomes were other overactive bladder symptoms, impact in quality of life, and pelvic floor functionality. RESULTS: urinary frequency in group 2 decreased 1.5 times in relation to group 1. However, this result was not clinically relevant since it was less than 3 mictions. The other variables of voiding diary and impact on quality of life did not present differences between groups. CONCLUSION: The addition of vaginal electrical stimulation to transcutaneous tibial nerve electrical stimulation did not present more effective results in the improvement of symptoms or quality of life in patients with overactive bladder

Full textINTRODUCTION: The overactive bladder syndrome (OAB) is a lower urinary tract pathology that negatively affects the quality of life (QOL) of women whose main symptom is your definition for urinary urgency, with or without incontinence usually accompanied by urinary frequency and nocturia in the absence of metabolic, infectious or local. The diagnosis of BH is defined from the clinical symptoms, but the voiding diary and urodynamic studies are good tools for objective evaluation of this pathology. There are several forms of treatment for OAB, are the main pharmacological and physical therapy, physical therapy has been being considered an important option in a clinical setting. OBJECTIVES: to do a systematic review article about physical therapy in the treatment of female miccional urgency, to evaluate and compare the effects, discomfort and improvement in quality of life (QOL) of vaginal electrostimulation and percutaneous tibial nerve stimulation (PTNS) in women with overactive bladder. METHODS: We conducted a comparative, prospective, randomized trial of physiotherapy in the sector of the Hospital Materno Infantil (HMI) in Goiânia-GO, from march 2010 to august 2011. We randomized 40 women with urodynamic diagnosis of detrusor overactivity, mixed incontinence with predominant symptoms of overactive bladder or urinary urgency only in two groups: vaginal electrical stimulation (n=20) and PTNS (n=20), being held 10 sessions in each group. We used urodynamic studies, voiding diary and QoL questionnaire of King's Health Questionnaire (KHQ) before and after the two procedures, and then visual analog scale. Statistical analysis used: Fisher exact tests, chi quadratic, U Mann Whitney and Wilcoxon tests with a significance level of 0.05. RESULTS: In voiding diary was a reduction in urinary frequency, urge incontinence, nocturia and urgency in both groups. The urgency was present in all women and disappeared in 90% in the PTNS group (p<0.001) and 80% in vaginal electrical stimulation (p<0.001). According to urodynamic evaluation, the group of vaginal electrostimulation showed disappearance of detrusor overactivity in 60% (p=0.005) and PTNS in 75% (p= 0.002). The urodynamics showed significant differences in some parameters analyzed within each specific group and to compare the two groups was not observed differences. The scale and the KHQ domains of the two procedures had similar results as physical therapy to improve QOL, but no significant difference between them. In relation to the discomfort of procedures, PTNS in 80% of women reported no discomfort and 80% reported vaginal electrostimulation mild to moderate discomfort (p<0.001). CONCLUSION: There was no significant difference in the effects and QOL between the vaginal electrical stimulation and PTNS. The PTNS promoted less discomfort for women.
INTRODUÇÃO: A síndrome de bexiga hiperativa (BH) é uma patologia do trato urinário inferior que afeta negativamente a qualidade de vida (QV) das mulheres, cujo principal sintoma para a sua definição é a urgência miccional, com ou sem incontinência, geralmente acompanhada por polaciúria e noctúria, na ausência de fatores metabólicos, infecciosos ou locais. O diagnóstico da BH é definido a partir dos sintomas clínicos, porém o estudo urodinâmico e o diário miccional são bons instrumentos de avaliação objetiva dessa patologia. Existem diversas formas de tratamento para a BH, os principais são o farmacológico e a fisioterapia, uma vez que a fisioterapia vem sendo considerada como uma opção de relevância no meio clínico. OBJETIVO: Fazer um artigo de revisão sistemática sobre a atuação da fisioterapia no tratamento da urgência miccional feminina, avaliar e comparar os efeitos, o desconforto e a melhoria na qualidade de vida (QV) da eletroestimulação vaginal e da eletroestimulação transcutânea do nervo tibial posterior (PTNS) em mulheres com bexiga hiperativa. MÉTODOS: Foi realizado um estudo comparativo, prospectivo e randomizado no setor de fisioterapia do Hospital Materno Infantil (HMI) de Goiânia-GO, no período de março 2010 a agosto de 2011. Foram randomizadas 40 mulheres com o diagnóstico urodinâmico de hiperatividade do detrusor, incontinência urinária mista com predomínio dos sintomas de bexiga hiperativa ou apenas urgência miccional em dois grupos: eletroestimulação vaginal (n=20) e PTNS (n=20), sendo realizado 10 sessões em cada grupo. Foram utilizados o estudo urodinâmico, diário miccional e o questionário de QV King s Health Questionnaire (KHQ) antes e após os dois procedimentos, e posteriormente a escala visual analógica. Para análise estatística utilizou-se: os testes Exato de Fisher, Qui Quadrad, u Mann Whitney e Wilcoxon com nível de significância de 0,05. RESULTADOS: No diário miccional houve a redução da frequência miccional, urgeincontinência, noctúria e urgência nos dois grupos. A urgência estava presente em todas as mulheres e desapareceu em 90% no grupo PTNS (p<0,001) e 80% na eletroestimulação vaginal (p<0,001). Conforme avaliação urodinâmica, o grupo da eletroestimulação vaginal apresentou desaparecimento da hiperatividade detrusora em 60% (p=0,005) e na PTNS 75% (p=0,002). A urodinâmica demonstrou diferença significante em alguns parâmetros analisados dentro de cada grupo específico e ao comparar os dois grupos não foi constatado diferenças. Quanto à escala e os domínios do KHQ os dois procedimentos da fisioterapia apresentaram resultados similares quanto à melhora da QV, mas sem diferença significativa entre eles. Em relação ao desconforto dos procedimentos, na PTNS 80% das mulheres relataram ausência de desconforto e na eletroestimulação vaginal 80% relataram desconforto leve a moderado (p<0,001). CONCLUSÃO: não houve diferença significativa nos efeitos e na QV entre a eletroestimulação vaginal e a PTNS. A PTNS promoveu menos desconforto para as mulheres.

Full textObjective: Non-inhibited contractions (NIC) are present in about 50% of patients with bladder outlet obstruction (BOO) due to benign prostatic hyperplasia (BPH) and 30% of cases persist after surgery. To date, no clinical characteristic can predict accurately which patients are going to improve. We analyzed the role of six detrusor molecular markers in the resolution of NIC after transurethral resection of the prostate (TURP). Methods: We performed a prospective and controlled analysis of 43 patients with BOO due to BPH who underwent TURP from 2011 to 2012. The control group comprised 10 bladder specimens from patients younger than 60 years who underwent radical prostatectomy with an IPSS < 8 and prostate volume < 30 grams. All patients underwent urodynamic analysis pre and post operatively after 6 months. We analyzed the presence, time to occurrence (first vs second half of the filling phase) and grade (40 cmH2O) of NIC as well as its resolution after 6 months of surgery. A biopsy of the bladder muscle was performed at the end of TURP for analysis of nerve growth factor receptor (NGFr), nerve growth factor (NGF), vascular endothelial growth factor (VEGF), endoglin (CD105), muscarinic cholinergic receptor 2 (CHRM2) and muscarinic cholinergic receptor 3 (CHRM3) genes expression. For this purpose, we used the quantitative real time polymerase chain reaction method (qRT-PCR). Results: Mean patient age was 63 years (50 to 75). NIC were present in 21 (48.8%) patients. According to pre-operative measures, NGF gene expression was 3.3 times greater in patients who presented early NIC as compared to those who presented late contractions (p=0.047). The presence or grade of NIC failed to present statistical correlations with the genes. With regard to the outcome, CHRM2 expression was 2.0 times greater among patients who presented resolution of NIC (p=0.072). After 6 months of TURP, 77,8% of patients with DO resolution had increased expression of CHRM2 and CHRM3 genes compared with others cases (p=0,030). Additionally, patients younger than 60 years obtained a 5.0 times more likely to evolve with improved NIC (p=0,056). Conclusion: Neural pathways seem to be more important in the time to NIC occurrence during the filling phase. Muscarinic cholinergic receptors seem to have a prognostic value in the resolution of NIC after surgery. Analysis of greater number of patients is necessary to confirm these results

Resumo: Objetivos: Avaliar em mulheres com doença de Parkinson e disfunções urinárias as correlações dos sintomas urinários com os sintomas motores e disfunções mentais. Verificar a prevalência de hiper-reflexia detrusora (HD), bem como analisar em longo prazo a gravidade do desempenho motor, estadiamento de Hoenh-Yahr, habilidades funcionais, funções neuropsicológicas e a magnitude da progressão desses aspectos clínicos e do declínio cognitivo em pacientes com HD. Sujeitos e Métodos: Estudamos uma coorte ambulatorial de sessenta e três (63) pacientes com DP cujos aspectos neurológicos foram avaliados com a utilização das escalas Unified Parkinson's Disease Rating Scale (UPDRS) e a escala de Hoehn-Yahr. As habilidades funcionais foram avaliadas pela escala Schwab & England e a função urológica foi quantificada pela International Prostatic Symptom Scale (IPSS) e qualificada pelo estudo urodinâmico. Foram então categorizados dois grupos: pacientes com e sem HD. Após sete anos os mesmos parâmetros foram reavaliados e a escala Montreal Cognitive Assessment (MoCA)-versão brasileira foi utilizada para o rastreamento neuropsicológico. Resultados: Na avaliação inicial foi constatada correlação positiva entre os sintomas urinários e a gravidade da doença, porém não havia correlação entre a sintomatologia urinária e os sintomas mentais. Sintomas motores, estágio de gravidade da doença e habilidades funcionais eram mais graves em pacientes com HD. Na reavaliação, os grupos não apresentavam diferença quanto à magnitude da progressão dos sintomas motores, do estadiamento da doença e das inabilidades funcionais. Foi observado no grupo com HD maior declínio cognitivo e uma nítida progressão dos escores mentais com risco aumentado para demência. Conclusão: Hiper-reflexia detrusora é um achado urodinâmico frequente em mulheres com DP e embora esteja associada à pior desempenho motor, estágios de maior gravidade da doença e inabilidades funcionais, não é um fator de maior progressão desses aspectos clínicos. Por outro lado as pacientes com HD tiveram, em longa duração, significante progressão da sintomatologia neuropsicológica.O perfil do declínio cognitivo e o risco para demência necessitam ser confirmados em estudos posteriores
Abstract: Objectives: This long-term study in women with Parkinson's disease (PD) and lower urinary tract dysfunctions aimed to verify the correlation of urinary symptoms with the severity of the disease and mental functions. Verify the prevalence of detrusor hiper-reflexia (DH) and analyze the severity of motor symptoms, Hoehn and Yahr stage, functional abilities and neuropsychological functions, as well as analyze the progression of these clinical aspects and cognitive decline in patients with DH. Subjects and Methods: We studied a cohort of sixty-three (63) PD patients whose neurological aspects were evaluated with the Unified Parkinson's Disease Rating Scale (UPDRS) and Hoehn-Yahr scale. Functional abilities were evaluated by Schwab and England scale and the urological function was quantified by International Prostatic Symptom Scale (IPSS) and qualified by urodynamic study. Two groups were then categorized: patients with and without HD. After seven years the same parameters were re-evaluated and the cognitive functions were assessed with the Montreal Cognitive Assessment (MoCA). Results: At baseline a correlation between urinary symptoms and motor dysfunction was verified but no correlation between urinary symptoms and mental symptoms was observed. The severity of motor symptoms, stage of the disease and functional disabilities were significant in patients with DH. In the follow up, the groups were similar in regards to progression of motor symptoms, Hoehn and Yahr stage and functional disabilities. On the other hand, decline in cognitive function and clear progression of mental scores and risk for dementia was observed in the group with DH. Conclusion: Urinary symptoms are correlated with the severity of the Parkinson's disease. Detrusor hyper-reflexia is a frequent urodynamic finding in women with DP and although it is associated with worse motor performance, stage of the disease and functional disabilities, it is not a factor of greater progression of these clinical aspects of the disease. On the other hand, patients with DH had a significant progression of the neuropsychological symptoms and risk of dementia. The profile of cognitive decline and dementia risk need to be confirmed in subsequent prospective studies

Full textEven if it involves alternating between a filling phase and an emptying phase, the normal micturition cycle cannot be summed up as a binary operation but involves the constant consideration of multiple factors: the filling level of the bladder reservoir, the safety of the environment in which we live, the emotional context in which we evolve and the social constraints to which we are subjected.We now know that there are alterations and/or modifications in brain activity and connectivity, as well as changes in the regulation of the autonomic nervous system, in certain types of lower urinary tract dysfunction - notably in overactive bladder or urge urinary incontinence and in certain types of voiding dysfunctions. Among the therapies available today, electrical modulation/stimulation therapies (tibial neurostimulation and sacral neuromodulation) appear able to normalize and/or modify brain activity and connectivity, as well as ANS balance. They could thus provide at least a partial response to some of the etiopathogenies underlying these lower urinary tract dysfunctions. However, the deployment and positioning of these electrical modulation/stimulation therapies are still limited by an incomplete understanding of their mechanisms of action, imperfect identification of the indications and populations most likely to benefit from these therapies, a lack of consensus on the setting of the electrical current delivered, and a lack of medium and long-term evaluation. In the first part, we questioned the indications for these therapies, and particularly their place as a preventive approach for lower urinary tract dysfunctions due to spinal cord injury. We also questioned the relation, in terms of efficacy, between transcutaneous tibial neurostimulation and sacral neuromodulation, to better support patients in shared medical decision-making processe. Finally, we developed the first tool to predict the success of sacral neuromodulation as a treatment for voiding dysfunction. In the second part, we questioned the mechanisms of action, and more specifically the changes in the balance of the autonomic nervous system in response to an acute S3 sacral root stimulation.In the third part, we questioned the mid-term follow-up (5 years) after definitive implantation of sacral neuromodulation in a geographic population pool, looking for risk factors for discontinuation of follow-up. These data, although still to be supplemented by future research projects, will enable us to further optimize electrical modulation/stimulation therapies in the management of neurogenic and non-neurogenic lower urinary tract dysfunctions

Summary Background The International Continence Society (ICS) in 2002 derived a consensus for symptomatic definition of overactive bladder (OAB) as urinary urgency, with or without urge incontinence, usually with urinary frequency (voiding eight or more times in a 24-hour period), and nocturia (awakening two or more times at night to void), in the absence of pathologic or metabolic factors that would explain these symptoms (Abrams, 2002). OAB occurs in an estimated 17% of the population, and the frequency increases with age in the United States (Stewart, 2003)and 18.6% in Taiwan (Chen, 2003). In European countries, the overall prevalence of OAB symptoms in individuals aged 40 years and more was 16.6%. The prevalence of OAB is similar to or higher than the rates of most other chronic diseases, including asthma, coronary-artery disease, and peptic-ulcer disease (Milsom, 2001). The potential risk factors that might predispose women to the occurrence of OAB were elderly, menopausal, vaginal deliveries, higher BMIs (≧75 percentile), parities >2, symptoms of uterovaginal prolapse, a history of diabetes or hypertension (Chen, 2003; Teleman, 2004). Overall, the effects of OAB on quality of life are profound (Stewart, 2003), but many affected individuals do not seek help from professionals (Milsom, 2001). In the aspect of lower urinary tract symptoms, the symptoms of OAB impair quality of life much more than the symptoms of stress urinary incontinence. The reason is the unpredictable nature of the urinary symptoms associated with detrusor instability (Kelleher, 1997). Patients with symptoms of OAB tend to curtail their participation in social activities and to isolate themselves and are predisposed to depression (Dugan, 2000). Nocturia is associated with sleep disruption, which decreases the quality of life. Postmenopausal women with urge incontinence have a substantially higher risk of falling and sustaining a fracture than women without urge incontinence (Brown, 2000). People with OAB have a greater risk of being injured in a fall (Wagner, 2002). Besides, nocturia is also a risk factor for falls in the elderly (Stewart, 1992). Nocturia also makes the hypertension poor control. The pathophysiology of OAB is very complicated. The common view is that in OAB which is stimulated by acetylcholine released from activated cholinergic (parasympathetic) nerves and this phenomenon may make patient suffer from urgency, frequency and nocturia (Chapple, 2000). OAB is associated with the effects on neurologic control or myogenic activity by a variety of conditions, including : (1) Neurologic illness or injury, most commonly spinal cord injury, stroke, Parkinson disease, Alzheimer disease, diabetes, spinal stenosis, and multiple sclerosis and similar demyelinating diseases; (2) Bladder outlet obstruction that affects sensory and motor aspects of voiding reflexes and leads to changes in bladder muscle structure and function; (3) Urethral weakness associated with intrinsic sphincter deficiency and pelvic relaxation in middle-aged and elderly women; (4) Detrusor hyperactivity and impaired contractility in elderly patients; (5) Emergence of new voiding reflexes mediated by unmyelinated capsaicin-sensitive C-afferents, leading to hypersensitivity-induced overactivity; and (6) So-called idiopathic bladder overactivity, which may be caused by some parts of all these categories or factors not yet discovered(Staskin, 2002). Currently, it is difficult to consolidate our knowledge about OAB and its causes into a single theory. There are simply too many observations that do not easily fit together. It has also been difficult to integrate experimental results on changes in bladder muscle with changes seen in afferent nerve activity after bladder outlet obstruction. Although these changes may occur concurrently in humans and other animals, it is not clear how to integrate our knowledge about them. Additional research into the etiology of OAB is needed. The treatment of OAB includes behavioral treatment, pelvic floor muscle rehabilitation, biofeedback treatment, pharmacologic treatment, neurostimulatory, or surgical modalities. Pelvic floor muscle rehabilitation focuses more on altering the physiologic responses of the bladder and pelvic floor muscles. Biofeedback can help patients learn to inhibit bladder contraction using pelvic floor muscle contraction and other urge suppression strategies (Rovner, 2002). The first-line pharmacological treatment of OAB has been and still is antimuscarinic (anticholinergic) drugs (Andersson, 2004). There is much evidence that the treatment is associated with side-effects that limit its clinical use because of widespread of many types of muscarinic receptor over the whole body. A recent meta-analysis of randomized controlled trials on antimuscarinic treatment (Tolterodine) of OAB concluded that the drugs produce significant improvements in OAB symptoms compared with placebo (Chapple, 2005). Due to its high selectivity to bladder and less side effect of dry mouth and constipation, Tolterodine has become the first choice for patient with OAB. However, in normal physiological state, there is a massive release of acetylcholine during voiding phase of bladder contraction. Does Tolterodine inhibit detrusor contraction during voiding phase of bladder which induces voiding dysfunction due to hypoactive detrusor and increases residual urine amount or decreases urinary flow rate? This study was to evaluate effects of antimuscarinic drug on lower urinary tract function by urodynamic assessment in female patients with OAB, especially focused on detrusor function and residual urine amount. Women with OAB symptoms can show variable findings on filling cystometry. The bladder may show unstable phasic contractions (of any amplitude) that cannot be suppressed (detrusor instability), a tonic rise in bladder pressure (reduced bladder compliance), or a stable but low capacity as a result of pain or urgency (Dwyer, 2002). In clinical observation, some patients with OAB revealed voiding dysfunction in the urodynamic study. The definition of voiding dysfunction is maximal flow rate < 15 ml/sec or post void residual > 150ml (Stanton, 1983; Dwyer, 1994; Everaert, 2000). We also want to know whether the voiding function will deteriorate or not after antimuscarinic drug treatment in these OAB with voiding dysfunction patients. Material and methods We planned to collect at least 30 subjects with OAB from our urogynecology outpatient department. After urodynamic study and pad test screening, subject will be prescribed Tolterodine 2mg 1# BID for six months continuously. After six-month treatment, each subject will perform urodynamic study and pad test again. Paired t-test will be used to evaluate whether there is statistical difference between pre- and post-treatment urodynamic variables by computer statistical soft ware (Stata, 8th version). A p value < 0.05 was considered statistically significant. Results There were forty-four patients enrolled in this study. Three patients (6.9%) dropped out of the study due to side effect (dry mouth). Four patients (9%) lost follow-up. Four patients (9%) completed the six-month treatment but did not undergo the second urodynamic study. Totally thirty-three (70%) women who completed the six-month treatment were evaluated before and after treatment. The average age was 51.9 yeas old. Seventeen (51.5%) patients were menopausal. Among 33 patients, the urodynamic reports of the 30 patients revealed low capacity and hypersensitive bladder. The urodynamic reports of the remaining 3 patients revealed detrusor instability or idiopathic detrusor overactivity (Abrams, 2002). No patient had low compliance bladder. Besides, maximal flow rate in 12 patients with OAB was smaller than 15 ml/sec. They were OAB with voiding dysfunction patients. Among the 12 patients, the urodynamic reports of 11 patients showed hypersensitive bladder with voiding dysfunction and remaining one patient showed idiopathic detrusor overactivity with voiding dysfunction. The average age of this group was 54.3 years old. In total 33 patients, the amounts of first-sensation, first-desire, strong-desire and urgency showed statistically significant increases after Tolterodine treatment. Detrusor pressure at maximal flow rate, maximal flow rate, average flow rate and voiding time showed no statistically significant differences. The residual urine amount had statistically significant increase after treatment but the average amount was within normal range and had no clinical significance. The pad weight results had statistically significant decrease but had no clinical significance. Besides, the 12 patients with OAB and voiding dysfunction revealed the similar results mentioned above. Discussion The side effects of antimuscarinic drug should be notified to patients due to some patients could not tolerate it. According to our study, antimuscarinic drug is effective to distend bladder volume in hypersensitive bladder patients and to stabilize detrusor activity in patients with detrusor overactivity. The parameters of voiding function except post void residual showed no statistical difference in total 33 patients. However, post void residual just increased from the average amount of 38 ml to 56.5 ml. Clinically, post void residual around 50 ml is normal. Post void residual larger than 100 ml is just a suspicious voiding problem. Detrusor pressure at maximal flow rate decreased from average pressure of 32.1 cmH2O to 29.8 cmH2O but was still within normal limit. These data revealed that Tolterodine treatment for patients with OAB is safe and effective. The storage parameters revealed statistically significant increase which means Tolterodine treatment could enlarge bladder capacity and relieved the frequency and urgency symptoms of OAB. The continent parameters except functional profile length did not show statistical change after treatment. The fact that muscarinic receptors distributed not only bladder but also urethra could explain this effect (Mutoh, 1997). Patients with OAB and voiding dysfunction treated with Tolterodine still could benefit from the increase of bladder capacity and stability of detrusor muscle, but the low maximal flow rate still kept the same condition. However, we need a study of larger sample size to support this point.

This is a case of a 41 years old patient, with multiple sclerosis, presenting a three years old history of episodes of urinary urgency incontinence, nocturia, frequency and fecal and gas incontinence. Both the history and the results of the complementary diagnostics tests suggested the diagnosis of neurogenic overactive bladder with fecal and gas incontinence. The first aproach consisted of behavioral therapy and pharmacotherapy with anticholinergics. Due to the failure of the initial therapy she was proposed for sacral neuromodulation. After a four weeks phase test, she presented a significant improvement, having indication to implant the definitive device. At the moment, she has the device for seven months, and presents an improvement of all the initial symptoms: the frequency was reduced to half, with no episodes of urinary incontinence, nocturia, or fecal and gas incontinence. The patient mentioned pain at the site of the device implantation, wich is one of the complications of the procedure.

Full textIntrodução: A neuromodulação sagrada consiste numa técnica aprovada como opção terapêutica para o síndrome de bexiga hiperativa e para a retenção urinária crónica não obstrutiva, na abordagem dos doentes refratários ao tratamento conservador. É fundamental avaliar o seu papel pela influência destas patologias na qualidade de vida dos doentes. O objetivo do presente estudo é analisar os resultados deste procedimento no Serviço de Urologia e Transplantação Renal do Centro Hospitalar e Universitário de Coimbra. Métodos: Realizámos uma revisão retrospetiva dos doentes com síndrome de bexiga hiperativa e/ou retenção urinária crónica, submetidos à implantação de neuroestimulador InterStim II®, entre Outubro de 2013 e Maio de 2018, através da consulta dos processos únicos. No caso dos padrões mistos, optámos por considerar a patologia mais predominante. Efetuámos entrevistas telefónicas, para avaliação da resposta clínica, baseada no grau de satisfação e nos sintomas descritos pelos doentes. Resultados: Numa amostra de 25 doentes, as mulheres e os mais jovens referiram estar mais satisfeitos com o procedimento (p=0,025 e p=0,020, respetivamente). Nos 12 doentes com padrão de hiperatividade, os mais satisfeitos foram os que mais reduziram a utilização de pensos (p=0,038) e os que utilizavam menos pensos diários após a neuromodulação (p=0,051). Nos 13 doentes com padrão de retenção, verificou-se uma diminuição tanto do número de algaliados crónicos, como do número médio de cateterismos vesicais intermitentes, não se tendo encontrado uma correlação com o grau de satisfação. Os padrões retencionistas desenvolveram mais infeções do trato urinário após a técnica (p=0,040). Discussão e Conclusão: Este estudo demonstrou que a neuromodulação sagrada é uma alternativa eficaz à toxina botulínica como terapêutica da bexiga hiperativa, tratando-se de um tratamento por vezes definitivo e com benefícios associados, nomeadamente em disfunções urinárias mistas e coloproctológicas. Confirmou-se que o registo de perdas continua a ser um método útil para a avaliação da técnica, uma vez que os doentes mais satisfeitos com hiperatividade foram aqueles que mais reduziram o número de pensos. No caso das retenções, conclui-se que a técnica foi eficaz, pela redução do número de algaliados crónicos e de cateterismos vesicais intermitentes. Resta, no entanto, salientar a heterogeneidade e as reduzidas dimensões desta amostra, assim como a ausência de um método mais objetivo de avaliação de eficácia da técnica.
Introduction: Sacral neuromodulation is a technique approved as a therapeutic option for overactive bladder syndrome and chronic nonobstructive urinary retention, in the approach for refractory conservative treatment. It is essential the assessment of its role because of the significant influence of these disorders on patients' quality of life. The aim of this study is to analyze the results obtained from this procedure in the Urology and Kidney Transplant Department in the University Hospital of Coimbra, Portugal. Methods: We performed a retrospective review of the patients with overactive bladder and chronic urinary retention, undergone the InterStim II® neurostimulator implantation, from October 2013 to May 2018, through the clinical data described in the medical records. In mixed pattern cases, we chose to contemplate the most predominant pathology. We also performed telephone interviews in order to evaluate the clinical response, based on the level of satisfaction and on the patients’ description of the symptoms. Results: In a sample of 25 patients, women and younger patients reported being more satisfied with the procedure (p=0.025 and p=0.020, respectively). In the 12 patients group with hyperactivity pattern, the most satisfied were those who most reduced the use of pads (p=0,038) and who used fewer daily pads after neuromodulation (p=0,051). In the 13 patients group with a retention pattern, there was a decrease both in the number of long-term urinary catheter users and in the mean number of intermittent urinary catheterization, and no correlation was found with the level of satisfaction. Retention patterns developed more urinary tract infections after the technique (p = 0.040). Discussion and Conclusion: This study demonstrated that neuromodulation is an effective alternative to botulinum toxin as a treatment for overactive bladder. It is a treatment that is sometimes definitive and has associated benefits, especially in mixed urinary and coloproctological disorders. It was confirmed that voiding diaries remain a useful method for the evaluation of the technique, since the most satisfied patients with hyperactivity pattern were those who most reduced the number of pads. In the case of retention patterns, we concluded that the technique was efficient by the reduction of the number of long-term urinary catheter users and of the mean number of intermittent urinary catheterizations. However, it is important to note the heterogeneity and the small size of this population, as well as the lack of a more objective method of assessing technique’s efficiency.
