Abstract:
Dissertação de Mestrado Integrado em Medicina Veterinária<br>A incidência da litíase renal e ureteral em gatos tem vindo a aumentar significativamente, estando intimamente relacionada com a presença de lesões renais crónicas e irreversíveis. O presente estudo pretende demonstrar a verdadeira expressão da litíase renal numa população de gatos com sinais ecográficos de nefropatia crónica que compareceram à consulta no HVA, independentemente da sua situação clínica, avaliar a relação da nefrolitíase e ureterolitíase com a DRC e demonstrar a importância do exame ecográfico na identificação de alte

Abstract:
No tratamento do cálculo coraliforme por nefrolititomia percutânea, há cirurgias com poucas dificuldades e pacientes que evoluem sem complicações, como há casos muito difíceis, com pós-operatório extremamente complicado. O objetivo deste estudo é analisar os fatores de risco pré, intra e pós-operatórios, relacionados com complicações e insucessos da nefrolitotomia percutânea no tratamento do cálculo coraliforme. Foram estudados 57 pacientes portadores de 72 cálculos coraliformes. Houve correlação estatisticamente significante entre complicação e os seguintes fatores: infecção do trato urinário

Introdução: A eficácia da litotripsia extracorpórea por ondas de choque (LECO) no tratamento de cálculos em cálice inferior do rim ainda é motivo de controvérsia. Variáveis que possam impactar nos resultados da LECO ainda não estão bem estabelecidos. Objetivo: Avaliar quais variáveis impactam na fragmentação e eliminação de cálculos em cálice inferior do rim após LECO. Material e Métodos: Avaliamos prospectivamente pacientes submetidos à LECO para tratamento de cálculos de cálice inferior de 5 a 20 mm. O índice de massa corpórea (IMC) e a circunferência abdominal foram medidos em cada caso. Um

Abstract:
This thesis addresses the three principal questions concerning the development of CT urography for investigating haematuria and each question is the subject of a separate chapter. The questions are: What is the reasoning behind using CT urography? What is the optimum diagnostic strategy using CT urography? What are the problems with using CT urography and how may solutions be provided? Haematuria can signify serious disease such as urinary tract stones, renal cell cancer, upper tract urothelial cancer (UTUC) and bladder cancer (BCa). CT urography is defined as contrast enhanced CT examination

Abstract:
This thesis examines various groups of athletes to assess whether they are at risk with regard to kidney stone formation. Particle size distribution analysis (Coulter counter), ultra-structural analyses (SEM) and urine analysis were conducted. The background to various factors relating to stone formation is discussed as well as the general theory behind the techniques employed. The methods utilized and data obtained are described. Particle size distribution analysis and scanning electron· micrographs suggest that marathon runners and cyclists may be at risk with respect to stone formation. Deh

Abstract:
Mice homozygous for the disrupted renal type 11a sodium/phosphate (Na/Pi) cotransporter gene, Npt2, (Npt2 KO) exhibit renal Pi wasting and hypercalciuria, predisposing factors for renal stone formation. We observed that Npt2 KO mice, but not wild-type littermates form renal stones. The renal stones were evident in newborn, weanling and adult mice and composed of calcium (Ca) and Pi. The presence of renal calcification correlated with the absence of Npt2 gene expression and the presence of genes responsible for the synthesis (1alpha-hydroxylase) and catabolism (24-hydroxylase) of 1,25-di

La lithiase urinaire est un problème de santé publique majeur en particulier dans les pays développés occidentaux. Des populations de plus en jeunes sont touchées. En France les dépenses annuelles reliées aux traitements médicamenteux, aux actes chirurgicaux et aux éventuels traitements sous dialyse approchent les 800 millions d’euros. Les calcifications pathologiques de type calculs rénaux sont des composés extrêmement complexes à caractériser et à l’heure actuelle, leur formation in situ au sein du corps humain reste encore entourée de mystères, et ce, malgré de très nombreuses études cliniq
