Despite the modern advancement in endourology, percutaneous nephrostomy play an important role in many urologic conditions, which of the most important is the relief of upper urinary tract in patients with malignancies that interests the ureter or the uretero-vesical junction. The aim of the study is to compare the complications of polyurethane and silicone catheters used for percutaneous nephrostomy in patients with unilateral or bilateral uretero-hydronephrosis secondary to locally advanced abdomino-pelvin malignancies. We have retrospective analyzed 164 patients (p), admitted between January 2013 and December 2016 in Urology Department Sibiu, who benefit from unilateral or bilateral percutaneous nephrostomy for secondary uretero-hydronephrosis with acute renal failure.

Ectopic kidneys though uncommon can be associated with other anomalies of the genitourinary system such as uretero-pelvic junction obstruction, vesicoureteral reflux and upper urinary tract abnormalities. These associations present surgical challenges in an ectopic kidney. We report the surgical management of a right ectopic kidney associated with uretero-pelvic junction obstruction and severe hydronephrosis. A 27-year-old male presented to Zenith Medical and Kidney Center in Abuja with complaints of recurrent, dull right flank pain of 1 year duration. Physical examination revealed a non-tender cystic mass extending from the right iliac fossa to the right hypochondrium. Abdominopelvic computed tomography revealed huge intraperitoneal non-enhancing hypodense ovoid cystic mass difficult to differentiate from the right ureter with severe intraperitoneal mass effect. Retrograde pyelogram done revealed right ectopic pelvic kidney with uretero-pelvic junction obstruction. The patient subsequently had right open Anderson-Hynes pyeloplasty. Intraoperative findings were right ectopic pelvic kidney with uretero-pelvic junction obstruction secondary to intrinsic narrowing at the junction and severe hydronephrosis. Postoperative recovery was uneventful with complete resolution of the presenting symptom. Ectopic kidneys can be associated with uretero-pelvic junction obstruction which presents diagnostic and surgical treatment challenges. Retrograde pyelography is an important radiological armamentarium for the proper diagnosis and subsequent treatment of this condition.

Aim. To evaluate the effectiveness of dismembered flap pyeloplasty for extensive obstruction of the pyeloureteral segment in children. Methods. Dismembered flap pyeloplasty throughout the period 2001-2010 was performed in 9 children (first group), mean age 69 months, 7 (77.8%) boys and 2 (22.2%) girls. Left-sided hydronephrosis was diagnosed in 8 (88.9%) cases, right-sided hydronephrosis - in 1 (11.1%) case. Dismembered flap pyeloplasty was performed in those cases, when after the resection of the ureter and during an attempt to form a direct uretero-pyelo-anastomosis excessive tension of the tissues occurred. In order to replace the resected part of the ureter used was a tubularized U-shaped flap of the renal pelvis, which was anastomosed in an «end to end» fashion with the proximal section of the ureter. The comparison group (second group, 58 patients) included patients who had undergone dismembered pyeloplasty with the formation of uretero-pyelo-anastomosis in the horizontal plane after standard resection of the dysplastic area of the proximal ureter. Results. In the early postoperative period, clinical manifestations of urinary tract infections were recorded in 1 (11.1%) of 9 patients, treated medically. The degree and rate of reduction of the increased anteroposterior size of the renal pelvis after dismembered flap pyeloplasty significantly lagged behind the comparable parameters of patients undergoing standard dismembered pyeloplasty, and at the same time, one year after the operation noted was a marked decrease in the anteroposterior size of the renal pelvis by almost 3 times as compared to the preoperative values. Conclusion. Implementation of dismembered flap pyeloplasty for extensive ureter obstruction makes it possible to achieve good short- and long-term results in the treatment of hydronephrosis in children.

We report a renal transplantation with uretero‐ureterostomy to a normal ureter in a patient with VATER syndrome who had agenesis of the ipsilateral kidney. Anomalous insertion of the native ureter into the cjeculatory duct was subsequently identified when his post‐operative course was complicated by an ureteric leak and hydronephrosis. To our knowledge, this anomaly has not been previously reported. Transplant function is now excellent following temporary percutaneous nephrostomy. Contrast delineation of genito‐urinary anatomy is recommended, before utilizing existing anatomical structures in the urinary tract, in patients. with VATER syndrome.

Full textAbstract:
430 Background: Trimodality bladder sparing therapy has become an accepted treatment for selected patients with muscle-invasive bladder cancer (MIBC). As the presence of hydronephrosis may reduce complete response rate and survival in trimodality therapy, some investigators deem hydronephrosis as a contraindication for bladder sparing. We have developed a tetra-modality bladder sparing therapy (TeMT) consisting of maximal transurethral resection (TUR), induction chemoradiotherapy (CRT), and partial cystectomy (PC) (Koga et al, BJU Int 2012). TeMT which enables surgical consolidation of the original MIBC site, including uretero-vesical anastomosis if necessary, may provide more chance of bladder sparing for patients with hydronephrosis. Methods: In total, 151 patients with cT2-3N0M0 MIBC (median age 69 years, female/male = 33/118, cT2/3 = 100/51) entered tetra-modality bladder-sparing protocol. After maximal TUR and CRT (40 Gy + cisplatin), response was evaluated via cytology, imaging, and tumor-site rebiopsy. Consolidative PC was performed in complete responders, while radical cystectomy was recommended for others. Extension of ipsilateral intrapelvic ureter in pretreatment computed tomography was graded following the Society for Fetal Urology grading system, then patients with grade 2-3 were classified as with hydronephrosis. Response rate to CRT, MIBC recurrence-free survival, and cancer-specific survival (CSS) were compared between patients with or without hydronephrosis. Results: Hydronephrosis was found in 19 patients (14%), and was associated with lower response rate to CRT (42% in hydronephrosis vs 77% in normal, p = 0.03). On an intent-to-treat basis, patients with hydronephrosis (n = 19) had lower 5-yr CSS than those without it (n = 132) (62% vs 85%, p < 0.01). Among the 106 patients who underwent PC as per protocol, patients with (n = 9) and without hydronephrosis (n = 97) had comparable 5-yr MIBC recurrence-free survival (100% vs 97%, p = 0.11) and CSS (100% vs 93%, p = 0.46). Conclusions: Patients with hydronephrosis should not necessarily be excluded from tetra-modality bladder sparing therapy.

Abstract Introduction: Retrocaval ureter (RCU) is a rare congenital anomaly in which the ureter passes posterior to the inferior vena cava, leading to upper urinary tract stasis. This condition is often misdiagnosed and can result in significant complications due to obstructed urine flow. The feasibility of laparoscopic repair is reported in this study. Materials and Methods: We retrospectively analyzed 13 patients who underwent laparoscopic uretero-ureterostomy for RCU between 2020 and 2024. All patients underwent pre-operative evaluation using computed tomography (CT) urogram or magnetic resonance (MR) urogram and nuclear functional imaging. Intraoperatively, a retrograde pyelogram (RGP) was performed to confirm the diagnosis. Laparoscopic uretero-ureterostomy was performed under general anesthesia in all cases. Pre-operative, demographic, and intraoperative data were recorded. Follow-up assessments were conducted to monitor for urinary symptoms and other post-operative complications. Results: All 13 surgeries were completed laparoscopically, with no conversions to open surgery. The average operative time was 118.37 min. Two patients developed Clavien–Dindo Grade 1 complications postoperatively. Five patients experienced stent-related symptoms during their first follow-up, which resolved with symptomatic treatment. At 3 months post-operatively, 69.2% of patients showed asymptomatic static hydronephrosis on serial ultrasound, while 30.8% exhibited resolution of hydronephrosis. A follow-up diethylenetriamine pentaacetate (DTPA) renal scan at 6 months confirmed that there was no obstruction at the anastomotic site in any of the operated patients. Conclusion: Laparoscopic repair of RCU is an effective surgical approach and is increasingly being adopted as part of the urological treatment arsenal.

Full textAbstract:
Introduction: An ectopic ureter is an anomaly in which the ureter has a non-orthotopic distal insertion (not in the bladder trigonum). It has incidence of 1:4000, and it is two to three times more frequent in women. 80% of women with an ectopic ureter have a duplex kidney, and in 80% of the cases the ectopic ureter originates form the upper pole. In 69% of the cases the ectopic ureter has an insertion in the bladder neck or in the urethra, in 31% in the vagina. In men – the insertion is in the posterior urethra - 57%, seminal vesicles - 33%, vas deferens - 10%. The ectopic ureter can be obstructive and therefore cause hydroureteronephrosis of the kidney pole or non-obstructive often refluxing, causing urinary tract infections. A common symptom in women is urinary incontinence Objectivе: Presentation of laparoscopic treatment of an eleven-year-old girl with a left duplex kidney with ectopic ureter and hydroureteronephrosis of the upper pole. A terminolateral ipsilateral uretero-uretero anastomosis was performed. Material and methods: At the age of one upper pole hydronephrosis was found during routine US examination. No further diagnostic evaluation was done, because of the lack of symptoms, the child was followed up only by US by a nephrologist. Currently, ultrasound revealed loss of parenchymal tissue of the upper pole of the left kidney in comparison to previous studies. The anatomy and functionality of the urinary tract were examined using CT Urography, Systoscopy, RPG and VCUG. We started with a cystoscopy - a glide wire and a JJ stent 6CH/24cm were introduced into the ureter draining the lower pole of the duplex kid- ney (the JJ stent had a magnetic end (Magnetic Black-Star), a urethral catheter was inserted. Using three 5 mm ports, a 30-degree camera, the ectopic ureter on the left side was dissected transperitoneally at the level of the iliac vessels. The distal part was cut off to the level of the bladder neck, the normal ureter was located and terminolateral uretero-uretero anastomosis was performed with a running 5-0 monofilament suture (Monocril) ( 13 mm needle). Repositioning of the JJ stent in the ectopic ureter, draining the upper pole, was done under visual control. The urethral catheter was kept postoperatively for 24 hours. Results: No intra- and postoperative complications were observed. No draining tubes were required. The operative time was 270 minutes. The hospital stay was 4 days. Removal of the JJ stent was performed after 6 weeks using a magnetic end catheter. Control ultrasound was performedin the first month after removal of the JJ stent. Discussion: The ectopic ureter is a rare and sometimes difficult to diagnose. The symptoms depend on the insertion of the ureter and the sex of the child. One should consider the possibility of its presence in case of urinary incontinence (dribbling) with normal uroflow, recurrent urinary tract infections, dysplasia or hydronephrosis of the upper renal pole, lumbar pain. Laparoscopic treatment in these cases leads to a shortening of the hospital stay, minimal trauma, excellent aesthetic result and less pain in the postoperative period.

Full textAbstract:
Introduction: Uretero-arterial fistulas are a rare condition. The most frequent clinical sign is hematuria. Since these bleedings occur intermittently, the diagnosis is very difficult. If not discovered, uretero-arterial fistulas involve a very high rate of mortality or even results in loss of kidney function. Case report: The clinical case we describe is an unusual one. After a radical hysterectomy and a subsequent radiotherapy, a hydronephrosis caused by ureteral fibrosis occurred on both sides. Therefore, the patient received bilateral ureteral stents. During a change of the ureteral stents 18 months later, a massive bleeding appeared in the right ureter. Initially, a clear evidence of a fistula was not possible - neither through CT scan nor through selective angiography. There were some indicators of a uretero-arterial fistula, so an endoluminal vessel stent was placed. Subsequently the fistula probably led to an erosion of the vessel stent. Discussion: A fistula between the ureter and the iliac artery (UAF) is a rare complication. The increase in known cases during the last years is linked to the possibility of ureteral stenting since 1978. Until now only 140 cases have been described in literature. The mortality rate through UAF has decreased from 69% in 1980 to 7-23% today. Its development can be traced through the pulsation of the artery and the pressure on the ureter. The most important clinical symptom is bleeding. Diagnosis is generally difficult and represents the real problem. The sensitivity of the standard angiography examination is 23- 41%; it can be improved to 63% using the “provocative” method, which means mobilizing the ureteral stent during examination. The therapy in course of the angiography consists of a simultaneous endovascular stent and/or a co-embolisation. Conclusion: Arterial or uretero-arterial fistulas (UAF) are a rare condition; the diagnosis is very difficult and most of the time the treatment requires a multidisciplinary team.

The most serious urological complication of endometriosis is hydronephrotic renal atrophy secondary to ureteric involvement. As only half of these patients are symptomatic, it is commonly diagnosed late and more by the clinicians awareness and suspicion of this entity. We report a case of an unmarried young female who presented primarily with left loin pain of 2-year duration. She was found to have lower ureteric stricture by an IVU done by her referring doctor. Further workup at our center showed that she had pelvic endometriosis with hydronephrosis secondary to extrinsic ureteric endometriosis. She had a first-degree relative with the same disease. She had no menstrual problems. Diagnostic laparoscopy, biopsy of the lesion, ureteric dilatation with stenting, along with hormonal treatment was given to her as first line of treatment. There was no improvement of the ureteric obstruction even after 6 months of treatment. Finally, surgical excision of the endometrioma, left oophorectomy, along with resection of the ureteric stricture with uretero-ureterostomy was done. This case report includes details of her further management and outcome along with a brief review of literature.

Abstract Regular ultrasound examinations carried out in the second trimester of pregnancy help in detecting many anomalies in the fetal urinary tract. Their percentage ranges from 1% to 3% of all controlled pregnancies. There is a wide spectrum of anomalies that affect the urinary tract, but the most significant are: uretero/hydronephrosis (unilateral or bilateral), kidney agenesis, dysplastic kidney, polycystic and multicystic kidneys, anomalies of ascent, anomalies of kidney rotation or fusion, bladder exstrophy, posterior urethra valve etc. Many of these anomalies do not have impact either on urine flow or on kidney function and hence they can be qualified rather as a condition than as a disease. At the same time, most of the hydronephroses that are seen prenatally are being resolved spontaneously, and they are not detected neither presented postnatally as uretero/hydronephroses of unobstructed type and do not require surgical treatment. Only one tenth of these anomalies are subject to active surgical treatment. Therefore, the assessment of these conditions should be done by a specialized team, who will make adequate therapeutic decisions based on clinical guidelines, as well as will advise the parents on the future clinical implications of the detected anomaly.

BACKGROUND: Congenital stenosis of the ureterоpelvic junction is the most common cause of hydronephrosis in children.
 AIM: This systematic review aimed to search and analyze modern literature from 1998 to 2021 on the treatment and postoperative follow-up of children with severe hydronephrosis in the first year of life and study the long-term results.
 MATERIALS AND METHODS: Literary sources were searched in PubMed, Web of Science, Scopus, Google Scholar, and eLibrary databases. The following keywords were used to search for English sources: congenital hydronephrosis, severe hydronephrosis, operative treatment, uretero-pelvic junction obstruction infant, children, neonatal, and infancy. Five full-text articles that meet the criteria were included for analysis.
 RESULTS: A total of 355 patients were included in the publications. Antenatal screening was described only in two studies. The average age of children at the time of surgery was five months (one to six months). All the authors noted that due to pyeloplasty in the first year of life, the renal parenchyma exhibited a significant increase in thickness; the indicators in dynamics increased by an average of 1.5 times during the year. The size of the renal pelvis decreased by 50%67%. The data of radioisotope scintigraphy were variable; however, in the long-term period, improvement in renal function was noted in all publications.
 CONCLUSIONS: This systematic review shows the long-term results of early pyeloplasty in congenital hydronephrosis in young children. A significant decrease in the pelvis and an increase in the thickness of the parenchyma were observed, both of which are an advantage for the restoration of renal function. However, no single algorithm can predict the recovery of renal parenchyma. An accurate assessment of renal parenchymal function should be confirmed by a prospective, randomized, long-term, follow-up study with a large number of cases.

Background: Megaureter is a non-specific term implying a spectrum of anomalies associated with pathologically excessive ureteral diameter. It implies no particular unifying pathophysiologic principles but merely groups together a spectrum of anomalies associated with increased ureteral diameter. To analyse the clinical profile and various investigation modalities used in diagnosing primary obstructive megaureter.Methods: This prospective study was conducted in March 2017 to August 2019 at the Institute of Child Health and Hospital for Children (ICH and HC), Egmore, Chennai.Results: The most common presentation was febrile urinary tract infection, second most presentation was asymptomatic patients, on post-natal evaluation of antenatally diagnosed cases. The most common finding on the antenatal scan is uretero-hydronephrosis. Maximum incidence of ureteric size - between 1 and 1.5 cms. 13 patients underwent surgery after an initial period of observation from the time of presentation. These patients belong to the period of infancy. The coincidence of circular muscle hyperplasia and longitudinal muscle hypoplasia was noted in 18 patients.Conclusions: In this study, patients presented during infancy were initially observed, prior to surgical intervention. But those patients presented beyond infancy were evaluated and intervened surgically during the same admission. Cohen’s uretero-neocystostomy through intra-vesical approach is the surgical procedure of choice, in the majority of the cases, in this study.

Introduction: Large vesical calculi are rare conditions in urology due to the advancement of image exams in the last decade. Urinary bladder stones represent 5% of all urinary tract calculi and large calculi are defined as weighing more than 100 grams. Case Report: We report the case of a 56-year-old man with large vesical calculus measuring 17 × 13 × 16 cm (weight of 2730 g) in association with renal exclusion due to staghorn calculus in the right kidney and bilateral uretero-hydronephrosis due to bladder obstruction. Conclusion: Computed tomography stands as the exam of choice to diagnose and delimit any urinary calculi. Open surgery is preferred for large vesical stones and bladder outlet obstruction must be investigated, especially in men to exclude prostate increase.

Emphysematous cystitis, a rare entity within the spectrum of urinary tract infections, poses a crucial diagnostic challenge, particularly when it occurs in diabetic patients [1]. Here, we present the case of a 74-year-old man with type 2 diabetes and chronic tobacco use, who was admitted to the emergency room for right lower back pain associated with dysuria in a febrile context. This condition, characterized by the presence of gas in the bladder and/or its wall, is often associated with aero-anaerobic microbial fermentation, placing diabetic patients in a high-risk category. The physiopathological complexity of emphysematous cystitis underscores the importance of understanding the underlying mechanisms of this condition, particularly in individuals with risk factors such as diabetes and smoking. In the current clinical context, where the prevalence of diabetes is constantly rising, the rapid recognition of these atypical manifestations becomes imperative for appropriate management. This specific case, though uncommon, highlights the necessity of increased vigilance among diabetic patients presenting with urinary symptoms, thus emphasizing the importance of a proactive clinical approach. A thorough examination of this case provides an opportunity to explore the links between diabetes, smoking, and emphysematous cystitis, enriching our understanding of the risk factors and physiopathological mechanisms associated with this rare clinical entity.

Summary Spontaneous ureteric rupture is a rare phenomenon which can be traumatic or non-traumatic that may arise from ureteric obstruction, trauma, mucosal inflammation from urolithiasis, connective tissue disease or retroperitoneal fibrosis. High pressure chronic retention is characterised by noctural enuresis, a tense palpable bladder, hypertension, progressive renal impairment, bilateral hydronephrosis and hydroureter on imaging. Obstructive urological symptoms are typically absent in uncomplicated cases. We report the case of a 69-year-old male who presented with high pressure chronic retention and spontaneous ureteric rupture demonstrated on a noncontrast CT. This patient was managed with a urethral catheter on free drainage and a retrograde ureteric stent. The patient’s condition improved, and the stent was removed after a uretero-pyeloscopy which revealed no extravasation. He later underwent a successful transurethral resection of the prostate.

Female hypospadias is a rare congenital malformation, often underdiagnosed compared to its male counterpart. We present the case of a 4-year-old girl with a history of poorly managed heart disease, diagnosed at the age of 2 after several episodes of recurrent urinary tract infections. Abdominopelvic ultrasound revealed bilateral pyonephrosis and bilateral uretero-hydronephrosis (UHN). Clinical examination and additional investigations led to the diagnosis of female hypospadias with a common channel measuring between 1 to 15 cm in length. Treatment involved the apicalization of the urethral meatus and a meatoplasty using Hendren’s technique, followed by uncomplicated postoperative recovery. This study highlights the importance of distinguishing female hypospadias from urogenital sinus in females to optimize diagnosis and treatment. The results show that surgical correction is effective, offering good postoperative outcomes.

Full textAbstract:
Pelvi-ureteric junction obstruction is one of the most common urological conditions found in children. Horseshoe kidneys are a predisposing factor and to find a vascular anomaly causing the obstruction is rare. A 2-year-old girl with two episodes of culture-positive febrile urinary tract infections (UTI), was found to have right sided hydronephrosis. Renal scan revealed decreased functioning of right kidney with scars. A contrast CT scan showed a horseshoe kidney with pelvi-ureteric junction obstruction on right side with dilatation of renal pelvis. During laparoscopic pyeloplasty, lower pole crossing vessels were detected, not reported on CT scan. A dismembered pyeloplasty with transposition of uretero-pelvic anastomosis anterior to lower pole vessels was done. Anomalous vasculature of kidney should be kept in mind during surgery in such cases. A dismembered pyeloplasty along with transposition of anastomosis is necessary to prevent recurrence.

Full textAbstract:
The hydronephrotic kidney, resulting from an uretero-pelvic junction obstruction (UPJO), presents commonly as a clinical condition, with the presence of usually no more than 1‑2 liters in the collecting system, but a very small number of cases of giant hydronephrosis (GHs) has been reported in adults. In this case report a 53-year-old male was admitted to the Vamshodaya Hospital Kolar, Karnataka, India in November 2023 with an abdominal pain since 15 days and abdominal distention since 6-months. Computed tomography was performed, finding large thin walled cystic mass in right side of abdominopelvic region (40x32x27cm) showing few incomplete septations, fluid density within lesion and causing significant mass effect and displacing the rest of the abdominal contents. Such cases are rarely presented; therefore the aim of the present case study was to document a clear case of GH resulting from UPJO.

Purpose: In some patients with a ureteral stone without uretero-hydronephrosis, it is difficult to determine the location of the stone. The objective of the present study was to investigate the changes in renal papillae using unenhanced computerized tomography (uCT) and determine the side of calculi using the renal papillary findings in patients with a ureteral stone. Methods: uCT data from 81 patients were retrospectively reviewed for this study. The inclusion criteria were unilateral ureteral calculi, no renal calculi and no hydronephrosis. For each patient, three measurements of CT attenuation of 0.05 cm2 area were made in the tip of the interested renal papillae, both stone side and non-stone side. Student’s t test was used for statistical analysis. Results: Forty-one right-sided and 40 left- sided isolated unilateral ureteral calculi patients were evaluated by uCT exam. The average attenuations of the tip of the papillae in stone side and non-stone side were 34.1 Hounsfield units (HU) and 30.6 HU, respectively. There was a statistically significant difference between stone and non-stone sides (p< 0.05). Conclusion: During routine practical uCT applications, it can be difficult to distinguish phleboliths, ureteral stone or the existence of non-opaque ureteral stone, so papillae density measurements can be a practical method to identify the existence of ureter stone and its location (side).

Objective: To evaluate the clinical complications and functional outcomes associated with the modified Y-pouch neobladder technique, in particularly those related to the prevention of anastomosis stricture. Materials and Methods: Functional outcomes and associated complications were evaluated in 25 patients (23 men, 2 women) who underwent radical cystectomy with Y-pouch neobladder by isolating 50 cm of the ileum between October 2010 and December 2020. Clinical complications included anastomosis stricture formation, hydronephrosis, pyelonephritis, vesical stone formation, and renal deterioration. Results: No cases exhibited uretero-neobladder anastomosis stricture, urethro-neobladder anastomosis stricture, or vesical stones. In addition, no complications were observed in relation to metabolic acidosis. One year after surgery, daytime and nighttime continence rates among patients were 88% and 72%, respectively, with almost every case exhibiting near-normal voiding frequency. The average maximal neobladder capacity was 425.60±20.83 ml with a mean follow-up period of 2.8 years. There was a no statistically significant increase in creatinine with values of 1.45 mg/dl, 1.14 mg/dl, 1.21 mg/dl, and 1.35 ml/dl being recorded at preoperative baseline, 3, 6 and 12 months, respectively. Conclusions: The Y-pouch neobladder created by isolating 50 cm of the ileum showed a low incidence of uretero-neobladder anastomosis and urethra-anastomosis stricture rate. In addition it was a straightforward procedure with a quickly reconstructed reservoir, had good functional outcomes which were comparable to most popular orthotopic neobladders, had no significant increase in postoperative creatinine levels and improved quality of life for patients.

Full textAbstract:
Retrocaval location of the ureter in combination with aberrant renal vessels is a rare and complex urinary system malformation that requires careful verification. Currently, the most appropriate method for diagnosing retrocaval ureter is contrast-enhanced computed tomography. With the development of hydronephrosis or ureterohydronephrosis, the patient underwent laparoscopic ureteroplasty. Surgical treatment of retrocaval ureter involves resection of the altered ureter or pelvic–ureter segment with the formation of uretero-ureteral anastomosis or ureteropieloanastomosis anterior to the inferior vena cava. This article presents a successful laparoscopic ureteroplasty in a child with complex urodynamics of the urinary tract. Considering the presence of two levels of ureteral vascular crossing in the clinical example, pyelo-ureteral segment was performed to relocate the ureter in front of the inferior vena cava and aberrant inferior polar vessels. The patient was discharged in satisfactory condition to the outpatient stage of treatment, with subsequent hospitalization in the urological department. Retrocaval location of the ureter in combination with aberrant renal vessels is a rare congenital anomaly that requires prompt examination in a specialized clinic and an individual examination and treatment plan.

The tuberous sclerosis complex (TSC) is highly variable as far as its clinical presentation is concerned. For the implementation of appropriate medical surveillance and treatment, an accurate diagnosis is compulsory. TSC may affect the heart, skin, kidneys, central nervous system (epileptic seizures and nodular intracranial tumors—tubers), bones, eyes, lungs, blood vessels and the gastrointestinal tract. The aim of this paper is to report renal manifestations as first clinical signs suggestive of TSC diagnosis. A 20-year-old patient was initially investigated for hematuria, dysuria and colicky pain in the left lumbar region. The ultrasound examination of the kidney showed bilateral hyperechogenic kidney structures and pyelocalyceal dilatation, both suggestive of bilateral obstructive lithiasis, complicated by uretero-hydronephrosis. The computer tomography (CT) scan of the kidney showed irregular kidney margins layout, undifferentiated images between cortical and medullar structures, with non-homogenous round components, suggestive of kidney angiomyolipomas, bilateral renal cortical retention cysts, images of a calculous component in the right middle calyceal branches and a smaller one on the left side. The clinical manifestations and imaging findings (skull and abdominal and pelvis CT scans) sustained the diagnosis.

Introduction Forgotten indwelling ureteral stents can cause significant urological complications. Only few cases are reported after kindney transplantation. Materials and Methods We present a case of a 39-year-old woman, transplanted in 1993 and referred to our Transplant Center 8 years later, because of a serious urinary tract infection with renal function impairment. Abdominal CT scan showed pyelonephritis and hydronephrosis in the transplanted kidney and the presence of a calcific ureteral stent, which had been forgotten in situ for 8 years. The stent was removed, but it was impossibile to replace it with a new stent both retrogradely and anterogradely, because of a tight obstruction of the mid ureter. So a uretero-ureteral anastomosis with up urinary tract was performed. Results No intra- or post-operative complications occurred. At 9 years’ follow-up, the patient shows an optimal renal function, with no urinary tract infection. Discussion A forgotten ureteral stent in a trasplanted kidney can cause a lot of complications and can lead to graft loss. The prosthesis may cause an irreversibile ureteral damage, so, as in our experience, forgetting a ureteral stent can result in a complex surgery.

Full textAbstract:
Background: Uretero-Pelvic Junction Obstruction (UPJO) is an important cause of hydronephrosis in pediatric age group. The choice of treatment could be conservative or surgical. Commonly Anderson-Hynes pyeloplasty is practiced with internal, external or partly internal partly external stent.Methods: This was a prospective study of 40 patients with UPJO, divided into 2 groups consecutively, each consisting of 20 patients. All patients underwent open Anderson-Hynes pyeloplasty. Cummings stent were given in one group for drainage and conventional DJ stent were used for another group.Results: The mean hospital stay was lesser in DJ stent group (8.4±2.13) compared to Cummings stent group (11.4±0.68), not only in respect to primary admission, but also including readmission for cystoscopic stent removal. The incidence of complications was also fewer in Cumming stent group. Stent migration and urinary tract infection (UTI) were more associated with DJ stent (2 each) than Cumming stent (0 each). However, dysuria was more in case of cumming stent (2 patients) than DJ stent (1 patient).Conclusions: The mean hospital stay in DJ stent insertion is less even if duration for cystoscopic removal is considered. The complication of stent removal and UTI are more with DJ stent though dysuria is more in case of Cummings stent.

Full textAbstract:
Background: Laparoscopic (LP) and robot-assisted pyeloplasty (RAP) are minimally invasive techniques for correcting uretero-pelvic junction obstruction (UPJO). We retrospectively compared the clinical outcomes of all adults who underwent RAP (n = 41) to those who underwent LP (n = 24) for UPJO at our institution between 2003–2022. Methods: Age, sex, body mass index, surgical side, past abdominal/endoscopic surgeries, pre- and postoperative renal scans, pre- and postoperative serum creatinine levels, operative time (OT), presence of crossing vessels, estimated blood loss, postoperative complications, length of hospital stay, time to JJ stent removal, follow-up length, and postoperative hydronephrosis were analyzed. Results: The groups were demographically comparable. The mean total and skin-to-skin OTs (minutes) were significantly longer in the RAP group than in the LP group (242.4 ± 55 vs. 161.4 ± 40 p < 0.001; 163.7 ± 41.8 vs. 124.3 ± 30.3 p = 0.006, respectively). Hospital stay (days) was shorter in the RAP group (3.3 ± 2.1 vs. 7.3 ± 2.5 p < 0.001). Postoperative complication rates were identical for both groups. The LP group had a significantly longer follow-up period (85.2 ± 73 vs. 19 ± 14 months p < 0.001). The success rates for the LP and RAP groups were 87.5% and 90.6% (p = 0.708). Conclusions: RAP achieves equivalent results to LP, in adult patients. A longer OT may be expected with the robotic system since it can handle more complicated cases.

Background:Chronic intestinal pseudo-obstruction can be a rare complication of systemic lupus erythematosus. It is often late to be identified in contrast to other commoner organs involvement in systemic lupus erythematosus such as nervous system, joint and kidney.Objectives:To report a case of uncommon gastrointestinal complication of lupus, with associated hydronephrosis at the ureter, with treatment delay.Methods:We report a case of chronic intestinal pseudo-obstruction.Results:A 34 year old, with ten-year history of lupus nephritis, presented with recurrent abdominal pain and diarrhoea past nine months. The patient had just been diagnosed as end-stage renal failure a year ago, on regular haemodialysis. For the past ten years, the patient was not able to tolerate immunosuppressant due to the multiple episodes of infections, including shin carbuncle, herpes zoster, breast abscess and catheter-related candida/bacterial infections. However, the patient did not have any other major organs manifestations of lupus for the past ten years. The patient was apyretic. Multiple stool cultures were negative including Clostridium difficile. The abdominal radiography showed dilated small bowel with diffuse thickening of large and small bowels on computed tomography. Bilateral uretero-hydronephrosis was also noted without any evidence of obstructive uropathy on imaging. Ileocolic resection was done for presumed intestinal obstruction and the ileocolic biopsy did not reveal any granuloma, malignancy or vasculitis except for non-specific inflammation of cecum. Cytomegalovirus inclusion body was absent as well. Tuberculosis culture was negative. Oesophagoduodenoscopy and colonoscopy were offered in view of persistent unexplained loose stool and abdominal pain. But unremarkable findings were noted from multiple biopsy specimens of the small and large bowels. Second relook of the initial hemicolectomy specimen with special actin immunostain on the smooth muscle revealed degenerative changes of the muscularis propria. These were evidenced by cytoplasmic vacuolation, atrophy and pyknotic nucleus of the smooth muscle cells with surrounding oedema. Smooth muscle dysmotility could be the underlying pathology of this patient presentation. The patient responded well to intravenous immunoglobulin followed by azathioprine in addition to prednisolone and prokinetic agent.Conclusion:Prompt recognition is pivotal in this case could have prevented the unnecessary surgical intervention earlier. It is potentially reversible. Long term prognosis of this rare entity is, however, varying.Disclosure of Interests:None declared

Full textAbstract:
Urothelial cancer is a family of neoplasms characterized by an extremely high incidence of kidney impairment throughout its whole natural history; furthermore, surgical and medical treatments may often worsen kidney function or cause renal adverse events. The role of the nephrologist would be key to support urologists and oncologists toward a really multidisciplinary management of these patients. First, nephrologists could help to deal with episodes of acute kidney injury, or of a worsening of chronic kidney disease due to obstruction/infections, episodes which are quite common in patients with non-muscle-invasive tumors undergoing several trans-uretral resections. In muscle-invasive neoplasms, the nephrologist could contribute to reduce the number of patients unsuitable for cisplatin-based neo-adjuvant (or adjuvant) chemotherapy or of those who cannot complete the scheduled treatment due to a deterioration in their kidney function. In patients receiving nephrectomy (in the case of upper urinary tract neoplasms) or cystectomy (in the case of bladder cancers), renal function deterioration is also extremely frequent; post-operative hydronephrosis, pyelonephritis, and uretero-enteric strictures indeed represent other potentially modifiable factors associated with a decrease in kidney function. Finally, in the metastatic setting, the nephrological management of renal toxicities from systemic therapies, including novel immune-checkpoint inhibitors, would also be increasingly important. Here, we highlight the need for the involvement of the nephrologist in the complex management of these patients, thus advocating for a really comprehensive multidisciplinarity.

Introduction: Minimal invasive intervention is preferred to open surgery in the treatment of kidney stone. Our goal is to assess the efficacy of ultrasound-guided mini-percutaneous nephrolithotripsy in lateral position for patients with renal stone disease. Methods: Prospective study on patients who underwent mini-percutaneous nephrolithotripsy in our department of Viet Duc hospital from 01/2021 to 12/2022. Spinal anesthesia was applied, patients were placed in the lateral position, using guidance of ultrasound, uretero-nephroscope, and nephrolithotripsy. The main outcomes were the rate of stone clearance and intraoperative or postoperative complications. Results: One thousand four hundred sixty-five patients, 1056 males (72.08%), mean age of 45.13±24.31 year-old. Pelvic stones accounted for 11.87%, lower caliceal stones 9.76%, and staghorn stones 19.41%. The stones occurred mostly in the left kidney (61.22%). Preoperative hydronephrosis cases detected by multi-slice computer tomography showed 24.09% at level 2 and 11.74% at level 3. Renal stone size: mean length: 3.1±0.76 cm, width: 1.82±0.56 cm. Mean operative time was 67.23±27.18 min (35–120 min). Intraoperative complications included 35 cases (2.38%) of hemorrhage not requiring blood transfusion. Postoperative complications rate was 2.66%. The mean length of hospital stay was 4.57±2.64 (2–8) days. Nephrostomy tube was removed after 2.87±1.43 days. Early stone-free rate was 82.98%. At 1-month follow-up, JJ stent removal was performed, and the stone-free rate achieved 96.87%. Conclusion: This method showed some benefits compared to traditional nephrolithotripsy. It is a useful, safe method and therefore highly recommended in the treatment of kidney stones.

Full textAbstract:
Background Intravesical recurrence (IVR) after surgery for upper tract urothelial carcinoma (UTUC) is a clinical problem. We investigated if preoperative invasive diagnostic modalities (IDM) such as antegrade/retrograde uretero-pyelography and/or selective urine cytology/barbotage, and URS with or without concomitant biopsy are associated with IVR after radical surgery for UTUC. Risk of death from urothelial cancer and all causes was investigated as secondary outcomes. Methods We investigated a population-based cohort of 1038 consecutive patients subjected to radical surgery for UTUC 2015–2019 in Sweden, using the Bladder Cancer Data Base Sweden (BladderBaSe 2.0), comprising all patients in the Swedish National Registry of Urinary Bladder Cancer. Risk estimates of IVR, death from urothelial cancer, and all causes was assessed using multivariable Cox regression models. Results The study included 536 cases with and 502 without preoperative IDM. IDM was associated with increased risk of IVR (HR 1.24, 95% CI 1.03–1.52) and risk of urothelial cancer death (HR 1.56, CI 1.12–2.18), compared to no IDM after a median follow-up of 1.3 yrs. Stratified analysis for tumor location showed that IDM was associated with risk of IVR in ureteric cancer (HR 1.66, 95% CI 1.21–2.28) but not in renal pelvic cancer (HR 1.07, 95% CI 0.81–1.41). Limitations included the observational setting and the lack of variables such as tumour grade, multifocality and preoperative hydronephrosis. Conclusions Worse outcomes for patients subjected to preoperative IDM highlight the need for carefully considering diagnostic decisions for UTUC patients, specifically in tumours located in the ureter.

Full textAbstract:
Pelviureteric junction obstruction (PUJO) is a functional or anatomic obstruction of urine flow from the renal pelvis into the ureter. The causes of PUJO are congenital, acquired, intrinsic and extrinsic. Pelviureteric junction obstruction ultimately will lead to hydronephrosis which can progress to permanent renal impairment. The standard procedure to relieve obstruction is open, laparoscopic or robotic pyeloplasty.In our study 30 patients with primary PUJO were randomised into two groups of 15 each using a computer-generated randomised table. Anderson Hynes Open pyeloplasty was performed on 15 patients, and laparoscopic pyeloplasty was performed on 15 patients. Both procedures were compared for efficacy in terms of subjective outcomes (post-operative pain, activity level) and objective outcomes (operative time, complications, recovery time/hospital stay, improvement in renal function, cosmesis, success rate). Standard inclusion and exclusion criteria were followed.Laparoscopic pyeloplasty has a comparable success rate to open pyeloplasty and is an effective minimally invasive treatment option for PUJ obstruction. Laparoscopic pyeloplasty is emerging as the new standard of care for PUJ obstruction.

ObjectiveTo analyze from a pathological perspective the differences between intermittent and persistent hydronephrosis in children with uretero-pelvic junction obstruction.Methods23 children who underwent unilateral dismembered pyeloplasty (Anderson-Hynes operation) for intermittent hydronephrosis from September 2017 to March 2024 were included in the observation group. They were compared with a control group consisting of 23 children with persistent hydronephrosis matched for age, gender, and affected side. All children had the narrowed segment surgically excised during the operation, while other obstructive causes (such as polyps, crossing vessels, or tumor compression) were excluded. The specimens were analyzed for muscle and collagen content using Masson's trichrome staining, and the collagen-to-muscle ratio (CMR) was calculated. The number of Cajal-like cells was quantified with c-kit immunohistochemical staining. For all slides, 10 random fields of view were selected under a 400× optical microscope to record pathological data and calculate mean values. Pathological indicators between the two groups were compared using the T-test and the Chi-square test, with P &lt; 0.05 considered statistically significant.ResultsThe observation group showed a significant difference in the number of fields with low, medium, and high densities of Cajal-like cells compared to the control group [132 (57.4%) vs. 173 (75.2%); 70 (30.4%) vs. 38 (16.5%); 28(12.2%) vs. 19 (8.3%), P &lt; 0.001]. The uretero-pelvic junction in children with intermittent hydronephrosis had lower collagen content, higher muscle content, and a more regular arrangement. The collagen-muscle ratio was significantly lower than that in children with persistent hydronephrosis [(1.59 ± 0.65) vs. (3.98 ± 1.19), P &lt; 0.001].ConclusionCompared with persistent hydronephrosis, the narrowed segment at the uretero-pelvic junction in children with intermittent hydronephrosis has a higher density of Cajal-like cells; lower collagen content, and higher muscle content (lower collagen-muscle ratio).

Abstract Purpose Few tools are available to predict uretero-lithotripsy outcomes in patients with ureteral stones. Aim of our study was to develop a nomogram predicting the probability of stone free rate in patients undergoing semi-rigid uretero-lithotripsy (ULT) for ureteral stones. Methods From January 2014 onwards, patients undergoing semi-rigid Ho: YAG laser uretero-lithotripsy for ureteral stones were prospectively enrolled in two centers. Patients were preoperatively evaluated with accurate clinical history, urinalysis and renal function. Non-contrast CT was used to define number, location and length of the stones and eventually the presence of hydronephrosis. A nomogram was generated based on the logistic regression model used to predict ULT success. Results Overall, 356 patients with mean age of 54 years (IQR 44/65) were enrolled. 285/356 (80%) patients were stone free at 1 month. On multivariate analysis single stone (OR 1.93, 95% CI 1.05–3.53, p = 0.034), stone size (OR 0.92, 95% CI 0.87–0.97, p = 0.005), distal position (OR 2.12, 95% CI 1.29–3.48, p = 0.003) and the absence of hydronephrosis (OR 2.02, 95% CI 1.08–3.78, p = 0.029) were predictors of success and these were used to develop a nomogram. The nomogram based on the model presented good discrimination (area under the curve [AUC]: 0.75), good calibration (Hosmer–Lemeshow test, p > 0.5) and a net benefit in the range of probabilities between 15 and 65%. Internal validation resulted in an AUC of 0.74. Conclusions The implementation of our nomogram could better council patients before treatment and could be used to identify patients at risk of failure. External validation is warranted before its clinical implementation.

Full textAbstract:
Horseshoe kidney (HSK) is a congenital defect of the urinary tract that occurs in 0.25% of the general population. Laparoscopic Vascular Hitch (LVH) according to Hellstrom-Chapman represent an alternative approach in treatment of extrinsic hydronephrosis by crossing vessels (CV) in pediatric age. In our Department from 2006 to 2016, 36 children with extrinsic-Uretero-Pelvic-Junction (UPJ)-Obstruction (UPJO) underwent laparoscopic vessels transposition. Over the last 4years, we have treated three patients with extrinsic hydronephrosis in HSK; two males and one female respectively of 6, 7 and 8years. The side affected was the left in all patients; symptoms of onset: recurrent abdominal pain, vomiting with associated intermittent hydronephrosis at ultrasonography. The preoperative examinations performed were: ultrasound/Doppler scan, MAG3-renogram, functional-magnetic-resonance-urography (fMRU). Mean operative time was 120’; median hospital stay 3- days. Intraoperative diuretic-test (DT) confirmed an extrinsic-UPJO in all patients. No JJ-stents and drain were used and there were no perioperative complications. Clinical and ultrasound follow-up (18 months-4 years) show resolution of symptoms and decrease in hydronephrosis grade in all patients. Our series is the largest in pediatric population by a revision of the literature. We believe that LVH is feasible in patients with symptomatic hydronephrosis by CV in HSK. Intraoperative-DT and the correct selection of patients are crucial to the success of the technique. According to us, this procedure is appropriate in those cases where the UPJ-anatomy is disadvantageous to a resection/re-anastomosis between ureter and renal pelvis. Our initial results are encouraging, although long-term follow- up and a more significant patient sample are required.

Full textAbstract:
Introduction This study aimed to evaluate the initial outcomes of a novel transfixing uretero-enteral anastomosis technique in robot-assisted radical cystectomy (RARC) with ileal conduit in an intracorporeal urinary diversion (ICUD), focusing on its potential to reducing the incidence of uretero-enteric anastomotic stricture (UEAS). Methods The study subject is 11 patients who underwent RARC and ileal conduit created as an ICUD at a single cancer center between 2022 and 2024. The technique involved opening the ventral side of the oral end of the separated ileum approximately 5 cm apart. Two small holes were made 2 cm from the oral end on the dorsal side, through which the ureter passed to the luminal side. The distal end of the ureter was spatulated, and four knotted sutures were placed at the base using 4-0 absorbable sutures. The distal end of the ureter was anchored using two knotted sutures, and the liberated portion was closed using 3-0 absorbable suture in a running fashion. Results The median total operation time was 418 min (range: 269–467 min), with a median console time of 93 min (range: 80–129 min) for urinary diversion. Two patients required temporary stent reinsertion because of hydronephrosis; however, no pyelonephritis occurred. Two patients (18.2%) had complications of Clavien-Dindo classification 3 or higher, both of which only required temporary stent reinsertion. Postoperative renal function was preserved in all the patients. Conclusions In our initial experience, the transfixing uretero-enteral anastomosis technique was successful in stabilizing anastomoses in ICUD.

Uretero-Iliac Artery Fistula: a rare cause of haematuria A 90-year-old male presented to our hospital with a onemonth history of intermittent gross hematuria. He had stage II rectal cancer and received neo-adjuvant concurrent chemoradiotherapy and low anterior resection 5 years ago. Additionally, he was under regular bilateral ureteral catheter replacement due to radiation related ureteral stricture for two years.\r\nDuring examination, there was no abdominal tenderness or flank pain. Urine analysis showed pyuria and hematuria. Abdominal and pelvic computed tomography without contrast medium revealed only bilateralwithout contrast medium revealed only bilateral hydronephrosis. After admission, several hematuria episodes that required blood transfusions and bladder irrigation occurred at an interval of 3 days and resolved spontaneously. Cystoscopy was unmarkable except bleeding from right ureteral orifice during ureteral stent replacement. Concerns for a ureteral arterial fistula prompted an angiogram, which later on proved the existence of a fistula with pseudoaneurysm(Figure 1) between external iliac and distal right ureter(Figure 1). A stent graft was placed from the common iliac into the right external iliac artery. After stent-graft deployment, the aneurysm is no longer opacified. At the 2-month follow-up, no hematuria recurrence was detected.\r\n

Full textAbstract:
AbstractBackgroundBenign uretero‐ileal anastomotic stricture (UIAS) is a potentially serious complication that can arise after radical cystectomy (RC) and subsequent urinary diversion. To preserve residual renal function and improve prognosis, it is crucial to derive insights from experience and tailor individualized treatment strategies for different patients.Patients and MethodsFrom October 2014 to June 2021, a total of 47 patients with benign UIAS underwent endoscopic management (n = 19) or reimplantation surgery (n = 28). The basic data, perioperative conditions, and postoperative outcomes of the two groups were compared and analyzed to evaluate efficacy.ResultsComparing preoperative and postoperative clinical efficacy within the same group, the endoscopic group showed no significant differences in creatinine and blood urea nitrogen (BUN) levels before surgery or after extubation (p > 0.05). However, significant differences were observed in glomerular filtration rate (GFR) levels on the affected side before surgery and after extubation (p < 0.05). In contrast, the laparoscopic reimplantation group did not exhibit significant differences in creatinine, BUN, or GFR levels of affected side before surgery and after extubation (p > 0.05). Postoperative clinical efficacy showed no significant difference in creatinine and BUN levels between the two groups (p > 0.05). However, GFR values of affected side in the endoscopic treatment group decreased more than those in the laparoscopic reimplantation group (p < 0.05). Additionally, the laparoscopic reimplantation group was able to remove the single‐J tube earlier than the endoscopic treatment group (p < 0.05), had a lower recurrence rate of hydronephrosis after extubation (p < 0.05), and experienced a later onset of hydronephrosis compared to the endoscopic treatment group (p < 0.05).ConclusionsBased on our experience in treating UIAS following RC combined with urinary diversion, laparoscopic reimplantation effectively addresses the issue of UIAS, allowing for the removal of the ureteral stent relatively soon after surgery. This approach maintains long‐term ureteral patency, preserves residual renal function, reduces the risk of ureteral restenosis and hydronephrosis, and has demonstrated superior therapeutic outcomes in this study.

Full textAbstract:
Introduction: Suprapubic catheter (SPC) and bladder indwelling catheter (BIC) placement are among the most common urological procedures. Inadvertent misplacement of the catheter tip into the ureteral orifice is an infrequent event with potentially critical complications. Case Presentation: We describe two cases of inadvertent intraureteral misplacement of an SPC and a BIC. A 66-year-old man with chronic kidney disease (CKD) stage G3b, urethral stenosis, long-term SPC who attended the emergency room (ER) 6 hours after the last catheter replacement due to low back pain, fever, deterioration of the general condition, anuria, acute kidney injury (AKI); CT-scan revealed a left uretero-hydronephrosis secondary to obstruction of the catheter balloon misplaced inside the distal ureter. A 59-year-old woman with CKD stage G3b, post-radiotherapy cystitis, and small capacity bladder, long-term BIC who attended the ER a few hours after the last BIC replacement due to abdominal pain, anuria, AKI; CT-scan revealed left hydronephrosis secondary to catheter obstruction within the distal ureter. In both patients, management was conservative, consisting of removing the catheter and repositioning it inside the bladder, in addition to hydration and antibiotherapy. Conclusions: These cases illustrate that awareness of this rare complication can be prevented by confirming the correct positioning of SPC or BIC after its replacement. Early detection and management of this complication can prevent a serious clinical setting.

Full textAbstract:
Objective: To assess the diagnostic efficacy of integrating B-mode and color Doppler capabilities of ultrasound (US) to establish a robust standalone diagnostic tool for the diagnosis of ureteric stones as an alternative to non-contrast-enhanced computed tomography (NCCT).Methods: A total of 140 consecutive patients diagnosed with ureteric stones using NCCT were enrolled. On the same day, US in both B-mode and Color Doppler was performed by an experienced radiologist who was blinded to the NCCT scan results. The diagnostic rate of US for stone detection was recorded. Additionally, baseline patient and stone characteristics were analyzed for their association with the accuracy of stone detection using US.Results: US exhibited a high sensitivity of 91.43%, detecting 128 out of 140 stone foci. Notably, ureteric stones in the proximal and uretero-vesical junction (UVJ) segments were readily identifiable compared to those in the pelvic region (p = 0.0003). Additionally, hydronephrosis enhanced the US's ability to detect stones (p < 0.0001). Conversely, abdominal gases and obesity adversely affected US capabilities (p < 0.0001 and p = 0.009, respectively). Stone side, size, and density showed no statistically significant impact (p > 0.05).Conclusions: US with its color Doppler capabilities could serve as a reliable and safe alternative imaging modality in the diagnostic work up of patients with ureterolithiasis. Factors including stone location, Hydronephrosis, weight and abdominal gases significantly influenced its accuracy.
