Abstract
PURPOSE To evaluate the role of certain radiological parameters and patient characteristics in predicting the success of endoscopic treatment in ureteral stricture disease. METHODS Fifty one adult patients with ureteral stricture disease (< 1 cm) after developing due to upper ureteral stones with ureteroscopic laser disintegration were included and in addition to stone and patient parameters, radiological parameters including ureteral wall thickness (UWT) at the impacted stone site were also measured on computed tomography (CT) images. Patients were divided into two groups: Group 1: Patients with endoscopic treatment success and Group 2: Patients with endoscopic treatment failure. The possible relationship between the UWT values and other radiological parameter was comparatively evaluated. RESULTS Mean UWT value assessed at the treated stone site was significantly higher in cases unresponsive to endoscopic treatment with values of 2.77 ± 1.03 mm and 4.25 ± 1.32 mm in Group 1 and 2 respectively. A cut off value 3.55 mm for UWT was found to be highly predictive for endoscopic treatment failure. CONCLUSIONS Our current results indicated that assessment of UWT value at the obstructing stone could be helpful enough to predict the likelihood of failure following endoscopic management of strictures with high sensitivity and specificity. Evaluation of this particular parameter could let the endourologists to look for more rational treatment alternatives with necessary measures taken on time.

Abstract
OBJECTIVE To evaluate the outcomes of children with vesicoureteral reflux (VUR) and obstructive megaureter (OM) utilizing various laparoscopic and robot-assisted approaches. MATERIALS AND METHODS Retrospective review of all pediatric laparoscopic and robot-assisted cases for lower ureter pathology was performed between 2016-2022 in 13 academic centers worldwide. Five surgical approaches were assessed: LEUR, LVCUR, LDECUR, RALUR, and RADECUR. RESULTS One thousand three hundred forty-three patients (490 boys and 853 girls) with a median age of 30 months (IQR 12-63) were treated at 13 centers. Nine hundred and eight patients (68%) underwent reimplantation due to VUR (unilateral in 818 and bilateral in 90 patients). Four hundred thirty-five (32%) had a surgery due to ureterovesical junction (UVJ) obstruction. Mean length of follow-up was 14 months (IQR 8-33). Median operative time was 202 minutes (IQR 142-220) in the robotic arm compared to 240 minutes (IQR 160-267) in the laparoscopic (P = .45). Intracorporeal excisional tapering was performed in 118 (8%) of the patients. Six patients in the OM group required additional surgery due to progressive obstruction. In the VUR group, 84% underwent voiding cystourethrography postoperatively. 5.6% showed residual reflux. Grade 1-2 Clavien-Dindo complications occurred in 10 patients (0.7%) and 6 (0.4%) in the laparoscopic and robotic arm, respectively. Grade 3 complications occurred in 17 (1.2%) and 8 (0.5%) in both arms, respectively. Surgical success was achieved in 96% of patients. CONCLUSION Laparoscopic and robot-assisted laparoscopic approaches are simple, safe, and effective for treating all grades of VUR and OM. Robot-assisted approach is beneficial in terms of operative time, intracorporeal suturing, and lower complications rate.

Abstract
INTRODUCTION Ureteropelvic junction obstruction (UPJO) is the most common cause of congenital hydronephrosis. Techniques such as laparoscopic pyeloplasty (LP) have gained in popularity over recent years. Although some retrospective studies have compared minimally invasive reconstructive techniques with open surgery for treatment of UPJO in infants, results remain controversial due to the small sample size in most of these studies. OBJECTIVE To verify whether the benefits of minimally invasive pyeloplasty (MIP) observed in adults and children over 2 years of age also apply to infants. METHODS A systematic review of the literature was performed according to PRISMA recommendations. We searched databases of MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials. We excluded studies in which patient cohorts were outside the age range between 1 and 23 months of age (infants). Studies should evaluate at least one of the following outcomes: average hospital stay, operative time, follow-up time, complications, post-surgical catheter use, success rate and reintervention rate. The quality of the evidence was assessed with the ROBINS-I tool. RESULTS In total, 13 studies were selected. 3494 patients were included in the meta-analysis, of whom 3054 underwent OP, while the remaining 440 were part of the group undergoing MIP. The mean difference in hospital days was -1.16 lower the MIP group (95 % CI; -1.78, -0.53; p = 0.0003). Also, our analysis showed a significantly shorter surgical time in the group who underwent OP, with a mean operative time of 119.92 min, compared to 137.63 min in the MIP group (95 % CI; -31.76, -6.27; p = 0.003). No statistically significant between-group differences were found respect to follow-up time, complications, post-surgical catheter use, success rate and reintervention rate. CONCLUSION This systematic review with meta-analysis has shown that laparoscopic/robotic pyeloplasty in infants is a safe technique with similar success rates to open surgery. Nonetheless, randomized clinical trials with longer follow-up are needed to consolidate these results with more robust scientific evidence.

Abstract
Aims: Retroperitoneoscopic simple nondismembered pyeloplasty (SNDP) with da Vinci Si assistance was developed because of a possible risk for alignment shift after retroperitoneoscopic diamond-shaped bypass pyeloplasty (Diamond-Bypass; DP). Outcomes of SNDP and DP were compared. Materials and Methods: For SNDP, a small longitudinal incision is made on the border of the dilated pelvis and narrowed ureter at the ureteropelvic junction (UPJ). Extending this incision toward the pelvis allows identification of mucosa while maintaining the integrity of surrounding tissues that are so thin and fragile that they will not influence lumen alignment. Data for DP were obtained from a previously published article. Results: For SNDP (n = 3), mean age at surgery was 2.67 years (range: 1-4), mean operative time was 176 minutes. Mean postoperative Society of Fetal Urology (SFU) grades for hydronephrosis were 1.2, 0.7, and 0.6, 1, 2, and 3 months after stent removal, respectively. Postoperative diethylenetriaminepentaacetic acid (DTPA) was normal (n = 3). For DP (n = 5) mean age at surgery was 4.3 years (range: 1-14), mean operative time was 189 minutes. Mean postoperative SFU grades were 2.8, 2.2, and 1.6, respectively. Postoperative DTPA was normal (n = 4) and delayed (n = 1). All SNDP and DP were asymptomatic by 3 months after stent removal. Conclusion: Both SNDP and DP have favorable outcomes. If the UPJ is located at the lowest end of the renal pelvis, SNDP may improve hydronephrosis more quickly.

Abstract
OBJECTIVE To review the management of ovarian cancer (OCa) associated hydronephrosis (HN). Specifically, we aim to identify optimal management of HN in the acute setting, predictors of HN resolution, and the role of surgery (tumor debulking/(+/-)ureterolysis/hysterectomy). MATERIALS/METHODS The study cohort included OCa patients managed at our institution from 2004-2019 that developed OCa-associated HN. Initial HN management was recorded as none, retrograde ureteral stent (RUS) or percutaneous nephrostomy tube (PCN). Primary outcomes included (1) HN management failure, (2) HN management complications, and (3) HN resolution. Patient, cancer, and treatment predictors of outcomes were assessed using logistic regression and fine-Gray competing risk models. RESULTS Of 2580 OCa patients, 190 (7.4%) developed HN. HN was treated in 121; 90 (74.4%) with RUS, 31 (25.6%) with PCN. Complication rates were similar between PCN and RUS (83% vs 85.1%; P = .79; all Clavian Grade I/II). Initial HN treatment failure occurred in 28 patients, predicted by renal atrophy (hazard ratios (HR) 3.27, P <.01). HN resolution occurred in only 52 (27%) patients and was predicted by lower International Federation of Gynecology and Obstetrics (FIGO) stage (FIGO III/IV HR 0.42, P <.01) and surgical tumor debulking/ureterolysis (HR 2.83, P = .02). CONCLUSION Resolution of HN associated with malignant obstruction from OCa is rare and is most closely associated with tumor debulking and International Federation of Gynecology and Obstetrics (FIGO) stage. Initial endoscopic treatment modality was not significantly associated with complications or resolution, though RUS failures were slightly more common. Ureteral reconstruction at time of debulking/ureterolysis is potentially underutilized.

Abstract
PURPOSE To determine if children with UPJO demonstrate a clinically significant change in somatic growth following pyeloplasty. METHODS We retrospectively evaluated the growth chart data of infants with SFU grade 3 or 4 congenital hydronephrosis at our institution from 2015 to 2022. Of those, 35 patients underwent pyeloplasty and 66 had no surgical intervention. Patients met criteria if they had SFU 3 or 4 hydronephrosis and MAG3 renal scan. If patients underwent surgery, height and weight percentiles were recorded from the pre-op and 6-16-month follow-up visits. In non-surgery patients, measurements were taken near the median age of surgery in the intervention group and 6-16 months later. Interval changes in group height and weight percentiles are compared for significant changes. RESULTS The surgery and non-surgery groups did not differ in terms of gender (71% vs 74% Male), starting age (296 vs 244 days), starting weight (58th vs 52nd percentile), or time between measurements (255 vs 260 days), though the surgery group had significantly less height in the pre-operative period (43rd vs 55th percentile, p = 0.050) and were more likely to have delayed drainage on renal scan (83% w/delay vs 35%). The surgery group showed a significant increase in height (18.9 percentiles; 95% CI 11-27) and weight (6.0 percentiles; 95% CI 0.50-12) after intervention. CONCLUSIONS Patients with congenital hydronephrosis due to UPJO that underwent pyeloplasty showed a significant increase in weight and height at 6-16 months postoperatively compared to those that were managed with close observation. This suggests UPJO might lead to growth delay in infants.

Abstract
OBJECTIVE To describe our institution's experience with Boari flap ureteral reconstruction, specifically focusing on the development of postoperative lower urinary tract symptoms (LUTS). METHODS A retrospective review of all Boari flaps performed at our institution between 2013 and 2023 was performed, excluding patients with urothelial carcinoma and males, given the frequency of LUTS from benign prostatic hyperplasia. Primary outcome was the development of new onset LUTS and subsequent treatment. Secondary outcomes included postoperative infections and ureteral stricture. RESULTS Twenty-nine total patients were identified. Mean age was 52.2 years (standard deviation (SD) 13.1). Mean follow-up was 22.3 months (SD 25.3). Primary reasons for ureteral reconstruction were radiation damage (37.9%) and iatrogenic surgical injury (37.9%). A concurrent psoas hitch was performed in 18/29 (62%) cases, nephropexy was utilized in 1/29 (3.4%) cases, and contralateral bladder pedicles were ligated in 10/29 (34.5%) for increased bladder mobilization. Postoperatively, 8 patients (27.6%) developed new-onset LUTS, effectively managed with oral anticholinergics. Recurrent urinary tract infections occurred in 5 patients (17.2%) and pyelonephritis in 1 (3.4%) patient. Two patients (6.9%) developed ureteral strictures, one treated with ileal ureter replacement and the other with ureteral balloon dilation. CONCLUSION Boari bladder flap ureteral reconstruction leads to moderate rates of new onset LUTS postoperatively, which is important information when counseling women on reconstructive options. Boari flap ureteral reconstruction has a high success rate, and serious complications are rare. In the setting of ureteral injury, reconstruction using Boari flaps with or without psoas hitch should be considered for definitive management.

Abstract
INTRODUCTION This case report describes the long-term success of a subcutaneous ureteral bypass device in a dog for treatment of a ureteral obstruction. The suspected xanthine urolithiasis was secondary to treatment with allopurinol for leishmaniasis. The dog presented initially with lethargy, anuria and abdominal pain. Mild azotemia was found on biochemical analysis and abdominal ultrasound revealed bilateral ureteral obstruction. A subcutaneous ureteral bypass was subsequently placed using a standard surgical technique. The dog recovered uneventfully and the azotemia resolved within days. Follow-up examinations were performed every trimester for over three years and no complications like obstruction of the bypass tubes, urinary tract infection or azotemia were recognized during this follow-up period. Allopurinol was replaced with domperidone as long-term treatment against Leishmaniasis which resulted in a mild increase of the leishmania serum antibody titer. The subcutaneous ureteral bypass placement was successful and safe in this dog and is a valuable alternative in cases of ureteral obstruction also in dogs.

Abstract
We began using the da Vinci single port (SP) robot for pediatric urologic surgeries at our institution due to limited access to the multiport robot. Availability of this technology has allowed us to schedule cases in a timelier fashion and increase access to minimally invasive urologic surgery for children in our area. Here, we report our technique for transperitoneal SP robotic pyeloplasty in the case of a 7 year-old boy with left ureteropelvic junction obstruction. Our technique was refined over a series of 10 patients under the age of 18. Highlights of the SP RALP technique include one 3 cm, concealed incision over the pubic tubercle, gentle frog leg positioning and burping of the boom to create optimal angle for robotic docking, and use of a "floating dock" to obtain 10 cm distance from target anatomy which is essential in smaller pediatric patients. SP pyeloplasty is safe and feasible in children and offers a concealed single incision alternative to the multiport approach.

Abstract
PURPOSE To evaluate the rate of and predictors of ureteral obstruction after mini-percutaneous nephrolithotomy (mPCNL) for kidney stones. METHODS We analyzed data from 263 consecutive patients who underwent mPCNL at a single tertiary referral academic between 01/2016 and 11/2022. Patient's demographics, stone characteristics, and operative data were collected. A nephrostomy tube was placed as the only exit strategy in each procedure. On postoperative day 2, an antegrade pyelography was performed to assess ureteral canalization. The nephrostomy tube was removed if ureteral canalization was successful. Descriptive statistics and logistic regression models were used to identify factors associated with a lack of ureteral canalization. RESULTS Overall, median (IQR) age and stone volume were 56 (47-65) years and 1.7 (0.8-4.2) cm3, respectively. Of 263, 55 (20.9%) patients showed ureteral obstruction during pyelography. Patients without ureteral canalization had larger stone volume (p < 0.001), longer operative time (p < 0.01), and higher rate of stones in the renal pelvis (p < 0.01) than those with normal pyelography. Length of stay was longer (p < 0.01), and postoperative complications (p = 0.03) were more frequent in patients without ureteral canalization. Multivariable logistic regression analysis revealed that stone volume (OR 1.1, p = 0.02) and stone located in the renal pelvis (OR 2.2, p = 0.04) were independent predictors of transient ureteral obstruction, after accounting for operative time. CONCLUSION One out of five patients showed transient ureteral obstruction after mPCNL. Patients with a higher stone burden and with stones in the renal pelvis are at higher risk of inadequate ureteral canalization. Internal drainage might be considered in these cases to avoid potential complications.

Abstract
PURPOSE The aim of this study was to present our initial experience and prove the feasibility of total intracorporeal laparoscopic ileal ureter replacement (TILIUR) in a single position for ureteral stricture based on membrane anatomy. MATERIALS AND METHODS Between January 2021 and April 2023, six patients underwent TILIUR in a single position for ureteral strictures based on membrane anatomy. All patients with a past medical history underwent radical hysterectomy with bilateral pelvic lymph node dissection as well as extensive ureteral stricture due to radiotherapy. The procedure is performed completely laparoscopically. Dissection of the digestive system as well as ureteral stricture or renal pelvis is based on membrane anatomy. The surgery is performed in a single position. RESULTS TILIUR in a single position for ureteral stricture based on membrane anatomy was successfully performed without open conversion in all patients. Among the 6 patients, 3 patients underwent combined ileal ureter replacement (IUR) and abdominal wall ostomy, 2 underwent unilateral IUR, and 1 underwent bilateral IUR. The mean length of the ileal substitution was 22.83 cm (range: 15-28). The average operative time was 458 ± 72.77 min (range 385-575 min), and the average intraoperative blood loss was 158 mL (range 50-400 mL). The median postoperative hospital stay was 15.1 d (range: 8-32). The median duration of postoperative follow-up was 15 months (range: 3-29 months). The success rate was 100%. CONCLUSIONS TILIUR in a single position may be a promising option for ureteral stricture based on membrane anatomy in selected patients. Moreover, it has a positive effect on patients with renal insufficiency and urinary incontinence. Although IUR is difficult and risky, proficient surgeons can perform the procedure safely and effectively.

Abstract
To the Editor, Pelvi-ureteric junction obstruction (PUJO) is a well-recognised clinical entity characterised by functionally significant impairment of drainage of urine at the level of the pelvi-ureteric junction due to extrinsic or intrinsic obstruction and is encountered both by adult and paediatric urologists alike. Management of PUJO has been surgical historically, and the gold standard has been an open Anderson-Hynes dismembered pyeloplasty [...].

Abstract
Purpose: To evaluate functional outcomes of robot-assisted ureteroplasty with labial mucosa grafting for long proximal ureteral stenosis (LPUS) in children and adolescents. Methods: Included in this study were 15 patients who underwent robot-assisted ureteroplasty with labial mucosal grafting in our center between July 2017 and September 2021. The left affected stenotic ureter was repaired using labial mucosal grafting. If the ureter was simply strictured but not obliterated, the ureter was spatulated longitudinally along the ventral side and the labial mucosa graft was interposed and anastomosed in a continuous manner. Faced with the obliterated segment, it was excised and the spatulated portion re-anastomosed with a pelvic flap as the dorsal wall. The labial mucosa graft was placed as the ventral wall. The preoperative clinical data and follow-up outcomes were collected and evaluated. Results: Labial mucosa graft onlay ureteroplasty was well performed in all the 15 patients with no occurrence of intraoperative complications or surgical conversion. Five patients underwent an onlay ureteroplasty, and 10 patients underwent a dorsally augmented pelvic flap anastomotic ureteroplasty. The mean (range) stricture length was 7.1 (3-10) cm. The mean operative time was 371.2 (216-480) minutes, and the median blood loss was 40 mL. At the median follow-up of 35 months (range 12-58 months), the overall success rate was 93.3%. Conclusions: Labial mucosa grafting appears to be safe and feasible for repairing long ureteral strictures in pediatric and adolescent patients. Our experience may provide beneficial references and conveniences to solve complex problems in LPUS. This study was approved by the institutional review board, and written informed consent was obtained from each participant (ethics number: 2017-30).

Abstract
PURPOSE OF REVIEW This review aims to provide an in-depth exploration of the recent advancements in robot-assisted laparoscopic pyeloplasty (RALP) and its evolving landscape in the context of infant pyeloplasty, complex genitourinary (GU) anatomy, recurrent ureteropelvic junction (UPJ) obstruction, cost considerations, and the learning curve. RECENT FINDINGS Recent literature highlights the safety and efficacy of RALP in treating the infant population, patients with complex GU anomalies, and recurrent UPJO which were all traditionally managed using the open approach. Cost considerations are evolving, with the potential for RALP to have a lesser financial burden. In addition, the learning curve for RALP is diminishing due to robust training programs and advances in research. RALP has become the gold standard in the treatment of UPJO in pediatric urology at many children's hospitals. Surgeon comfort and research in this space allow safe and successful reconstruction in the most challenging of cases.

Abstract
Purpose: To analyze the utility and outcomes of available endourologic options to treat ureteral stricture after kidney transplantation (KT). Methods: A systematic review was carried out for all English language articles from 2000 to 2023 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) standards using EMBASE, MEDLINE, SCOPUS, Google scholar, and Cochrane library. The search term combination for the string was follows: [(Ureteral stricture) OR (ureter stenosis) OR (ureteral stenosis) OR (Stricture ureter) OR (Narrowing ureter) OR (Ureter restriction) OR (ureteral restriction) OR (ureteral narrowing) OR (ureteral obstruction) OR (ureter obstruction) OR (obstructing ureter) OR (obstructive ureter) OR (narrow ureter) OR (ureteral narrow)] AND [(kidney transplant) OR (transplanted kidney) OR (transplant) OR (transplantation)] AND [(management) OR (Robotic) OR (laser) OR (stent) OR (dilatation) OR (dilation) OR (endoscopic) OR (endourological) OR (Urologic) OR (laparoscopic) OR (surgery) OR (treatment)]. Case reports, review articles, animal and laboratory studies were excluded. Risk of bias assessment was conducted using the RoB 2 and ROBINS-I tools. Results: A total of 1102 relevant articles published from 2000 to 2023 were found. After screening of titles and abstracts, a total of 19 articles were included in our systematic review. Ureteral stent/nephrostomy placement, balloon dilatation (ureteroplasty) with or without laser was used as initial approaches whereas follow-up and success rate were analyzed among other parameters. Conclusions: The management of ureteral strictures after KT is challenging and selecting the most appropriate treatment is crucial for successful outcomes. Our review suggests that, an endourologic management is a safe option with good long-term outcomes, especially in short and early strictures.

Abstract
PURPOSE To investigate the feasibility, safety, and effectiveness of magnetic compression anastomosis of benign short-segment ureteral obstruction. MATERIALS AND METHODS Patients referred for failure of ureteral double-J stent placement because of impassable benign ureteral obstruction were included. Eleven patients (11 ureters) with a mean age of 57.5 years (range, 19-85 years; 8 women) underwent ureteral magnetic compression anastomosis. All patients had indwelling nephrostomy catheters. In all patients, anterograde and retrograde ureteral stent placements were unsuccessful using either interventional or cystoscopic access. Ureteral magnetic compression anastomosis was performed as a 2-step procedure. In the first step, magnets were placed. In the second step, the stricture was traversed via magnetic compression anastomosis. Successful establishment of anastomosis and ureteral double-J stent placement were considered technical success. The mean time for complete magnetic adherence and fluoroscopy time for each procedure were recorded. RESULTS Five patients (45%) had an ileal conduit. The technical success rate was 91% (n = 10/11). The mean time for magnetic adherence was 5.7 days (SD ± 1.3). The mean single-rotation fluoroscopy times during the first and second steps of the procedure were 9.45 minutes (SD ± 2.09) and 15.70 minutes (SD ± 2.62), respectively. Magnets were removed with the support of either balloon catheters (n = 9) or biopsy forceps (n = 2). No procedure-related adverse events occurred. CONCLUSIONS Magnetic compression anastomosis of benign ureteral obstruction is feasible and safe and can be performed in an interventional radiology (IR) suite without the need for endoscopy.

Abstract
OBJECTIVE To retrospectively compare the differences in the surgical efficacy and prognosis of laparoscopic pyeloplasty for hydronephrosis caused by symptomatic versus asymptomatic ureteropelvic junction obstruction (UPJO) in children and determine whether clinical symptoms affect the surgical outcome and prognosis. METHODS Children who underwent laparoscopic pyeloplasty in our hospital from January 2018 to December 2022 were retrospectively analyzed. The children were divided into symptomatic and asymptomatic groups according to their main symptoms. The primary outcomes were the surgical success rate, change in renal parenchymal thickness, and change in renal pelvis anteroposterior diameter. The secondary outcomes were postoperative complications, reoperation rate, operative duration, intraoperative blood loss, and drainage tube indwelling time. RESULTS In total, 224 children with UPJO were enrolled; 148 (66.1%) were symptomatic and 76 (33.9%) were asymptomatic. The symptomatic group showed a significantly greater mean change in renal parenchymal thickness, significantly higher surgical success rate, and significantly lower postoperative complication rate. CONCLUSIONS In the present study, asymptomatic children had a lower surgical success rate, less postoperative imaging improvement, and more postoperative complications than symptomatic children. The presence or absence of clinical symptoms may affect the surgical outcome and prognosis.

Abstract
Purpose: To evaluate the safety and feasibility of lingual mucosal graft ureteroplasty (LMGU) combined with ureteral reimplantation (UR) for repairing managing multifocal ureteral strictures (MUS). Methods: Between December 2020 and December 2022, 14 patients underwent LMGU combined with UR. Their perioperative data were collected retrospectively and analyzed. For the proximal diseased ureter, the narrow segment was incised longitudinally to open the ventral wall of ureter, and a lingual mucosal graft was placed as an onlay graft. Meanwhile, UR was applied to treat distal ureteral strictures. Results: Of 14 patients, three (21.4%) had previously undergone a failed ureteral reconstruction. The mean (standard deviation [SD]) proximal stricture length was 4.0 cm (1.56), and distal ureteral stricture length was 4.3 cm (0.94). The mean (SD) operative time was 236 minutes (57), the estimated blood loss was 78 mL (41.5), and the length of postoperative stay was 6 days. One (7%) patient underwent double LMGU to treat proximal 2 segments of ureteral stricture. No open conversions and intraoperative complications occurred. With a mean follow-up of 15 months (range 6-29), the recurrence-free rate was 14/14 (100%). Conclusions: LMGU combined with UR is a feasible and effective technique for managing MUS and can be an alternative to ileal ureteral replacement or renal autotransplantation in some selected patients with MUS.

Abstract
Objective: The aim of this study is to assess the efficacy and safety of laparoscopic surgery in the treatment of pediatric ureteral fibroepithelial polyp (FEP) patients. Our hypothesis is that laparoscopic surgery can effectively treat FEPs while minimizing patient discomfort and complications. Our research aims to evaluate the clinical outcomes of the surgery, including postoperative symptom relief, improvement in kidney function, and risk of postoperative complications. Methods: The clinical records of 34 patients who underwent ureteral polyp surgery at the Department of Urology at Anhui Provincial Children's Hospital between May 2014 and February 2023 were retrospectively analyzed. All patients underwent laparoscopic surgery. Among the 34 pediatric patients, there were 31 males and 3 females, with 2 on the right side and 32 on the left side. Of these cases, 24 polyps were located at the ureteropelvic junction, while seven were found in the upper segment of the ureter and three in its middle segment. Patients' ages ranged from 4 years and 3 months to 15 years, with a median age of 8 years and 6 months. All children presented with varying degrees of hydronephrosis, and preoperative clinical symptoms included ipsilateral flank or abdominal pain, hematuria, and other discomfort. Preoperative examinations mainly comprised ultrasound, intravenous pyelography, CT, or magnetic resonance urography imaging studies, as well as diuretic renography. All pediatric patients underwent laparoscopic excision of the polyp segment of the ureter, followed by renal pelvis ureteroplasty or ureter-to-ureter anastomosis. Results: All patients underwent surgery without conversion to open surgery. The surgical duration ranged from 72 to 313 minutes, with an average of 179.5 minutes. The average intraoperative blood loss was 14 mL. Postoperatively, one patient experienced leakage at the anastomotic site; however, no other significant complications occurred during or after the procedure. Postoperative histopathology confirmed the presence of FEPs in the ureter for all cases. All patients experienced a favorable postoperative recovery, with hospitalization periods ranging from 3 to 16 days and an average stay of 8.6 days. A Double-J stent was inserted in all patients for a duration of 1 to 2 months after surgery, and upon removal, follow-up color Doppler ultrasound revealed reduced hydronephrosis within 1 to 3 months. Follow-up examinations were conducted at intervals ranging from 3 to 108 months postsurgery, with an average follow-up time of 42.2 months, during which no recurrence of ureteral polyps or symptoms such as pain and hematuria was observed. Conclusions: The findings of this study demonstrate that laparoscopic excision of the polyp segment of the ureter, renal pelvis ureteroplasty, and ureter-to-ureter anastomosis represent safe and effective treatment modalities for pediatric FEPs in the ureters. This technique offers several advantages, including minimal invasiveness, rapid recovery, and definitive therapeutic efficacy, which effectively alleviate clinical symptoms and improve hydronephrosis.

Abstract
PURPOSE To investigate the effect of pyeloplasty in pediatric patients with poor function kidneys, focusing on the split renal function (SRF) and anteroposterior diameter (APD) of the renal pelvis. MATERIALS AND METHODS A retrospective study included 47 pediatric patients with ureteropelvic junction obstruction (UPJO) who underwent open pyeloplasty with SRF< 20%. All patients were recruited from the Labbafinejad University Hospital center from April 2014 to October 2020. The results of preoperative ultrasonography and Diethylenetriamine pentaacetate (DTPA) scan compared with the results of the ultrasonography and DTPA scan 6 months and one year after surgery. Finally, Wilcoxon signed-rank test was used to test differences the SPSS (version 25) software statistical computer package. RESULTS The mean age of participants was 1.5 years. There were 34 cases with SRF between 10% and 20%, and 13 cases with SRF < 10%. The findings showed that pyeloplasty for UPJO leads to a significant improvement in renal function in poorly functioning renal units with 10% ≤ SRF < 20%. Although improvement in renal function occurred in the group with SRF of less than 10%, it was not statistically significant. The APD in both groups was statistically significantly improved. No correlation between genders and outcomes was found. CONCLUSION Poorly functioning renal unit (SRF < 20%) can show functional improvement after the pyeloplasty.

Abstract
Cystectomy is the gold standard treatment for muscle invasive bladder cancer. Robotic cystectomy has become increasingly popular owing to quicker post- operative recovery, less blood loss and less post-operative pain. Urinary diversion is increasingly being performed with an intracorporeal technique. Uretero-enteric strictures (UES) cause significant morbidity for patients. UES for open cystectomy is 3-10%, but the range is much wider (0-25%) for robotic surgery. We aim to perform systematic review for studies comparing all 3 techniques, to assess for ureteric stricture rates. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement (Page et al. in BMJ 29, 2021). PubMed, Scopus and Embase databases were searched for the period January 2003 to June 2023 inclusive for relevant publications.The primary outcome was to identify ureteric stricture rates for studies comparing open cystectomy and urinary diversion, robotic cystectomy with extracorporeal urinary diversion (ECUD) and robotic cystectomy with intracorporeal urinary diversion (ICUD). Three studies were identified and included 2185 patients in total. The open operation had the lowest stricture rate (9.6%), compared to ECUD (12.4%) and ICUD (15%). ICUD had the longest time to stricture (7.55 months), ECUD (4.85 months) and the open operation (4.75 months). Open operation had the shortest operating time. The Bricker anastomoses was the most popular technique. Open surgery has the lowest rates of UES compared to both robotic operations. There is a learning curve involved with performing robotic cystectomy and urinary diversion, this may need to be considered to decide whether the technique is comparable with open cystectomy UES rates. Further research, including Randomised Control Trials (RCT), needs to be undertaken to determine the best surgical option for patients to minimise risks of UES.

Abstract
To explore the learning curve of robot-assisted laparoscopic pyeloplasty (RALP) in children. The clinical data, surgical information, and postoperative complications of consecutive cases of RALP performed by the same surgeon in Shanghai Children's Hospital from January 2014 to July 2020 were retrospectively analyzed; the surgeon is a senior pediatric urologists who is proficient in laparoscopic pyeloplasty; the data consist of console time (CT), suture method when anastomosing ureteropelvic junction (UPJ), number of stitches (N), anastomosis time per stitch (tn), the average suture time per stitch (T) = (suture time of first stitch (t1) + second stitch (t2) + … + tn)/N, postoperative complications, and surgical outcome. The learning curve was depicted by cumulative sum method (CUSUM) and validated by cumulative method (CUM). Of the 88 cases, 64 cases were included in present study. Median CT was 104 (83-117) min, mean T was 109 ± 17 s. There were ten cases of Clavien-Dindo Grade I complication and two cases of Clavien-Dindo Grade IIIb complication. The median follow-up time was 237 (87-627) days. The learning curve of CT has three stages, with inflection points at 11th and 57th case, and T has two stages, with inflection points at 19th case. There was a statistically significant difference between the console time and length of stay on both sides of the inflection point (P < 0.05), but there was no statistically significant difference in age, gender, etiology, clinical manifestation, surgical outcome, and complication (P > 0.05). For a senior pediatric urologists who is proficient in laparoscopic pyeloplasty, the learning curve of RALP can be divided into three stages, preliminary exploration stage, mastery stage, and proficiency stage. It takes about 11 cases to achieve the mastery stage, and it takes about 57 cases to achieve the proficiency stage. The learning curve focused on the suture technique of the surgeon is divided into two stages, and after a learning period of 19 cases, it will reach the proficiency stage of suturing UPJ.

Abstract
PURPOSE Malignant ureteric obstruction is a significant management challenge. The failure of ureteric stents often leads to long-term nephrostomy tubes. This is delayed for as long as possible due to its' associated morbidity. Several types of ureteric stents are available, however there is little evidence demonstrating which stents are better for preventing progression to nephrostomy tubes. This study looked to determine whether a new 6 French (Fr) polymer stent, 8Fr polymer stent or metallic stent achieved a longer functional duration once the initial polymer ureteric stent failed. METHODS A retrospective, longitudinal study was performed at a single tertiary institution. All patients who underwent ureteric stenting with a 6Fr polymer stent for malignancy between 2010 and 2020 were included. Patients were followed up until death with ureteric stent in situ or permanent nephrostomy tube insertion. RESULTS A total of 46 patients (66 ureters) had ureteric stents inserted for malignancy. From initial ureteric stent failure, 10 stents were changed to a new 6Fr polymer stent, 42 were changed to an 8Fr polymer stent and 14 were changed to a Resonance® 6Fr metallic stent. The Resonance 6Fr metallic stent had the longest median functional duration of 14 months (p = 0.012). CONCLUSION Resonance® 6Fr metallic stents appear to have a significantly longer functional duration than a new 6Fr polymer stent or 8Fr polymer stent, which may allow patients to enjoy a better quality of life and delay permanent nephrostomy tube insertion.

Abstract
Ureteral involvement by a tumor is common, and both partial and complete obstructions can result in symptoms that are distressing and debilitating, especially in cancer patients for whom the resection of the primary tumor is not considered an option. Maintaining ureteric patency in these patients is a challenge. In addition, in cases where a patient has undergone nephroureterectomy due to primary transitional cell cancer, it becomes necessary to decompress the urinary tract to preserve the contralateral kidney from irreversible damage. This is possibly due to ureteral stenting, both retrograde and anterograde, and percutaneous nephrostomy (PCN). Since imaging plays an important role in the routine monitoring of stents, their more and more increasing use requires radiologists to be familiar with these devices, their correct position, their potential complications, and their consequences. The aim of this review is to offer a comprehensive review of the imaging features of some urinary stents and to show the complications encountered in cancer patients as a direct consequence of an invasive diagnostic or therapeutic procedure. Specifically, we focus on ureteral stents and PCN.

Abstract
Ureteral endometriosis is rare and can be a silent clinical entity, which can potentially lead to serious complications such as obstructive uropathy, sepsis and renal failure. A high clinical suspicion is required especially in childbearing age groups due to non-specific presentation such as renal colic, recurrent urinary tract infection (UTI), renal failure or asymptomatic hydronephrosis.A woman in her 40s presented with febrile UTI and flank pain. She reportedly suffered from recurrent UTIs in the past. Initial workup revealed an infected, obstructed left renal collecting system with gross hydronephrosis and hydroureter to the distal ureter on a significant gynaecological background of severe endometriosis requiring hysterectomy in the past.CT showed chronic obstructive changes and soft tissue nodules within the renal pelvis with no radio-opaque stones. She underwent emergent ureteric stent insertion. Functional imaging demonstrated only 1% contribution of the left kidney with a preserved estimated glomerular filtration rate of 65 mL/min/1.73 m2Endoscopic evaluation of ureters found extensive soft tissue lesions throughout the dilated left collecting system with biopsy-confirmed endometriosis. Subsequently, she underwent laparoscopic nephroureterectomy due to extensive ureteric involvement and chronically obstructed non-functioning kidney. Histopathology demonstrated completely obstructing ureteral endometriosis.Ureteric obstruction secondary to endometriosis can be due to extrinsic or intrinsic disease. In addition to initial assessment with CT urogram MRI may be helpful to evaluate soft tissue thickening. Endoscopic assessment with ureteroscopy and biopsy is required for tissue diagnosis. Surgery is often the treatment of choice, ranging from ureteroureterostomy, ureteroneocystostomy or nephroureterectomy in severe cases.Ureteral endometriosis is a rare clinical entity, clinicians should remain vigilant about common presentations of this rare entity, early diagnosis and prompt treatment is crucial to prevent progression to renal failure.

Abstract
INTRODUCTION AND OBJECTIVE Ureteral reimplantation of the dilated ureter in infants is challenging; however, some patients with primary obstructive megaureter (POM) in this age group require intervention due to clinical or radiological progression. We sought to determine if high pressure balloon dilation (HPBD) can serve as a definitive treatment for POM in children under one year of age, or as a temporizing measure until later reimplantation. MATERIALS AND METHODS All patients from a single institution who underwent HPBD between October 2009 and May 2022 were retrospectively reviewed. Patients were excluded if older than 12 months or diagnosed with neurogenic bladder, posterior urethral valves, or obstructed refluxing megaureter. Patients with prior surgical intervention at the ureterovesical junction were excluded. Indications for surgery included progressive hydroureteronephrosis or urinary tract infection (UTI). Balloon dilation was performed via cystoscopy with fluoroscopic guidance, followed by placement of two temporary ureteral stents. Primary outcomes were improvement or resolution of megaureter and rates of subsequent reimplantation. Secondary outcomes included total number of anesthetics and postoperative UTIs. RESULTS Fifteen infants with median age of 7.6 months (IQR 3.8-9.7) underwent HPBD. Twelve (80%) patients were detected prenatally and 3 (20%) after a UTI. Indication for surgery was progressive hydroureteronephrosis in 10 patients (67%) and UTI in five (33%). All had SFU grade 3 or 4 hydronephrosis on preoperative ultrasound and median distal ureteral diameter was 13 mm. Median follow up was 2.9 years. Twelve (80%) succeeded with endoscopic treatment: 7 patients had an undetectable distal ureter on ultrasound at last follow-up, 5 were improved with median distal ureteral diameter of 7 mm. Three patients (20%) required ureteral reimplantation due to progressive dilation, all with grade 4 hydronephrosis and distal ureteral diameters were 11, 15, and 21 mm. Six patients (40%) required two anesthetics to complete endoscopic treatment. Among those, 4 patients required initial stent placement for passive dilation followed by a second anesthetic for HPBD weeks later. Two patients underwent repeat HPBD following postoperative proximal migration of the ureteral stents. All 15 patients had an additional anesthetic for removal of stents. Five patients (33%) were treated for a symptomatic UTI (4 febrile, 1 afebrile) with the stents indwelling but there were no UTIs in the group following stent removal. CONCLUSION Balloon dilation is a practical option for treatment of POM in infants, and in most cases (80%) avoids subsequent open surgery (over median 2.9 years of follow-up).

BACKGROUND The aim of this study was to explore the feasibility of ileal ureter replacement and ileocystoplasty for the treatment of bilateral long-segment ureteral strictures combined with bladder contracture. METHODS A retrospective review of clinical data from seven patients who underwent bilateral Ileal Ureter Replacement and ileocystoplasty from April 2019 to February 2023 was conducted. The surgeries were performed using open, laparoscopic, and robot-assisted laparoscopic approaches. Baseline characteristics, perioperative, and mid-term results of the patients were collected. Follow-up period of 3-28 months. A detailed description of the technique was reported. RESULTS The mean age of the patients was 52.86±6.06 years. The average duration of surgery was 365±28.54 minutes, and the estimated intraoperative blood loss was 357.14±184.06 mL. The mean length of harvested ileum was 37.86±8.40 cm. The preoperative serum creatinine level was 88.02±18.05 μmol/L, postoperative day 1 creatinine level was 90.7±12.93μmol/L, postoperative 3-month creatinine level was 93.77±33.34 μmol/L, and the mean creatinine level at the last follow-up was 94.89±27.89μmol/L. The postoperative bladder capacity was 249.43±32.50 mL on average. The average length of hospital stay was 26.57±15.46 days. No complications of Clavien-Dindo grade 3 or higher were observed. During the follow-up period, no patients experienced deterioration of renal function after surgery. CONCLUSIONS Bilateral ileal ureter replacement and ileocystoplasty are effective surgical technique for the treatment of bilateral long-segment ureteral strictures combined with bladder contracture caused by radiation therapy.

Abstract
A 3.5-year-old intact male Labrador retriever was seen for hematuria. The results of clinical pathology tests were unremarkable. However, urinalysis revealed dark, cloudy, alkalotic, and isosthenuric urine containing red and white blood cells, epithelial cells, and struvite crystals. Severe bilateral enlargement of ureters and markedly enlarged kidneys were identified on abdominal radiographs. Computerized tomography revealed extensive bilateral hydroureteronephrosis with no definitive cause of obstruction. The dog underwent bilateral ureteral tapering with bilateral neoureterocystostomy and placement of temporary bilateral ureteral stents and a cystostomy tube. The dog was monitored in the intensive care unit for 7 d after surgery and was discharged 9 d after surgery and after the stent and cystostomy tube were removed. The dog remained clinically normal and was reported to have been euthanized at 11 y of age (2021) due to unspecified causes. Key clinical message: There are several potential causes of severe bilateral hydroureteronephrosis in animals. Based on this case report, dogs with severe bilateral hydroureteronephrosis that are clinically asymptomatic may have favorable outcomes following bilateral ureteral reconstruction and neoureterocystostomy, even if a definitive cause is not identified.

Abstract
OBJECTIVE To investigate predictors of surgical success for patients undergoing robotic ureteral reconstruction (RUR) for ureteropelvic junction obstruction (UPJO), proximal, and middle ureteral stricture disease. METHODS We retrospectively reviewed our multi-institutional Collaborative of Reconstructive Robotic Ureteral Surgery database to identify all consecutive patients undergoing RUR for UPJO, proximal and/or middle ureteral stricture disease between April 2012 and December 2020. The specific reconstruction technique was determined by the primary surgeon based on clinical history and intraoperative findings. Patients were grouped according to whether they were surgical successful. Preoperative variables between both groups were compared using chi-square tests. All independent variables with associations of P <.2 then underwent a binary logistic regression analysis to determine predictive variables of success for RUR (P ≤.05 was considered statistically significant). RESULTS Overall, 338 patients met inclusion criteria. Surgical success rates of RUR are shown in Table 1. Univariate analysis (Table 2) showed that there were a lower proportion of patients with diabetes (8.9% vs 25.7%, P <.01) and a higher proportion of patients who underwent ureteral rest (74.3% vs 48.6%, P <.01) in the surgical success group. Multivariate logistic regression analysis (Table 3) further revealed the odds of surgical success in patients without diabetes was 3.08 times ((confidence interval) CI 1.26-7.54, P = .01) the odds of success for patients with diabetes. The odds of surgical success in patients who underwent preoperative ureteral rest were 2.8 times (CI 1.35-5.83, P = .01) the odds of success for patients who did not undergo preoperative ureteral rest. CONCLUSION Surgical success of RUR for management of UPJO, proximal, and middle ureteral strictures may be influenced by factors including preoperative ureteral rest and presence of diabetes.

Abstract
BACKGROUND The management of UPJO with poor function kidney, less than 10%, has been the subject of debate for more than a decade. Some authors have recommended nephrectomy, while others favor renal salvage (pyeloplasty). We report our experience with laparoscopic assisted pyeloplasty in pediatric patients with poorly functioning kidneys in comparison with an open approach. MATERIALS AND METHODS A retrospective study was conducted to review 65 patients who were diagnosed with hydronephrosis and had impaired renal function due to UPJO. The study was conducted in the pediatric surgery departments of Al-Azhar University Hospital and Fattouma Bourguiba University Hospital of Monastir over a period of 20 years. Limited to pediatric patients with UPJO with ≥ Grade III hydronephrosis, antero-posterior pelvic diameter ≥ 20 mm, as well as a renal function equal to or less than 10%, was corrected by laparoscopic assisted or open pyeloplasty. RESULTS There were 40 cases in group A who underwent laparoscopic assisted pyeloplasty, and 25 cases in group B who underwent open pyeloplasty. There were no complications or difficulties during the operation. The mean operative time in group A was 90 ± 12 min, while in group B, it was 120 ± 11 min. The renal assessment parameters significantly improved in both groups. In group A, the mean split renal function was 7.9 ± 1.3% and increased to 22.2 ± 6.3%. In group B, the mean split renal function was 8.1 ± 1.1% and increased to 24.2 ± 5.1%. However, the differences between both groups in terms of pre-operative and post-operative renal functions were statistically insignificant. CONCLUSION Laparoscopic assisted pyeloplasty is an effective treatment for patients with poorly functioning kidneys, especially those with less than 10% function. While this surgical procedure requires shorter operative times, it yields functional outcomes that are comparable to open approach.

Abstract
INTRODUCTION The role of voiding cystourethrogram (VCUG) in evaluating vesicoureteral reflux (VUR) in patients with known ureteropelvic junction obstruction (UPJO) remains unclear. While VCUG is frequently performed, the incidence of concomitant VUR and UPJO is low, and VUR is often low-grade with high rates of spontaneous regression. OBJECTIVE To analyze the clinical relevance of VCUG in patients with UPJO by determining its incidence and studying the difference in clinical outcomes between patients with known, unknown, and negative VUR. STUDY DESIGN Retrospective review of patients with UPJO who underwent pyeloplasty from 2012 to 2020 with <18 years-old, unilateral UPJO, postoperative follow-up of ≥2 months and had at least 1 renal ultrasound (US) after pyeloplasty. Results were compared among 3 groups: patients who underwent VCUG before pyeloplasty and were found to have VUR (group 1), patients who underwent VCUG before pyeloplasty without VUR (group 2), and patients who did not have a VCUG before pyeloplasty (group 3). RESULTS A total of 275 patients met the inclusion criteria, of which 21 patients were classified in group 1, 166 patients in group 2, and 88 patients in group 3 (Table). The age at preoperative VCUG was 14.7 ± 32.9 months in group 1 and 15.17 ± 35.8 months in group 2 (p = 0.960). Overall, the incidence of concomitant UPJO and VUR was 11.2%. In group 1 the initial VUR grade was 5 in 2 patients, 4 in 3, 3 in 5, 2 in 7, and 1 in 4 patients. Of these, only 1 patient required ureteral reimplantation after pyeloplasty. Post-pyeloplasty, no significant differences were observed in complications (p = 0.7436), length of follow up (p = 0.3212), SFU grade 4 hydronephrosis (p = 0.2247), postoperative UTIs (p = 0.1047) and pyeloplasty success rate (p = 0.4206) among the 3 groups. Despite the use of antibiotic prophylaxis being significantly different amongst the three groups (p < 0.001), it was not associated with a lower incidence of postoperative UTIs (group 1 p = 0.068, group 2 p = 0.486, group 3 p = 1). In patients with reflux, an increase in age was associated with a decrease in the rates of complications (p = 0.019). CONCLUSION We found no significant difference in the outcomes in patients who had a preoperative VCUG as compared to those who did not. The preoperative diagnosis of VUR by VCUG changed the management in less than 1% of the study population and thus its role in patients with UPJO should be reevaluated.

Abstract
BACKGROUND Erdheim-Chester disease (ECD) is a rare progressive non-Langerhans' cell histiocytic multisystem disorder with a broad spectrum of clinical manifestations, including infiltrative perinephric with ureteral involvement resulting in hydronephrosis, renal atrophy, and eventual renal failure. OBJECTIVE To present a patient with ECD with bilateral renal/ureteral involvement managed with bilateral percutaneous nephrostomy tubes (PCNT) and trametinib who underwent bilateral robotic upper tract reconstruction, the first such published report. The video demonstrates only the left-sided repair, which posed specific challenges and demonstrates reconstructive techniques useful in complex upper tract repairs with limited tissue availability. MATERIALS AND METHODS A 35-year-old male initially presented with baseline creatinine of 1.62 and split renal function; 30% right and 70% left by Lasix renogram. Extra-genitourinary manifestations of disease included cardiac hypertrophy and skin ulcers/lesions. Bilateral retrograde pyeloureterography showed proximal ureteral obliteration ∼4 cm bilaterally. Multiple management options were discussed including PCNTs, but patient elected for definitive repair. He was seen by Cardiology and Anesthesia and deemed to be optimized. He held his trametinib for 1week before surgery. We demonstrate a difficult ureteral dissection with fibrotic hilum preventing separation. Simultaneous ureteroscopy identified the distal extent of stricture which was excised, leaving a ∼15 cm gap. Downward nephropexy was performed with ultrasound guidance to identify an inferior calyx. Partial nephrectomy was then performed without vascular control due to hilar fibrosis. Ileal interposition was chosen to bridge the remaining ∼8 cm gap. Proximal ileo-calyceal and distal ileo-ureteral anastomoses were performed. We then placed a 30 cm × 7 Fr double-J ureteral stent in standard fashion. The ileum was secured to the renal pelvis to maintain a straight lie and an omental flap was secured in place. RESULTS Immediate postoperative course was complicated by partial small bowel obstruction leading to a negative exploratory laparotomy and a subsequent episode of urosepsis. The patient is now voiding well without stents or PCNTs, without infections and with improving renal function, now with GFR (glomerular filtration rate) of 62 from 43 preoperatively. With aggressive hydration, patient has had no obstruction of the distal ureter with mucus. MRI Abdomen/Pelvis 6months later showed irregularity of the calyces with stable mild hydronephrosis. The patient continues to be medically managed on trametinib for his underlying disease, with surveillance for recurrent fibrosis and obstruction which has not yet occurred. CONCLUSION Robotic ureterolysis and ureterocalycostomy with possible bowel interposition is a reasonable option for upper tract reconstruction in select patients with ECD.

Abstract
Purpose: Spatulation during ureteropelvic junction obstruction repair was evaluated in children treated by robot-assisted retroperitoneal pyeloplasty anastomosis (RRPA). Methods: Intraoperative video recordings (IVRs) of RRPA (n = 22 ureters) performed at a single institute between 2018 and 2022 were reviewed blindly by 5 independent surgeons for perceived difficulty of suturing (DOS; 5 = impossible; 4 = difficult; 3 = tedious; 2 = slow; 1 = easy) and spatulation ranking as superior (+1), inferior (-1), or unnecessary (0). The retroperitoneal space was accessed in the lateral decubitus position using a closed technique under direct vision to avoid air leakage and subcutaneous emphysema. All subjects had a Double-J stent (4.7F) placed. Results: Subjects had similar demographics and preoperative ureter diameters. IVRs were RRPA with spatulation of the ureter on the lateral side (RRPA +SP) (n = 13) and RRPA without spatulation of the ureter (RRPA -SP) (n = 9). Overall DOS scores and coefficients of variation for time taken to place one suture were similar. Total anastomotic time was significantly shorter for RRPA -SP; 67.9 ± 8.4 minutes versus 57.9 ± 9.2 minutes, P = .01. Overall spatulation ranking was 0. Postoperative scanning showed improved drainage in 12 of 13 (92%) in RRPA +SP and 8 of 9 (88%) in RRPA -SP; differences were not significant. One anastomotic stricture in RRPA -SP required open repair. Conclusions: RRPA was quicker and more precise without spatulation. Outcomes of scanning 1 year after RRPA were similar for RRPA -SP and RRPA +SP.

Abstract
INTRODUCTION Historically, ureteral reimplantation (UR) has been the gold standard for treatment of primary obstructive megaureter (POM) with declining renal function, worsening obstruction, or recurrent urinary tract infections. In infants, open surgery with reimplantation of a grossly dilated ureter into a small bladder, can be technically challenging with significant morbidity. Therefore, less invasive endoscopic management such as dilatation or incision of the ureter-vesical junction, has emerged as an alternative to reimplantation during the last decades. OBJECTIVE To systematically evaluate the effectivity, safety, and potential benefits of endoscopic treatment (dilatation with or without balloon or incision) of POM in comparison to UR. STUDY DESIGN A systematic review was conducted. Randomized controlled trials (RCTs), nonrandomized comparative studies (NRSs), and single-arm case series including a minimum of 20 participants and a mean follow-up more than 12 months were eligible for inclusion. RESULTS Of 504 articles identified, 8 articles including 338 patients were eligible for inclusion (0 RCTs, 1 NRSs, and 7 case series). Age at time of surgery was minimum 15 days to a maximum of 192 months. Indications for endoscopic treatment (ET) included patients with loss of split renal function (>10%) and worsening of hydroureteronephrosis. The studies analysed reported a success rate ranging from 35% to 97%. Success was defined as stabilization of differential renal function without further procedures. A post-operative complication rate of 23-60% was reported (mostly transient haematuria, urinary tract infections and stent migration or intolerance). In 14% of the cases salvage UR following initial ET, was performed due to relapse of symptomatic POM. CONCLUSION Endoscopic treatment for persistent or progressive POM in children is a minimally invasive alternative to UR with a long-term modest success rate. Additionally, it can be performed within a wide age span, with equal success rate and complication rates.

Abstract
OBJECTIVE To describe and analyze the clinical manifestation and pre-DRF of UPJO children with polyps and explore the possible influencing factors of supranormal pre-DRF. PATIENTS AND METHODS All patients undergoing primary Anderson-Hynes pyeloplasty for UPJO due to polyp were retrospectively reviewed. Patients' characteristics, parameters of ultrasound and dynamic renograms (DR) were recorded in elaborate. Pre-DRF in groups of different age, weight, gender, pain, grade of hydronephrosis, anterio-posterior pelvic diameter (APD), length of kidney and postoperative ultrasonic parameters were compared. RESULTS A total of 18 UPJO children with polyps were included. Five (27.78%) patients had SFU III grade of hydronephrosis. Seven (38.89%) patients were supranormal pre-DRF. All patients had pre-DRF > 40%. Drainage curve was delayed excretion in 12 (66.67%) patients and T1/2 < 20 min was in 4 (22.22%) patients. Among the 16 patients who underwent preoperative IVP examination, 15 (93.75%) patients had concentration of intrarenal pelvis contrast agent within 10 min. No significant difference in post-APD reduction rate and post-minPT increased was found between supranormal pre-DRF and non-supranormal pre-DRF groups. The supranormal pre-DRF was more likely to occur in young and low-weight children. CONCLUSION The preoperative renal function of UPJO patients with polyps was well preserved, and 38.89% of them had supranormal pre-DRF. Patients with supranormal pre-DRF can be managed with the same strategies as those with normal renal function.

Abstract
Lay summary
Malignant ureteric obstruction (MUO) is frequently encountered in patients with advanced cancers. In the largest study to date, assessing 852 patients from across Scotland, the authors demonstrated the presence of MUO as a marker of advanced disease across cancer types, with poor survival for many patients, even with intervention. There is uncertainty in optimal management of this condition, with marked differences in management between hospitals. Treatment to relieve the obstruction does not guarantee either improvement in kidney function or progression to further oncological treatment. The authors have developed a prognostic tool to estimate outcomes after intervention for MUO, and advocate its use for clinicians along with other data presented for patient counselling.

Abstract
Objective: To compare the efficacy of robotic-assisted single-incision-plus- one-port laparoscopic pyeloplasty (R-SILP+1) with single-incision laparoscopic pyeloplasty (SILP) in pediatric ureteropelvic junction obstruction (UPJO). Methods: The clinical data of 47 children with UPJO who underwent surgery from October 2020 to September 2022 in the Department of Pediatric Surgery of Fujian Provincial Hospital were retrospectively analyzed. According to the surgical method chosen by parents, the children were divided into R-SILP+1 group and SILP group. Baseline data, operative time, intraoperative anastomosis time, volume of blood loss, postoperative hospitalization time, complications, total costs, preoperative and postoperative renal parenchymal thickness (PT), anterior posterior diameter of renal pelvis (APD), and differential renal function (DRF) before and after operation were compared between the two groups, and the clinical efficacy of the two kinds of operation was evaluated. Results: Among the 47 children, 27 were in R-SILP+1 group, including 16 males and 11 females, aged (6.6±3.5) years; 20 were in SILP group, including 12 males and 8 females, aged (6.5±3.5) years. The operations were successful in both groups without conversion to open operation. There were no significant differences between the two groups in baseline data, volume of blood loss, complications, APD and PT at postoperative 6 months, APD, PT and DRF at postoperative 12 months (all P>0.05). Compared with the SILP group, the operative time [(153.0±14.4) vs (189.9±32.6) minutes, P<0.001], intraoperative anastomosis time [(68.8±16.8) vs (97.5±12.0) minutes, P<0.001], postoperative hospitalization time [(6.0±1.3) vs (9.0±1.3) d, P<0.001] were shorter, but the total cost was higher[(57 390±7 664) vs (30 183±4 219) yuan RMB, P<0.001]. Conclusions: Compared with the SILP group, R-SILP+1 can achieve considerable efficacy in treating pediatric UPJO, and has certain advantages in shortening operative time, intraoperative anastomosis time, and postoperative hospitalization time. However, the cost is high.

Abstract
BACKGROUND Cancer of unknown primary (CUP) is a very challenging disease, accounting for 2% to 9% of all new cancer cases. This type of tumor is a heterogeneous tumor whose primary site cannot be determined by standard examination. It has the characteristics of early metastasis, strong aggressiveness, and unpredictable mode of metastasis. Studies have shown that there is no consensus on the treatment of CUP and that there is a wide range of individual differences. In most cases, surgical removal of tumor is the most typical treatment for pelvic tumors. Herein, we report a case of a large pelvic tumor of unknown origin that had compressed the sigmoid colon and ureter and was completely removed by surgery. Postoperative diagnosis was pelvic metastatic squamous cell carcinoma. CASE SUMMARY A 68-year-old man with pelvic tumor who initially complained of recurrent low back pain and painful urination. The mass was initially diagnosed as a pelvic tumor of unknown origin. The patient underwent complete resection of the tumor by laparotomy. The tumor was pathologically diagnosed as squamous cell carcinoma. CONCLUSION Based on the treatment experience of this case, surgery alone cannot improve the poor prognosis of CUP. Since chemotherapy and immunotherapy have achieved promising efficacy in various cancers, and immunotherapy has the characteristics of low side effects and good tolerability, we recommend that patients with CUP should receive chemotherapy and/or immunotherapy for better survival outcomes.

Abstract
INTRODUCTION The management of ureteral strictures longer than 1-2 cm must be treated by major surgery (1, 2). The strictures located at the distal part of the ureter can be managed by a ureteral reimplantation using a psoas hitch or a Boari flap depending on its proximity to the bladder (3). Those located at the proximal ureter can be treated by a pyeloplasty (4). The ureteric strictures in the mid-ureter are the ones that pose a greater challenge for the urologist because a ureteral substitution is needed, either using a segment of the intestine or a buccal mucosa graft (5, 6). Our main objective is to present the management and results at 36 months of a patient with a right mid-ureter stricture. MATERIAL AND METHODS A 63-year-old male with chronic kidney disease (CKD) and a right single functioning kidney was referred to our department with the diagnosis of a 3 cm stricture in the right mid-ureter. He had a long-term JJ-stent in place but in the last year we had to replace it three times precociously and he even needed the placement of a nephrostomy tube due to the obstruction of the JJ-stent. Accordingly, a permanent resolution was sought and a laparoscopic onlay-flap ureteroplasty using cecal appendix was performed. RESULTS The first step was to identify the cecal appendix. Then we identified and dissected the ureter. With the ureter dissected, we performed a ureteroscopy to pinpoint the stricture. Once we knew where the stricture was, we proceeded with the ureterotomy and preparation of the cecal appendix. The final step was to perform the ureteroplasty between the ureter and the cecal appendix placing a JJ-stent before the last stitches were done. Total operative time was 190 minutes without any intraoperative complication. The JJ-stent was removed 7 weeks later. The follow-up of the patient was done with regular blood test and ultrasound to rule out deterioration of the CKD and worsening of the residual hydronephrosis. With a follow-up of 36 months, the patient is stent free, he hasn't had any further intervention and neither the CKD nor the hydronephrosis haven't worsened. CONCLUSIONS Laparoscopic onlay-flap ureteroplasty using cecal appendix is a feasible and well tolerated procedure for patients with right mid-ureter stricture. However, we must bear in mind the difficulty of these cases and they should be performed in expert centers.

Abstract
OBJECTIVE To identify predictive factors for postoperative continence in female Golden Retrievers following cystoscopic-guided laser ablation of intramural ectopic ureters (CLA-EU). ANIMALS 41 client-owned female entire Golden Retrievers with uni- or bilateral intramural ectopic ureter(s) were retrospectively enrolled. METHODS Patients were diagnosed with ectopic ureters with a combination of ultrasonography and cystoscopy. CLA-EU was performed for all dogs so that each ureteral opening was considered to be in an appropriate position by a single operator. All dogs had short-term follow-up 4 weeks and long-term follow up > 10 weeks after the procedure via telephone, which included urinary continence scoring. Clinical factors and ultrasonographic and cystoscopic findings from initial presentation were evaluated to identify predictive factors for postoperative continence. RESULTS Short-term urinary continence was achieved in 46.3% of dogs with no additional medical therapies. Presence of historical urinary tract infections prior to CLA-EU (OR, 0.130; 95% CI, 0.020 to 0.621; P = .018) was negatively correlated and ureteral dilatation (OR, 34.260; 95% CI, 1.813 to 2,143; P = .043) was positively correlated with likelihood of urinary continence. Long-term urinary continence was achieved in 63.4% of dogs, and presence of historical urinary tract infections was negatively prognostic (OR, 0.173; 95% CI, 0.023 to 0.856; P = .048). CLINICAL RELEVANCE Female Golden Retrievers undergoing CLA-EU have similar outcomes to those reported for other mixed-breed cohorts with > 30% of dogs failing to regain urinary continence. Historical urinary tract infections were significantly associated with both short- and long-term urinary continence in our population.

Abstract
OBJECTIVE To evaluate objective treatment efficacy and safety, and subjective patient-reported outcomes in patients with complex ureteral strictures (US) undergoing minimally invasive lingual mucosal graft ureteroplasty (LMGU). MATERIALS AND METHODS We prospectively enrolled patients underwent robotic or laparoscopic LMGU between May 2020 and July 2022. Clinical success was defined as symptom-free and no radiographic evidence of re-obstruction. Patient-reported outcomes, including health-related quality of life (HRQoL), mental health status and oral health-related quality of life (OHRQoL), were longitudinally evaluated before surgery, 6 and 12 months postoperatively. RESULTS Overall, 41 consecutive patients were included. All procedures were performed successfully with 32 patients in robotic approach and 9 in laparoscopic. Forty (97.56%) patients achieved clinical success during the median follow-up of 29 (range 15-41) months. Although patients with complex US experienced poor baseline HRQoL, there was a remarkable improvement following LMGU. Specifically, the 6-month and 12-month postoperative scores were significantly improved compared to the baseline (p < 0.05) in most domains. Twenty-eight (68.3%) and 31 (75.6%) patients had anxiety and depression symptoms before surgery, respectively. However, no significant decrease in the incidence of these symptoms was observed postoperatively. Moreover, there was no significant deterioration of OHRQoL at 6 months and 12 months postoperatively when compared to the baseline. CONCLUSIONS LMGU is a safe and efficient procedure for complex ureteral reconstruction that significantly improves patient-reported HRQoL without compromising OHRQoL. Assessing patients' quality of life enables us to monitor postoperative recovery and progress, which should be considered as one of the criteria for surgical success.

Abstract
Ureteral strictures can occur along the entire course of the ureter and have many different causes. Factors involved in the development include, among other things, congenital anomalies, iatrogenic injuries during endoscopic as well as open or minimally invasive visceral surgical, gynecological, and urological procedures as well as prior radiation therapy. Planning treatment for ureteral strictures requires a detailed assessment of stricture and patient characteristics. Given the various options for ureteral reconstruction, various methods must be considered for each patient. Short-segment proximal strictures and strictures at the pyeloureteral junction are typically surgically managed with Anderson-Hynes pyeloplasty. End-to-end anastomosis can be performed for short-segment proximal and middle ureteral strictures. Distal strictures are treated with ureteroneocystostomy and are often combined with a Boari and/or Psoas Hitch flap. Particularly, the treatment of long-segment strictures in the proximal and middle ureter remain a surgical challenge. The use of bowel interposition is an established treatment option for this, offering good functional results but also potential associated complications. Robot-assisted surgery is increasingly becoming a minimally invasive treatment alternative to reduce hospital stays and optimize postoperative recovery. However, open surgical ureteral reconstruction remains an established procedure, especially after multiple previous abdominal operations.

Abstract
OBJECTIVE To characterize the outcomes of ileal interposition for the management of ureteral obstruction from tumor and ureteral stricture following treatment for abdominopelvic malignancy. MATERIALS AND METHODS A retrospective database analysis was performed for all cases of ileal interposition performed by 5 surgeons from January 2013 to December 2020. Patients were ≥18 years of age and included if undergoing ileal interposition in either the primary setting of a surgical procedure for tumor extirpation or in the delayed setting. RESULTS In total, 23 patients who underwent repair of 27 ureteral units were included. The mean age was 60.2 years. Median follow-up was 21.6 months. The most common primary diagnoses were urothelial (35%), colorectal (31%), and cervical (22%) cancer. The etiologies of ureteral obstruction were malignant in 48% and ureteral stricture in 52%. Types of repairs included unilateral interposition in 13 patients, bilateral interposition in 1 patient, interposition to an ileal conduit in 3 patients, and interposition with cystoplasty in 6 patients. There was a statistically significant difference between the mean preoperative (Creatinine 1.05 mg/dL, Estimated Glomerular Filtration Rate 77 ml/min/1.73 m2) renal function and postoperative (Creatinine 1.26 mg/dL, Estimated Glomerular Filtration Rate 67 mL/min/1.73 m2) renal function at the most recent follow-up (P = .024). Eight minor (grade 1-2) and 6 major (grade ≥3) complications developed for a minor and major complication rate of 35% and 26%, respectively. CONCLUSION Ileal interposition is successfully utilized as a reconstructive technique at the time of enbloc resection involving the ureter and to address ureteral stricture in the delayed setting.

Abstract
PURPOSE To identify the risk factors for adverse outcomes after pediatric pyeloplasty. METHODS We conducted a retrospective review of all children under the age of 14 years who underwent primary pyeloplasty for unilateral ureteropelvic junction (UPJ) obstruction at a single teaching hospital in Tunisia between January 1, 2013, and December 31, 2022. RESULTS A total of 103 patients were included. Median age of patients at surgery was 27 months (interquartile range [IQR], 13-44). On ultrasound, median renal pelvic anteroposterior diameter was 3.2 cm (IQR, 2.3-4), and the median renal cortex thickness (RCT) was 2.5 mm (IQR, 2-3.5). Median differential renal function (DRF) on preoperative radionuclide renal scan was 40% (IQR, 30-46). Postoperative adverse outcomes occurred in 28 patients (27.2%). These included 19 cases of urinary tract infections (UTIs), 11 cases of UPJ restenosis, four cases of UPJ leakage, two cases of urinoma, and two cases of diversion-related complications. Multivariate logistic regression analysis revealed two factors significantly and independently related to postoperative negative outcomes: RCT <3 mm and DRF > 50%. CONCLUSION Our study demonstrated that preoperative RCT on ultrasound of less than 3 mm and preoperative DRF on radionuclide renal scan of more than 50% were independent risk factors for adverse outcomes following pediatric pyeloplasty. These factors could be of interest in identifying, early on, patients who will develop postoperative negative outcomes, giving them more attention and support, and explaining the prognosis to the patient and family.
