Introduction: We report our experience with laparoscopic management of ureteropelvic junction obstruction in horseshoe kidneys.Methods: Between February 2004 and March 2014, 15 patients with horseshoe kidneys and symptomatic ureteropelvic junction obstruction underwent laparoscopic management at our national referral centre. Depending on the anatomy and presence of obtrusive vessels or isthmus, we performed either dismembered, Scardino or Foley YV pyeloplasty, or Hellstrom vessel transposition. Patients were initially evaluated by ultrasonography, then diuretic scintiscan at 4 to 6 months, and followed by yearly clinical and sonographic exams.Results: This study included 11 male and 4 female patients between the ages of 4 to 51 year (average 17.7). The left kidney was involved in 12 patients (80%). Operation time was 129 minutes (range: 90–186), and patients were discharged within 2.8 days (range: 1–6). Although 8 (53.3%) patients had crossing vessels, of which 6 required transposing, the Hellstrom technique was solely used in 3 cases, of which notably 1 case failed to resolve and required laparoscopic Hynes within the next year. Eight cases underwent dismembered pyeloplasty, 2 Foley YV, 1 Scardino flap and 1 required isthmectomy and vessel suspension. At the mean follow-up of 60 (range: 18–120) months, the overall success rate was 93.3%.Conclusions: To our knowledge, this represents the largest report on laparoscopic pyeloplasty for horseshoe kidneys, providing the longest follow-up. Our findings confirm prior reports supporting laparoscopy and furthermore show that despite the prevalence of crossing vessels, transposition alone is seldom sufficient.

Introduction Surgery for ureteropelvic junction obstruction (UPJO) is performed by both pediatric surgeons (PS) and urologists (URO). The aim of this study was to analyze treatment modalities for UPJO and results in relation to the surgical technique and the operating discipline in Germany. Materials and Methods Data of patients aged 0 to 18 years were extracted from a major public health insurance (covering ∼5.7 million clients) during 2009 to 2016 and were analyzed for sociodemographic variables, surgical technique, and treating discipline. Logistic regression analysis was performed for the risk of a complication within the first postoperative year. Results A total of 229 children (31.0% female) were included. Laparoscopic pyeloplasty (LP) was performed in 58 (25.3%) patients (8.6 ± 6.4 years), and open pyeloplasty (OP) was applied in 171 (74.7%; 4.6 ± 5.9 years). LP was the dominant technique in females (p < 0.02); males preferentially underwent OP (p < 0.02). Length of hospital stay was 4.3 days (p = 0.0005) shorter in LP compared with that in OP, especially in children ≤ 2 years (6.7 days, p = 0.007). PS operated on 162 children (70.7%), and URO performed surgery on 67 patients (29.3%). The mean age of children operated by PS (3.5 ± 4.7 years) was significantly younger compared with that operated by URO (10.8 ± 6.5 years, p < 0.0001). Complication rates were independent of surgical technique or treating specialty. Conclusion In Germany, UPJO was treated by LP in 25.3% of patients, which was associated with a shorter length of stay, especially in children ≤ 2 years. Complication rates were independent of the operating specialty and surgical technique. Therefore, LP should be further promoted for the treatment of UPJO in small children.

Objective: The aim of the objective was to present our initial experience and evaluate the feasibility of the novel comprehensive modified laparoscopic pyeloplasty (CMLP) technique based on membrane anatomy. Materials and Methods: Forty-eight patients underwent CMLP from February 2016 to October 2020. CMLP involves the following: dissection of the ureter was based on the fascia or fusion fascia formed by embryonic development. The ureter was separated from the ureteral sheath, and the pelvis and ureter were incised with incomplete amputation. The first stitch was placed between the lower point of the spatulated ureter and the lowest corner of the renal pelvis to ensure correct orientation of the anastomosis; anastomosis of the renal pelvis and ureter was performed using the touchless technique. Results: All CMLPs were completed successfully without conversion. The mean overall operating time was 230.96 min. The median estimated blood loss was 50.00 (interquartile range 20.00–57.50) mL. The average postoperative hospital stay was 9.31 days. The average follow-up time was 24.73 months. No major complications occurred. In 1 case, revision laparoscopic pyeloplasty was performed, but the obstruction persisted after double J stent removal, so ultimately, the double J stent required regular replacement. Another asymptomatic patient with hydronephrosis experienced failed treatment and is still under follow-up. The overall success rate was 95.83% (46/48). The success rate in patients with recurrent ureteropelvic junction obstruction (UPJO) was 87.5% (7/8). Conclusions: CMLP is a practical and effective treatment option for UPJO with a high success rate. An advantage of CMLP is the clear surgical field.

Objective: The open Anderson–Hynes procedure has an overall success rate of 90% for ureteropelvic junction obstruction. Laparoscopic pyeloplasty (LP) was developed to reduce morbidity and hospital stay while preserving the excellent results. We report on the results of our experience with laparoscopic pyeloplasty.Methods: Between January 2001 and May 2006, 77 consecutive patients underwent LP performed by one of 4 surgeons at our institution. Patients were reassessed with ultrasound (U/S) or intravenous pyelogram (IVP) at 6 weeks. Diuretic renal scan and U/S or IVP were performed at 6 months, and subsequent follow-up included a U/S or IVP as well as clinical assessment. Patients were assessed for pain and hydronephrosis on radiologic imaging, clearance on diuretic renal scan (T1/2) and differential renal function.Results: We evaluated 73 patients. The mean patient age was 38 years (range 16–71 yr), the mean operating time was 218 minutes (range 110–409 min), and the mean blood loss was 57 mL (range 25–250 mL). Mean hospital stay was 3.0 days (range 2–7 d). The success rate was 90.4%, and failures were mainly due to poor function after surgery (3 patients). Pyelolithotomy was performed concomitantly on 6 patients, which on average extended operative time by 36 minutes.Conclusion: Our success rates are consistent with the LP experience of other centres and are comparable with rates for the open technique. Patients had short hospital stays, and complications were negligible. With experienced surgeons, LP should be the first-line treatment for ureteropelvic junction obstruction.

Objective: To evaluate prospectively the results obtained in 16 patients undergoing laparoscopic pyeloplasty through transperitoneal access. Materials and Methods: The study was conducted in the department of urology, BSMMU, Dhaka between the periods of March 2013 and June 2014, sixteen patients between 15 and 48 years old, were treated for ureteropelvic junction obstruction (UPJO) via a transperitoneal laparoscopy. All patients had clinical symptoms of urinary obstruction and hydronephrosis were confirmed by imaging methods. Anderson-Hynes dismembered pyeloplasty was performed in all patients. Patients were clinically and imaging evaluated in the postoperative period at 6 and 12 weeks. Results: Most of the patients were male (68.75%) and female were 31.25%. The mean operative time was 127.37 (±15.67) minutes ranged from 95 to 240 minutes. Pain score in first postoperative day and third postoperative day following pyeloplasty were 20.87 (±6.83) and 4.75 (±3.34) respectively. The mean hospital stay was 4.25 (±1.34) days. Anomalous vessels were identified in 4 patients, intrinsic stenosis in 12 patients. Postoperative urine leakage and UTI were seen 18.75%, 12.50% subject respectively. Split renal function and GFR were significantly improved (p<0.05) and improvement of renal functional outcome was 87.50%. Conclusion: Laparoscopic pyeloplasty had the advantages like less postoperative pain and shorter hospital stay. Bangladesh Journal of Urology, Vol. 19, No. 2, July 2016 p.59-63

Purpose: The aim of this study was to evaluate the outcomes of laparoscopic pyeloplasty in children less than 12 months of age. Materials and methods: The records of 20 infants, who had pelviureteric junction obstruction and subsequently underwent LP from January 2013 to November 2016 with at least 1 year of follow-up, were retrospectively reviewed. Patients demographics, the results of preoperative and postoperative imaging studies, perioperative details, complications, and results were noted. Results: The mean age of 20 infants was 4.75 months. The gender of cases was 5 females (25%) and 15 males (75%). Of that, 13 (65%) laparoscopic pyeloplasties were in left side and 7 (35%) were in right side. No cases needed open conversation. Aberrant crossing vessel was observed in three patients (15%). The mean operation time was 79.35 min (45–128 min). The mean hospital stay was 2.9 ± 0.308 days (2–3 days). There were complications in three children (15%); two patients developed stent migration and one child had fever over 38°. Three children with complications did not require a second intervention. In one child, the kidney was non-functioning in follow-up and nephrectomy was performed. The anteroposterior diameter significantly reduced. Preoperative mean value was 24.305 ± 5.6157 and postoperative mean value was 15.40 ± 6.030 (p = 0.000, p < 0.05). There was a significant degree of improvement in renal split function for all patients. Preoperative mean values were 45.53 ± 11.512, while postoperative values were 47.850 ± 13.347 (p = 0.029, p < 0.05). Conclusion: Although there are doubts about the reliability and efficacy of results for pyeloplasty in children less 12 months, many studies including this study show that laparoscopic pyeloplasty is an effective and reliable method for infants.

<b><i>Objectives:</i></b> The aim of the study was to present our modified flap pyeloplasty techniques for recurrent ureteropelvic junction obstruction (UPJO) with a long proximal ureteral stricture and compare outcomes of laparoscopic and robotic procedures. <b><i>Materials and Methods:</i></b> Between March 2018 and January 2020, 21 patients underwent modified laparoscopic or robotic flap pyeloplasty for recurrent UPJO with a long proximal ureteral stricture. Our surgical modifications included the “wishbone” anastomosis and “ureteral plate” technique. Demographic, perioperative, and follow-up data were recorded and compared retrospectively between the groups. Success was defined as subjective pain alleviation and hydronephrosis improvement. <b><i>Results:</i></b> Thirteen modified laparoscopic flap pyeloplasty (mLFP) and 8 modified robotic flap pyeloplasty (mRFP) were performed successfully without conversion. mRFP tended to have shorter overall operative time (142.4 vs. 179.1 min, <i>p</i> = 0.122) and anastomosis time (43.1 vs. 61.0 min, <i>p</i> = 0.093) than mLFP. No difference was found in estimated blood loss (<i>p</i> = 0.723) and pararenal draining time (<i>p</i> = 0.175) between the groups. The mean postoperative hospital stay of mRFP was significantly shorter than that of mLFP (5.0 vs. 8.2 days, <i>p</i> = 0.015). No major complications occurred. During the mean follow-up of 17.9 months, the overall success rate was 90.5%, and there was no significant difference between 2 groups. <b><i>Conclusions:</i></b> The modified flap pyeloplasty could be considered a practical and effective treatment option with a high success rate for recurrent UPJO with a long proximal ureteral stricture, and the robotic procedures showed advantages of higher efficiency and faster recovery.
