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.

<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.

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.

Objectives We aimed to investigate the safety concerns associated with placing double-J ureteric stents post-laparoscopic pyeloplasty surgery for congenital ureteropelvic junction obstruction (UPJO) and hydronephrosis. Methods A total of 1349 patients with postoperative double-J stent placement at our center were included. Clinical variables for enrolled patients were collected by two independent authors. We compared clinical variables and the efficacy of stenting post-laparoscopic pyeloplasty. Results The mean age of the patients was 4.23 ± 2.39 years. A total of 58.49% of patients were diagnosed with left UPJO with hydronephrosis and 33.95% were diagnosed with right UPJO. Furthermore, 7.56% of patients had bilateral UPJO. In all cases, 96.96% of indwelling double-J stents were successfully removed 4 weeks post-surgery. A total of 3.04% of the patients still required further management, including stent migration to the renal pelvis (0.37%), stent migration to the bladder (0.30%), prolapse of the stent through the ureter (0.15%), blockage of stents (1.85%), and fouling of stents (0.37%). Conclusions Double-J ureteric stents used after laparoscopic pyeloplasty for treating UPJO in hydronephrosis for pediatric patients is a safe, feasible, and beneficial method, which can be recommended for routine procedures. However, caution should be practiced for follow-up and removal using this method.

General Data

Objective: To summarize our experiences with drainage methods after laparoscopic pyeloplasty with a 14-year study.Methods: We reviewed the data of the 838 children operated on for hydronephrosis due to congenital ureteropelvic junction obstruction (UPJO) between July 2007 and July 2020. Patients' demographics, perioperative details, postoperative drainage stents [including double-J stent, percutaneous trans-anastomotic (PU) stent, and trans-uretero-cystic external urethral stent (TEUS)], complications, hospital stay, and long-term follow-up outcomes were analyzed. Long-term follow-up was performed by outpatient visits and telephone follow-up. Moreover, we reviewed the details of nine cases of recurrence after laparoscopic pyeloplasty.Results: Comparison of preoperative general data among the three groups indicated that there was no statistical difference in age, gender, and surgical side of the three groups. Statistical differences were found in the incidence of postoperative complications from the three postoperative drainage method groups, especially the incidence of reoperations (p &lt; 0.01): there were six cases (3.19%) of recurrences in the TEUS group, two cases (0.36%) in the DJ group, and one case (0.93%) in the PU group. In the six recurrent cases from the TEUS group, four cases (44.4%) were found to have stenosis, and two cases (22.2%) have iatrogenic valvular formation.Conclusion: Not all three types of drainage methods are suitable for drainage after pyeloplasty. Based on our findings, TEUS is not recommended.

INTRODUCTION Over the last 20 years, the surgical management of ureteropelvic junction obstruction (UPJO) has been revolutionised by the development of endourological instrumentation and several minimally invasive procedures including: antegrade or retrograde endopyelotomy, retrograde balloon dilatation, and laparoscopic pyeloplasty. Currently, in our department, we offer percutaneous antegrade endopyelotomy (PAE) as primary treatment of UPJO in adults, believing it offers less morbidity, better cosmetic results, and quicker operating time compared with open pyeloplasty. PATIENTS AND METHODS We performed a retrospective audit of our results for the 14 patients who underwent percutaneous antegrade endopyelotomy between January 2000 and May 2004. RESULTS Mean operative time was 53 min (range, 30–80 min), mean in-patient stay was 3.8 days (range, 2–7 days), and there were no major postoperative complications for this series with mean follow-up of 31.8 months (range, 12–52 months). Eleven out of the 14 patients (79%) showed radiological improvement on their 3-month MAG 3 (mercaptoacetyl-triglycyl) renogram, and 13 out of the 14 (93%) patients reported significant reduction or resolution of pain, compared with their preoperative state. CONCLUSIONS The majority of urologists still offer open pyeloplasty as primary treatment for UPJO with laparoscopic pyeloplasty currently an evolving procedure in the UK. Our series reports comparable success rates for PAE compared to other series. Despite these results, we feel that the future role of percutaneous endopyelotomy will be as a salvage procedure following failed open or laparoscopic surgery. However, in patients with concurrent stone disease or requiring antegrade ureteric access, percutaneous endopyelotomy would be suitable as a primary treatment option.

Background: Historically open pyeloplasty has been regarded as the gold standard for the surgical management of ureteropelvic junction obstruction (UPJO). The treatment of this condition has evolved considerably over the past two decades resulting in new surgical approaches. One of these approaches is laparoscopic pyeloplasty,this technique aimed to achieve the same results as open surgery,with lower rates of morbidity and complications.  Aim of the study: To compare the operative time,hospital stay,analgesic use,perioperative complications,and success rate between laparoscopic and open pyeloplasty in Al Diwaniya Teaching Hospital. Patients & Methods: From October 2014 to October 2016,40 patients (26 males and 14 females) with Ureteropelvic junction obstruction who had been admitted to the urology unit of Al Diwaniya Teaching Hospital were enrolled in this study. Their ages ranged from 10 to 44 years with a mean age of 24 years. The patients were selected on the basis of standard indications for PUJO repair. The patients were assigned into two groups. Twenty patients underwent transperitoneal laparoscopic pyeloplasty and 20 patients underwent open surgery. The choice between the two types of operation was selected according to surgeon's preference (only surgeon who has enough experience with laparoscopic surgeries perform laparoscopic pyeloplasty,while the other performed open surgery). Preoperative evaluations were done using abdominal ultrasound and IVP. Laboratory tests included urinalysis,urine culture,blood urea,and serum creatinine. Blood group was determined. We compared the operative time,complications rates,hospital stay and success rate of the two groups.Mean operative time was 2 hours and 3 hours in open and laparoscopic pyeloplasty groups,respectively. Mean hospital stay was shorter (24 hours) in the laparoscopic group and (48 hours) in open group. Mean follow-up period was 9 months. Postoperative complication rates were 20 % and 30 % in laparoscopic and open pyeloplasty groups,respectively. Success rates were 95% and 90 % for open and laparoscopic pyeloplasty groups,respectively. Repeated surgery was performed in 2 patients of laparoscopy and 1 of open pyeloplasty groups due to recurrence of stricture.The safety and efficacy of laparoscopic pyeloplasty is comparable to that of open pyeloplasty,with better cosmetic results and shorter hospital stay,therefore laparoscopic pyeloplasty can replace open surgery and may be considered the gold standard technique for the treatment of ureteropelvic junction obstruction in expert hands.
