Background: Hydronephrosis in children is a common congenital urologic problem with pelviureteric junction obstruction being its most common cause. This study was conducted to evaluate the outcome of pyeloplasty for congenital pelviureteric junction obstruction in children.
Methods: This study was conducted in department of Paediatric Surgery, Quaid-e-Azam Medical College/Bahawal Victoria Hospital, Bahawalpur from July 2008 to December 2010. A total of 50 patients diagnosed on ultrasonography and intravenous urogram as having PUJ obstruction were included. Patients with history of previous repair were excluded. Both Dismembered (Anderson Hynes) and Non-dismembered (Flap procedures) pyeloplasties were performed depending upon the size of pelvis and degree of dilatation. Initial follow-up was after 1 week, then after 15 days and then monthly for 3 months. Minimum follow-up period was 6 months and maximum 15 months. At three month, excretory urography was obtained to assess the function of that particular renal unit.
Results: Lumbar pain and flank mass were the commonest presenting complaints. Thirty-six (72%) patients were male. Left sided obstruction was in 32 (64%) cases, right-sided in 15 (30%), and 3 (6%) cases were bilateral. Common post-operative complications were urinoma formation and re-stenosis in two cases each. There was also no gross difference of outcome in pyeloplasty whether done with or without double-J (DJ) stents. Moreover, dismembered pyeloplasty resulted in better outcome.
Conclusions: Open pyeloplasty is the "Gold Standard" treatment option for congenital pelviureteric junction obstruction. The use of DJ Stents is not necessary in every repair.

Congenital obstruction of the upper urinary tract is often caused by the pyeloureteral junction syndrome, the lower polar vessel being the most common extrinsic etiology. We report on a case that was successfully treated using the Vascular HITCH, an alternative method with lower morbidity than Anderson and Hynes pyeloplasty considered the gold standard procedure. Our objective is to outline the aforementioned method and illustrate its ease of use and possible efficacy in carefully chosen adult patients.

Introduction: To evaluate the feasibility, safety, and effectiveness of different pyeloplasty procedure approaches for pelvicureteric junction (PUJ) obstruction in kidney anomalies. The presence of difficult, unfamiliar and anomalous anatomy makes pyeloplasty challenging in these conditions.
Patients And Methods: We conducted a retrospective review of pyeloplasty in patients with congenital anomalous kidneys at our national tertiary referral centre.

Background: The aim of this study was to report our technique and medium-term outcomes of modified robot-assisted laparoscopic dismembered pyeloplasty (RALDP) in the Lithotomy Trendelenburg position for treating adult ureteropelvic junction obstruction (UPJO) with horseshoe kidney (HSK).
Methods: Between March 2021 and March 2023, 11 adult patients with UPJO and HSK underwent modified RALDP in the lithotomy Trendelenburg position. Patient demographic characteristics, perioperative parameters, and follow-up outcomes were collected prospectively and analyzed.
