Aim: The aim of the study was to compare the efficacy and postoperative complications of stented and nonstented open pediatric dismembered pyeloplasty for ureteropelvic junction (UPJ) obstruction.
Settings And Design: A balanced, parallel group, prospective randomized controlled trial comparing stented and nonstented Anderson-Hynes Dismembered Pyeloplasty.
Subjects And Methods: It included 42 children who required Anderson-Hynes dismembered pyeloplasty for UPJ obstruction (UPJO). Patients were randomized into stented (double "J" [DJ] stent) and nonstented pyeloplasty groups. The intraoperative and postoperative course was compared. Both groups were analyzed for problems such as dysuria, frequency, pain, hematuria and urinary tract infection, and postoperative renal status.
Statistical Analysis: Mann-Whitney U-test, Fisher's exact test, Student's -tests, and Chi-squared test were used.
Results: Surgical duration was significantly shorter for the nonstented group as compared to the stented group (60.4 ± 6.49 min vs. 78.9 ± 8.17 min). The intraoperative negotiation of DJ stent was troublesome in 21.7% patients belonging to the stented group. The hospital stay was comparable in both groups (4.67 ± 1.9 vs. 4.28 ± 0.67 days). Patients in stented group had experienced dysuria, loin pain, lower abdominal spasmodic pain, and frequency significantly higher than nonstented group. However, the other problems such as fever, hematuria, and urinary tract infections were more common in stented group, but the difference was not statistically significant. There was no difference in resolution of hydronephrosis in both groups.
Conclusions: There is no statistically significant difference in resolution of hydronephrosis following nonstented or stented dismembered pyeloplasty in children with UPJO. However, the patient is more symptomatic due to stent in the postoperative period.

Background: The study aimed at evaluating the role of thiol-disulphide balance parameters [native thiol (SH), total thiol (SH + SS), disulphide (SS), disulphide/native thiol ratio (% SS/SH), disulphide/total thiol ratio (% SS/Total Thiol) and native thiol/total thiol ratio (%SH/Total Thiol)], which are important oxidative stress markers in the congenital ureteropelvic junction (UPJ) stenosis, in the diagnosis of the disease, and its role in determining the need for surgery and follow-up.
Materials And Methods: This prospective study included 30 children diagnosed with congenital intrinsic ureteropelvic junction obstruction (UPJO) and a control group of 30 healthy children admitted to the pediatric clinic between January 2016 and February 2017. The children with UPJO underwent laparoscopic dismembered pyeloplasty.

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.

Objective: To present a unique set of patients diagnosed with megacalycosis by magnetic resonance urography (MRU) to re-evaluate the definition of megacalycosis and provide a new perspective on diagnosis and treatment.
Materials And Methods: A retrospective chart review of patients with megacalycosis as diagnosed by MRU was conducted. MRU was performed to determine the presence of obstruction, further visualize renal anatomy, and clarify the presence of megacalycosis.

Introduction: Dismembered laparoscopic pyeloplasty (LP) is a well-accepted treatment modality for ureteropelvic junction obstruction (UPJO) in children. However, its efficacy and safety in infants, particularly neonates, remain uncertain. To address this significant knowledge gap, we aimed to compare outcomes between a cohort of neonates and infants undergoing LP vs.
