Lower-Pole Ureterocele With Upper-Pole Ureteropelvic Junction Obstruction in a Complete Duplex Collecting System: A Case Report

Year: 2026

Type: article

Abstract: The duplication of the collecting system is a rare congenital anomaly that is detected prenatally or at birth through ultrasound.We report a six-month-old female patient demonstrating a lower-pole ureterocele with upper-pole ureteropelvic junction obstruction in a complete left duplex collecting system.A voiding cystourethrogram and magnetic resonance urogram showed complete duplication of the collecting system with respective upper and lower moieties of the left kidney.Subsequently, intraoperative cystoscopy and fluoroscopy confirmed the anatomical relation of the ureterocele and its connection to the lower renal moiety.The ureterocele was resected and a pyeloplasty was performed to correct the upper moiety ureteropelvic junction obstruction.Cystoscopy and retrograde pyelography may be necessary to definitively assign duplicated ureters to their corresponding renal moieties when cross-sectional imaging is inconclusive.
