A complete duplicated collecting system with giant ureterocele in adult: Case report

Introduction: Ureteroceles is a developmental anomaly with cystic dilation of the distal aspect of the ureter and are often associated with some urological anomaly such as a duplicated system or stenotic ureteric orifice. Presentation of case: This study reports an ectopic ureterocele in duplication of collecting system associated with double ureters and ureteral ectopia in a woman aged 24 years with minor flank pain. Cystoscopy deroofing of the ureterocele performed and followed by secondary surgery laparoscopic heminephrectomy. Discussion: Ureteroceles have various clinical manifestations and complications. Treatment for ureterocele depends on age, type of the ureterocele, obstruction to the draining system, and complications. No single method is sufficient for all cases, and management must be individualized. Endoscopic treatment has gradually broadened as a safe, minimally invasive, and effective procedure, but there is no consensus on its effectiveness for treating ectopic ureterocele. However, it is reported that 50–80 of cases after initial endoscopic treatment require secondary surgery. Conclusions: Ureterocele is reported rarely in adults, especially with duplication of the collection system in the nonorthotopic (extravesical) position in women. Cystoscopy deroofing of the ureterocele can be performed to decompress the hydroureteronephrosis, and laparoscopic heminephrectomy can be performed due to dysfunctional uppers moiety. Long-term follow-up is required to monitor renal function, symptoms, and occurrence of vesicoureteric reflux. © 2021 The Authors
