Ipsilateral Ureteroureterostomy in the Surgical Management of the Severely Dilated Ureter in Ureteral Duplication

Purpose: Ipsilateral ureteroureterostomy for the surgical management of severely dilated ureter in ureteral duplication is well supported in the surgical literature but often not done. We evaluated our institutional experience with ureteroureterostomy in duplication anomalies to assess the feasibility and success of this procedure.Materials and Methods: An 8-year retrospective review of the records of all patients with complete renal duplex anomalies was evaluated. Anatomical presentations, and operative and nonoperative treatment of these patients were evaluated.Results: A total of 193 patients were identified with complete renal duplication. Associated anomalies included ureterocele in 24 patients, ectopic ureter in 38 and vesicoureteral reflux in 57. Of 193 patients 160 (83%) with duplex anomalies underwent surgical intervention with a total of 41 ureteroureterostomies performed in 39 patients with dilated donor ureters. A total of 11 ureteroureterostomies were performed primarily and 30 were performed...
