Ureteral duplication is rarely seen malformation that could be diagnosed during radiological imaging. Herein, we present 5 patients with ureteral duplication who underwent robotic radical cystectomy with intracorporeal urinary diversion for bladder cancer. Preoperative computerized tomography did not show presence of a ureteral duplication in any patient and all were identified intraoperatively. A Wallace type uretero-ureteral anastomosis was performed in all patients. During the follow-up period, we did not detect any ureterointestinal anastomotic strictures or complication related to the presence of a ureteral duplication following robotic cystectomy. We conclude that ureteral duplication might be missed during preoperative radiological imaging, might be a surprising and challenging issue for the robotic surgeon that could be safely managed intraoperatively.
