Robotic-assisted laparoscopic ureteropyelostomy for treatment of prostatitis secondary to ectopic ureteral insertion of a completely duplicated collecting system.

Symptomatic presentation of a completely duplicated collecting system with upper-pole ectopic ureteral insertion is rare in the adult. We present a case of a 52-year-old man with recurrent prostatitis and hematuria secondary to an ectopic ureteral insertion from a left upper-pole moiety in a completely duplicated collecting system. He underwent a robot-assisted laparoscopic ureteropyelostomy with good results. We describe our technique in this unusual case.
