Robot-assisted transperitoneal reconstruction of a retrocaval ureter: A report of two cases.

A retrocaval ureter (RCU) is a rare cause of congenital ureteral obstruction that often requires surgical repair. We report two cases of RCU in adults treated with robot-assisted laparoscopic surgery. In both cases, we performed robotic ureteroureterostomy with dissection of the entire length of the retrocaval portion of the right ureter without complications. In the second case, renal stone removal was simultaneously performed. The robot-assisted procedure we performed could be considered safe and feasible for the surgical repair of an RCU.
