Rare Entity of Proximal Ureteral Diverticulum Managed by Robotic Resection and Ureteroureteral Anastomosis.

Ureteral diverticulum (UD) is a rare condition. It can be congenital, acquired, or an abortive ureteral duplication. Majority can be managed conservatively. The symptomatic and complicated diverticulum entails an intervention. There have been reports of UD treated with open reconstructive surgery, nephrectomy, and laparoscopic surgeries. We present here a case of UD that presented with loin pain and decreased renal function and underwent robot-assisted laparoscopic diverticulectomy and ureteroureteral anastomosis. UD is a rare condition with only 47 cases reported in the literature. Management depends on symptoms and complications. Our case is the first in the literature to be managed robotically.
