Ureterosciatic Hernia Treated with Laparoscopic Intraperitonization of the Ureter

Ureterosciatic hernia (USH) is a rare benign disease. We report a case of USH treated with laparoscopic intraperitonization of the ureter. A 70-year-old woman was admitted to our hospital with right abdominal pain lasting for 2 months. CT showed right hydronephrosis and invagination of the right ureter into the right sciatic foramen. She underwent retrograde ureterography, which revealed abnormal tortuosity of the right lower ureter, and was found to have USH. We performed laparoscopic intraperitonization of the ureter and she presented good postoperative course. Laparoscopic intraperitonization of the ureter can be a useful treatment for USH.
