Although iatrogenic ureteral injuries are rare, they have potentially devastating consequences for both patients and physicians, and their management remains challenging. We report a case of a 51-year-old morbidly obese (body mass index = 63) woman who suffered an iatrogenic 15-cm right ureteral avulsion during hysteroscopic biopsy. Preoperative antegrade and retrograde pyelograms demonstrated no true renal pelvis and a 3-cm blind-ending distal ureteral stump. The patient underwent a right robotic downward nephropexy, psoas hitch, lower pole calycostomy, and 11-cm appendiceal interposition. At 6 months postoperatively, renal scan demonstrated stable right renal function with no evidence of obstruction.
