Ureteral injuries in an obstetrics and gynecology training program: etiology and management

Abstract

Between July 1980 and September 1987, 3185 major gynecologic operations were performed in our residency program. Ureteral injury occurred in 17 cases, 14 of which (0.4%) were accidental. In 16 cases, the injury was noted intraoperatively and repaired primarily; one injury was repaired after identification on the fourth postoperative day. Large pelvic masses, which limited exposure, and tumor invasion of the parametrium contributed to ureteral injury. Preoperative intravenous pyelogram or computed tomography did not prevent ureteral damage. Sixteen ureteroneocystostomies were performed with good result. One ureteroureterostomy leaked, but healed over a percutaneous stent without problems. All patients subsequently had normal renal function.
