[Iatrogenic injuries to the distal ureter during gynecologic interventions].

Surgical injury to the ureter is an important problem that confronts the urologist, the gynecologist and the general surgeon. The authors report 20 cases of iatrogenic pelvic ureteral injuries (22 ureters) observed after gynecological surgery between January 1985 and January 1995. The ureter was injured during ligation of the lumbo-ovarian vascular pedicle because it was inadequately protected during the operation. Open surgery and double pigtail stent insertion using retrograde route were used for treatment. The iatrogenic ureteral injury was in 18 patients unilateral and in the remaining 2 patients both ureters were damaged. As regards treatment, the authors recommend immediate repair, whenever the lesion is noticed at operation. In the post-operative period, ureteral stent or double pigtail stent insertion using balloon dilatation or ureteroscope, may be a successful conservative treatment. If the damage is only diagnosed subsequently, they recommend a ureterovesical implantation, using the psoas hitch bladder procedure or the Boari-Cassati-Küss procedure if the lesion is in the lower ureter or a transuretero-ureterostomy if it is in the upper ureter.
