Urological trauma after gynecological and obstetric surgeries - An 18-year single-center experience

Objective. Gynecological and obstetric surgeries are not uncommon causes of iatrogenic injury of the urinary tract. Herein, we retrospectively report our experience with these injuries over the last 18 years. Material and methods. Between 1985 and 2003, 120 females (mean age 34.2 +/- 13.7 years) were included in this study. The types of injury were as follows: vesicovaginal fistula, n=90; ureterovaginal fistula, n=14, ureteric ligation, n=13, vesicouterine fistula, n=2; and ureterouterine fistula, n=1. Definitive repair of such injuries was performed in all cases, including 10 cases of recurrent vesicovaginal fistulae which were treated by means of augmentation cystoplasty or urinary diversion. All patients were evaluated regarding the time and type of surgical intervention and early and late postoperative complications, including failure of primary repair. Results. Of the 80 cases of vesicovaginal fistulae treated with definitive repair, 12 (13.3%) showed recurrence of the fistula. Early ureteric deligation and early or delayed ureteroneocystostomy or ureteric replacement were successful in all cases with ureteric injury. There was no loss of kidney function following the trauma or its repair. Conclusions. It is mandatory for gynecologists and obstetricians to pay careful attention to the anatomy of the urinary tract in order to avoid its iatrogenic injury. Endourologic means were successful in enabling first aid management of some of these injuries. Early exploration is indicated in cases of ureteric obstruction that present early after trauma. Augmentation cystoplasty, urinary diversion or ileal replacement are indicated in only a few cases.
