Urinary tract fistulas following gynaecological surgery

Urinary tract fistulas are a relatively uncommon but important complication of gynaecological surgery. Between 1980 and 1995 we identified 17 patients who developed a urinary tract fistula after gynaecological surgery. Seven of the patients had surgery performed for neoplastic disease but none of these patients received adjuvant radiotherapy before the formation of the fistula. There were 12 vesicovaginal fistulas and five ureteric fistulas. Four of the vesicovaginal fistulas were repaired by the vaginal approach and five vesicovaginal fistulas were repaired by the abdominal route. Three vesicovaginal fistulas were treated by catheterisation alone. Two of the 17 patients took medicolegal action. Early recognition and repair of urinary tract fistulas is recommended. Repair of vesicovaginal fistulas by the vaginal approach is advised. The litigious nature of this distressing condition is lessened when early primary closure is successful.
