[Urinary bladder fistulas].

During the period 1978 to 1991, 19 patients were treated for fistula of the urinary bladder, 12 of the fistulas were enterovesical, four vesicovaginal, one vesicouterine and two vesicocutaneous. Most of them occurred after diverticulitis or operation, or when the patient suffered from a malignant disease. Four patients received conservative treatment. One patient decided against an operation, two were inoperable, and one fistula closed with use of an indwelling catheter. 15 were operated on. 12 extirpations of fistula were carried out. Additional resection of intestine was performed in seven patients and hysterectomia in two patients. Other procedures included two enterostomias and one ileum bladder. In ten patients postoperative courses were uneventful. Four patients died during the first month after operation. One suffered a relapse, and another damage to the nerves of the bladder.
