[Problems of late formation of a radiation-induced vesico-vaginal fistula. Case report].

Described in this paper is a large urinary fistula which developed 38 years after Wertheim's radical hysterectomy and percutaneous irradiation. The patient's condition was improved by supravesical urine discharge through anastomosis between ureter and sigma. Discussed are conditions required for adequate uretero-sigmoidostomy. Good therapeutic results may justify, in certain cases, uretero-sigma anastomosis, despite a history of irradiation and poor general condition.
