acquired vesicovaginal fistula secondary to ovariohysterectomy in a bitch: a case report

A seven-year-old bitch was referred for investigation of a two-month history of strangury. Clinical signs had developed within two days of elective ovariohysterectomy. Ultrasonographic and radiographic examinations suggested stump pyometra or cervical granuloma and vesicovaginal fistula. Two laparotomies were performed to repair the adhesions, but no reduction in clinical signs was observed. Medical treatment was performed. Eight months later, the animal was admitted for examination and it appeared to be healthy but still had signs of strangury.
