Traumatic Rectovesicular Fistula in a Dog

A 7 mo old intact male Australian cattle dog presented for evaluation of a suspected urethrorectal fistula after being examined by the primary veterinarian for leaking of urine from the rectum at rest and when posturing to urinate. Advanced imaging identified a caudally retroflexed urinary bladder, several healing pelvic fractures, and a rectovesicular fistula. Primary surgical repair of the fistula was performed. The dog recovered well from surgery and was urinating and defecating normally as of 5 mo after the operation. This is the first report of a traumatic rectovesicular fistula in the veterinary literature.
