Urethrorectal fistula in a Labrador puppy

摘要

A 5-month-old entire male Labrador retriever puppy was diagnosed with congenital urethrorectal fistula based on positive contrast abdominal radiography. Antimicrobial therapy was used to treat a clinically asymptomatic lower urinary tract infection prior to surgical correction. The fistula itself was ligated via a perineal approach. The clinical signs resolved immediately after surgery and had not recurred at telephone update 5 months later.
