Abstract:
A 14-month-old, male German shepherd dog was evaluated for chronic, recurrent Escherichia coli urinary tract infection. An initial diagnosis of emphysematous cystitis was made, which resolved with appropriate antibacterial therapy. The urinary tract infection, however, did not resolve and on further investigation a bladder trigone diverticulum was evident, thought to be congenital in origin. This report describes the apparent ultrasonographic and radiological changes, and surgical repair of the diverticulum, and reviews the literature with regard to both congenital bladder trigone diverticulum and emphysematous cystitis. The former has never been documented in the dog and the latter is an unusual finding in a non-diabetic dog.
