EMPHYSEMATOUS CYSTITIS AND BLADDER TRIGONE DIVERTICULUM IN A DOG

A 14-month-old, male German shepherd dog was evaluated for chronic, re current Escherichia coli urinary tract infection, An initial diagnosis of emphysematous cystitis was made, which resolved with appropriate a ntibacterial therapy. The urinary tract infection, however, did not re solve 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 repa ir of the diverticulum, and reviews the literature with regard to both congenital bladder trigone diverticulum and emphysematous cystitis, T he former has never been documented in the dog and the latter is an un usual finding in a non-diabetic dog.
