Urinary retention in a dog

Abstract

A dog with chronic urine retention is described. Neurologic disease and mechanical obstruction were ruled out, leaving a differential diagnosis that included detrusor atony and detrusor-urethral dyssynergia. Tests to differentiate between these are described, but were not performed. A final diagnosis of detrusor atony was made based on clinical observations. The diagnosis and management of detrusor atony is discussed.
