Rapid vascular uptake of contrast media during retrograde urethrocystography in a dog with pyogranulomatous prostatitis

A 6-year old, male, neutered German shepherd dog, with a bodyweight of 58 kg, was presented for investigation of relapsing dysuria following 2 years of adequate medical control of suspected detrusor urethral dyssynergia. During retrograde contrast urethrocystography, contrast media was visible in the prostatic vessels and caudal vena cava, suggesting rapid vascular uptake. Postmortem histopathological evaluation of the prostate was consistent with pyogranulomatous prostatitis.
