Polyp in urinary bladder of a dog - a case report

Abstract

Polyps are benign formations rarely found in the urinary tract both in veterinary medicine and human medicine. The etiology was not identified, but it is believed to occur by recurrent infection of the urinary tract, characterizing a disease called polypoid cystitis. It was described in this report a case found in a neutered 11 years-old bitch Cocker Spaniel with a history of hematúria for two years. It was identified a urinary infection by Serratia spp and the ultrassond examination showed two irregular pedunculated masses in the cranioventral portion and thickening of the bladder wall. The animal was underwent parcial cystectomy to remove the masses where it was observed other small formations near the same region; the material was referred to histopathological examination to confirm the diagnosis of bladder polyps. For treatment of disease, in addition to surgical excision, the infection should be treated properly. The prognosis is good, but cases of recurrence may occur especially when the removal is made only from the bladder mucosa.
