Polypoid cystitis in a male entire springer spaniel puppy

Abstract

A 14-week-old entire male springer spaniel was presented for haematuria. Investigations identified polypoid cystitis. Medical management failed to improve the clinical signs, and the dog underwent surgical excision of the bladder polyps at eight months old. Histopathological examination of the polyps identified granulomatous foci containing crystalline material. Eighteen months after surgery, the dog has had no further episode of haematuria and repeat ultrasound-documented resolution of the lesions. This is the youngest reported case of polypoid cystitis in dogs and the first report of this lesion associated with crystal inclusions within the polyps.

Early-Onset Asymptomatic Polypoid Cystitis in Two Adolescent Male Beagle Dogs

“…The shape of the polyps is also thought to favor urine retention and bacterial adhesion to the mucosa, instigating a vicious cycle of infection-proliferation-inflammation. 3,11 While canine polypoid cystitis typically occurs in adult dogs, Ruiz et al 8 reported the occurrence of the disease in a 14-week-old springer spaniel puppy that presented due to recurrent hematuria. In that previous case, bacterial urine culture was negative, however, urinalysis intermittently revealed the presence of struvite crystals.…”
