Summary: A 5-year-old male Dwarf rabbit and 4-year-old female Mini-Rex rabbit were evaluated because of anorexia and urine scalding of the perineum. Abdominal radiography revealed a diffuse increase in the opacity of the urinary bladder attributable to urinary sludge. In 1 rabbit, abdominal ultrasonography revealed several mass-like lesions protruding from the mucosal surface into the lumen of the urinary bladder. Rabbits were anesthetized, and cystoscopy was performed with a rigid 2.7-mm, 30° endoscope. Histologic analysis of tissue samples obtained through the cystoscope operating channel revealed findings consistent with polypoid cystitis.
