Endoscopic treatment of a ureteral inflammatory polyp in a 15‐year‐old Warmblood gelding

Summary A 15‐year‐old Warmblood gelding was presented with macroscopic haematuria and stranguria for 2 months. Cystoscopy revealed a pedunculated cauliflower‐like mass, exiting from the right ureteral orifice into the bladder. Ureteroscopy showed a right dilated ureter (2.3 mm). The ureteral lumenal mucosa was smooth, and the mass had its origin approximately 10 cm cranial from the orifice. The right kidney appeared macroscopically normal on ultrasonography. The mass was removed transendoscopically by means of a cautery snare leaving a small part at the base. Histopathological analysis identified it as a mucosal polyp. Recovery was uncomplicated and the gelding was discharged 3 days after surgery. During cystoscopic examination 5 months later, there was no sign of right ureteral inflammation, but a small stalk of the polyp was seen within the ureter.
