An inverted papilloma of the ureter with ipsilateral hydronephrosis was found in a 77-year-old man who had a history of prostatic carcinoma. Inverted papilloma of the urothelium is a rare lesion, with the vast majority of cases being found in the bladder. To date none has been documented in the ureter.
