Extravasation of contrast medium following retrograde pyelography may occur when excessive pressure is used during injection of the contrast medium, direct trauma during manipulation of the ureteral catheter or pre-existing ureteral disease. Extravasation of contrast medium occurring in a ureteral tumour is rare. A case where extravasation of contrast medium was observed during retrograde pyelography due to extensive invasion of the ureter by a primary ureteral tumour is reported.
