A 63-year-old male with transitional cell carcinoma of the bladder underwent total cystectomy. Five years later sequential excretory urography and urinary cytologic examination revealed tumor recurrence in the left pelvis and ureter; left nephroureterectomy was performed in July, 1984. In December, 1985, he complained of macrohematuria and urinary cytology was positive. Ileal conduitgraphy showed filling defects at the bilateral uretero-ileal anastomosis, where two papillary lesions were disclosed by endoscopic examination. In January, 1986, total extirpation of the ileal conduit and reconstruction of a new ileal conduit was performed. Macroscopically the two lesions were found to be a papillary tumor at left uretero-ileal anastomosis and a polypoid tumor distal to right uretero-ileal anastomosis. Histological examination revealed both tumors to be grade II transitional cell carcinoma. This rare case is discussed and the literature is reviewed.
