  • Abstract
  • Look Inside

A 63-year-old man, who had undergone right simple nephrectomy for calculous pyonephrosis in 1981, passed a stone in February, 1993, and complained of perineal discomfort in August, 1993. CT scan showed a mass lesion on the right side posterior to the bladder. Explora-tory operation revealed the mass originating from right ureteral stump, involving the right seminal vesicle. The mass was removed en bloc with partial cystectomy. The pathological diagnosis was primary well-differentiated squamous cell carcinoma. Primary tumors of ureteral stumps are very rare, and this is the 13th case report in the Japanese literature.
