Leiomyosarcoma of the ureter.
Primary ureteral tumors occur relatively infrequently compared to tumors of the kidney and bladder. Smooth muscle tumors of the ureter are very rare and only 9 cases of leiomyosarcoma have been reported in the literature. The treatment of choice is total nephroureterectomy with en bloc excision of the tumor. Prognosis is unfavorable as indicated by the short survival of the reported cases.
