Primary carcinoma of ureter. Report of 27 new cases

A retrospective analysis of 27 cases of primary carcinoma of the ureter is presented. The ages of the patients ranged from forty-two to eighty-three years, with the highest incidence between the fifth and seventh decades. Males were more frequently affected than females, and the tumors were usually found in the lower third of the ureter. Hematuria and flank pain were the presenting symptoms in the majority of cases. Poorly differentiated invasive tumors had poor prognosis when compared to well-differentiated noninvasive lesions. Total nephroureterectomy with excision of bladder cuff is the preferred treatment for ureteral carcinoma in view of the high rate of ipsilateral tumor recurrence.
