Primary neoplasm of the ureter: a review of twenty-eight cases.

Twenty-eight patients with primary ureteral neoplasms of which 7 of a benign type were reviewed retrospectively. Sixteen of these patients underwent segmental resection, with a 2-year survival of 81% and with no ureteral recurrence. Eleven other patients underwent a complete nephroureterectomy with bladder cuff excision with a subsequent 2-year survival of 63.6%. We believe that segmental resection is indicated in all low-grade and low-stage lesions and with a small chance of recurrence.
