The ureteral stump after nephroureterectomy.

Herein we review 70 cases of transitional cell carcinoma of the upper urinary tract. When complete nephroureterectomy was not performed transitional cell carcinoma developed in 30 per cent of the remaining ureteral stumps. Single incision nephroureterectomy did not include the intramural ureter in 50 per cent of the cases in which it was performed. When nephroureterectomy is selected as treatment for carcinoma of the renal pelvis or ureter a cuff of bladder, which includes the ureteral orifice, should be removed. A second incision may be required for adequate exposure.
