Recurrent urothelial tumors following surgery for transitional cell carcinoma of the upper urinary tract.
A retrospective analysis of 74 cases of transitional cell carcinoma of the renal pelvis and ureter treated at this institution over the past 30 years is presented. When nephrectomy alone or incomplete nephroureterectomy was performed, subsequent transitional cell carcinoma developed in 30% of the ureteral stumps. Subsequent bladder carcinoma occurred in 25% of the patients with primary upper urinary tract carcinoma. The type of initial surgery performed did not appear to influence this incidence of subsequent bladder tumors. Contralateral upper urinary tract carcinoma developed in only one patient. When nephroureterectomy is performed for carcinoma of the renal pelvis and ureter, a cuff of bladder that includes the ureteral orifice should be removed to obviate recurrent disease in the ureteral stump. Since single-incision nephroureterectomy did not include the intramural ureter in 50% of the cases in which it was performed, a second incision may be required for adequate exposure.
