✦ Synopsis

Sixty-nine patients who underwent nephroureterectomy for upper urinary tract transitional cell carcinoma were included in the study. The following data were collected for each patient: grade and stage of renalhreteral tumor, tumor location, timing of tumor appearance and recurrence in the bladder, grade and stage of each of the recurrent tumors, and number of recurrences. Follow-up ranged between 2 and 15 years. Thirty-three patients (47.8%) developed metachronous bladder tumors. The appearance of the bladder tumors was related to tumor grade and multifocality of the upper urinary tract TCC. Of the 33 patients, 19 had I tumor appearance in the bladder, 6 had 2 recurrences, and 8 had 3 recurrences. The 5-year survival rate for patients with no subsequent bladder tumors was 57% compared to 22% for those who had subsequent tumors. It is concluded that the appearance of bladder tumors following nephroureterectomy characterizes a group of patients with biologically more active disease with unfavorable prognosis.
