Four hundred and thirty two patients with superficial bladder cancer were treated at Okayama University Hospital between 1961 and 1992. Among them, 14 patients (3%) developed upper urinary tract recurrence. We demonstrated that the presence of a tumor around the ureteral orifice, the presence of carcinoma in situ (CIS), the presence of vesicoureteral reflux (VUR), a decrease in bladder capacity, multifocal tumors and a tumor of Grade 3 were all risk factors. Prognosis of upper urinary tract recurrence was poor and the 5-year survival rate was 39%. Periodical examination and early diagnosis and treatment for high risk cases are necessary in order to improve their prognosis.
