title: Carcinoma of the renal pelvis and ureter following bladder carcinoma: frequency, risk factors and clinicopathological findings.
abstract: We followed 657 primary bladder carcinoma patients for at least 10 years or until death. Subsequent carcinomas of the renal pelvis or ureter were found in 11 patients (1.7 per cent) 10 months to 13 years after the primary bladder tumor. In 3 patients the tumors were diagnosed or suspected by excretory urography, while in 5 the tumors were not found until autopsy. Four patients had undergone cystectomy and 9 had multiple bladder tumors at the initial assessment or during followup. The initial or recurrent bladder tumor involved the ipsilateral ureteral orifice in 6 patients. We conclude that in bladder cancer patients routine excretory urography is not indicated in the absence of upper urinary tract symptoms but it should be performed in selected patients, that is those with multiple and recurrent bladder tumors or tumors involving the ureteral orifices, or those with a previous cystectomy.
