[Radical cystectomy for invasive tumors of the bladder in patients over 70 years of age].

The authors present a series of forty patients operated for invasive bladder tumors by radical cystectomy. All patients were older than 70 and had a complicated medical history. Mortality was 1 in 40 and the morbidity was low. The conclusion is that radical cystectomy is a safe procedure in elderly patients.
