[Follow up of patients with bladder cancer treated with radical cystectomy].

Radical cystectomy provides excellent local control of the disease in cancer patients, although specific 5-year mortality is about 50%. Additionally, nearly half the patients show complications after surgery usually due to urinary by-pass. Patients should undergo periodical monitoring for life. For rescue treatment to be as effective as possible, follow-up schemes should allow for early detection of relapsing-recurrent tumours, metastasis and complications. Knowledge of the "natural evolution" in these patients allows to optimise the frequency of visits and complementary examinations based on each patient's risk at specific time-points. Cost-efficacy relationship will also be optimised. We analyze here the current literature and our own experience of what we know as "natural evolution" of these patients and propose a follow-up scheme for patients with cancer of the bladder treated with radical cystectomy and urinary by-pass.
