Elderly are often the population affected by bladder cancer. Physician must consider not only a patient's chronologic age but also physiologic age and associated medical conditions. Although radical cystectomy remains the treatment of choice for muscle invasive bladder cancer, it has a well-recognized risk of perioperative complications and mortality. Multidisciplinary oncogeriatric evaluation is necessary to detect associated comorbidities, and to improve oncologic decision and surgical outcomes. Radical cystectomy with ileal conduit is recommended in elderly. Indications of conservative treatments depend on local extension, haematuria, and metastasis.
