[Indication of neobladder replacement in patients undergoing radical cystectomy for bladder cancer]

Neobladder replacement has become an important procedure in the patient undergoing radical cystectomy for invasive bladder cancer. It yields postoperatively excellent quality of life in these patients. The indications of the patients selection have not been established, since long-term clinical results have not been presented and some issues such as urethral recurrence of the original disease, growth of the cancer from the neobladder made of the gastrointestinal tract and influences arising from orthotopic micturition are still unclear. We reviewed the reports describing neobladder replacement in the patients undergoing cystectomy for the bladder cancer. At present the criteria of patients selection described by most authors can be summarized as follows, (1) male patients, (2) patients having an available gastrointestinal tract for reconstructing the neobladder, (3) patients having a good renal function and liver function and could tolerate for the surgery and (4) patients with no evidence of disease in their urethra and prostate (direct invasion of the disease). As to carcinoma in situ within the bladder, some authors included their indication and the others contraindication.
