RESUMO
There are few reports in the literature of carcinoma developing in the post-diversionary bladder. The sixth such case is reported and the pertinent literature is reviewed. All cases of carcinoma in defunctionalized bladders have been associated with chronic inflammation of the bladder and all tumors became apparent within 4 years of diversion. Simple cystectomy at the time of diversion should be considered for patients with a long history of bladder inflammation.
