The defunctionalized bladder

Abstract

Supravesical urinary diversion without cystectomy is a common procedure performed to manage a variety of lower urinary tract pathologies. The purpose of this article is to review the complications associated with the bladder left in situ and to relate this to the female patient. Complications related to the defunctionalized bladder include pyocystis, hemorrhage, pain/spasm and neoplastic transformation. The defunctionalized bladder also has implications for sexual function, pregnancy and undiversion. The risk factors for complications are chronic infection, inadequate drainage, interstitial cystitis and previous irradiation. The incidence of neoplastic change in the defunctionalized bladder is low, but long-term follow-up is advised, as carcinoma could develop many decades after diversion. Sexual function following urinary diversion is better preserved when the bladder is retained.
