Orthotopic Detaenial Sigmoid Neobladder after Radical Cystectomy: Technical Considerations, Complications and Functional Outcomes

Purpose: In recent years the orthotopic neobladder has gained increasing popularity in patients who undergo radical cystectomy. However, there are only a few reports of orthotopic neobladders reconstructed from the sigmoid without detubularization. We investigated the complications and functional outcomes of the orthotopic sigmoid neobladder reconstructed using our detaenial technique.Materials and Methods: We performed a retrospective study of the detaenial sigmoid neobladder in 210 consecutive patients who underwent radical cystectomy at our institution from January 2003 to March 2010. ANOVA was used to investigate urodynamic finding differentials with time. Univariable and multivariable analyses were done to determine factors influencing continence.Results: Median followup was 48 months. Early complications (90 days or less) were observed in 65 patients (31%). Late complications (greater than 90 days) were observed in 45 patients (21.5%). Five-year daytime and nighttime complete continence rates were 7...
