Voiding Function in Women with Orthotopic Neobladder Urinary Diversion

PurposeMost long-term morbidity after radical cystectomy is related to the urinary diversion or reconstruction. While there are benefits to an orthotopic neobladder, there can be a substantial risk of voiding dysfunction in women. We examine the prevalence of postoperative voiding complications in women who underwent orthotopic neobladder diversion.Materials and MethodsWe identified all women who underwent radical cystectomy and orthotopic neobladder for bladder cancer at our institution from 1996 to 2011 (51) and included patients with regular clinic followup (49). The presence and severity of incontinence and hypercontinence were evaluated at routine clinic visits. Unadjusted analyses were performed to measure the association between patient variables and voiding symptoms, with p <0.05 considered significant.ResultsDaytime incontinence, nighttime incontinence and hypercontinence were reported by 43%, 55% and 31% of women, respectively. A neobladder-vaginal fistula developed in 3 women (6%). On unadjusted analysis having daytime incontinence was associated with a concurrent or previous hysterectomy (p = 0.031), but not with age, disease stage, preoperative incontinence, year of surgery or sparing the vaginal wall. The severity of daytime incontinence was associated with preoperative incontinence only (p = 0.02). The presence and severity of nighttime incontinence were associated with patient age only (p = 0.013, p = 0.005, respectively). Hypercontinence was not associated with any variable.ConclusionsAmong women with orthotopic neobladder after radical cystectomy we identified a significant prevalence of voiding dysfunction. We recommend preoperative discussion of these possible complications with any woman interested in orthotopic neobladder to establish realistic expectations. For properly selected women who understand these risks, orthotopic neobladder may be an appropriate diversion choice.
