Can we predict the need for clean intermittent catheterization after orthotopic neobladder construction?

Abstract

Introduction: We aimed to identify peri-operative and pathologic characteristics that may predict the need for clean intermittent catheterization (CIC) following radical cystectomy (RC) with orthotopic neobladder (ONB) in order to improve patient counseling on choice of urinary diversion. Materials and Methods: Between July 2004 and February 2013, all patients who underwent RC with ONB were identified. Peri-operative clinical and pathological features were evaluated and correlated with patients reported need for CIC. The independent T-test was performed for continuous variables and Chi-square test was performed for categorical variables. Multivariate forward stepwise logistic regression analysis was used to identify variables that correlated with need for CIC after ONB. Results: During the study period, 114 patients underwent RC with ONB creation. On univariate analysis, patients with higher body mass index, younger age, and non-vaginal or non-nerve-sparing procedures were more likely to require catheterization for complete emptying. Multivariate analysis demonstrates that conservative surgery (nerve sparing in males or vaginal sparing in females) was associated with a significantly lower rate of requiring CIC (Odds Ratio [OR] 0.20, P < 0.01). Surprisingly, older age was also associated with a slightly lower, but statistically significant, rate of requiring CIC (OR 0.92,P < 0.01). Conclusions: When counseling patients regarding the different types of diversions after RC, the potential need for long-term CIC after ONB must be discussed. The clinical factors that appear to increase the need for CIC include non-conservative RC (non-nerve sparing in males and non-vaginal sparing in females) and, to a certain degree, younger age.
