Chronic urinary retention after radical cystectomy and orthotopic neobladder in women: Risk factors and relation to time

To investigate the long-term cumulative incidence of chronic urinary retention (CUR) after radical cystectomy (RC) and orthotopic neobladder (ONB) in women and the possible risk factors.

We retrospectively analyzed a prospectively evaluated cohort of women for whom RC and ONB were performed.

Patients in CUR were evaluated for the cumulative incidence of CUR using Kaplan-Meier curve and for the possible risk factors using log rank and Cox regression analysis.

A total of 234 women with mean age ± SD of 52.3 ± 9 years and a median (range) of follow-up of 92 (12-247) months were included. The incidence of CUR increased with time, where 12 (5.2%), 21 (8.97%), 35 (14.9%), 53 (22.6%), and 56 (24%) patients started clean intermittent catheterization in 1, 2, 2 to 5 years, 5 to 10 years, and after 10 years of follow-up, respectively. In univariate and multivariate analysis, diabetes mellitus and urethral Kock pouch were independent predictors of CUR development (HR [95% CI] = 2.45 [1.2-5.1], and 2.1 [1.05-4.2], P = 0.01 and 0.03, respectively). Genital- sparing RC and surgical modification to provide pouch back support were independent factors that reduce CUR development (HR [95% CI] = 9.3 [1.25-69.9], and 2.1 [1.19-3.9], P = 0.02 and 0.01, respectively).

The incidence of CUR after RC and ONB in women increases with time even after 10 years of follow-up. Presence of diabetes mellitus increases the risk of CUR development. Genital-sparing RC and modification to prevent CUR reduced the likelihood of CUR development.
