Abstract / Summary
Urinary incontinence (UI) adversely affects women’s quality of life and sexual health; however, whether female sexual function differs according to UI subtype remains unclear. This cross-sectional study evaluated 93 women with stress (SUI, n = 45), urgency (UUI, n = 24), or mixed urinary incontinence (MUI, n = 24), classified using clinical assessment and multichannel urodynamic evaluation. Sexual function was assessed using the Female Sexual Function Index (FSFI); total FSFI score was the primary outcome. No statistically significant between-group difference was detected in total FSFI score (Kruskal-Wallis H = 3.65, p = 0.161; ε² = 0.018) or individual domains. UUI showed a numerically lower median total FSFI score than SUI and MUI (3.4 vs. 17.7 and 15.1), but pairwise Hodges-Lehmann 95% confidence intervals crossed zero. Sexual activity during the preceding four weeks was not recorded separately; therefore, low FSFI scores may partly reflect sexual inactivity and should not be interpreted as diagnostic estimates of female sexual dysfunction prevalence. These findings do not establish equivalence among UI subtypes. Larger studies incorporating validated UI severity measures and explicit assessment of recent sexual activity are needed.
