Coital incontinence: a factor for deteriorated health-related quality of life and sexual function in women with urodynamic stress urinary incontinence

INTRODUCTION AND HYPOTHESIS: To assess the impact of coital incontinence (CI) on health-related quality of life (HRQoL) and quality of sexual function (QSF) in women with urodynamic stress urinary incontinence (SUI). METHODS: Women were recruited for this cross-sectional study from among 289 patients with lower urinary tract symptoms, underwent clinical and urodynamic evaluation. Of these 289 women, 127 sexually active women with SUI completed the King’s Health Questionnaire (KHQ) and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ), of whom 97 were enrolled for the study. The study group comprised 53 women with CI occurring ‘sometimes’, ‘usually’ or ‘always’, and the control group comprised 44 women without CI. Total and individual domain scores were evaluated. RESULTS: CI was reported by 65.35 % of the women. The frequency of CI was correlated with lower educational level and higher body mass index (r = 0.22 and r = 0.23, respectively; p = 0.01). The KHQ results showed significantly lower HRQoL in women with CI in all domains (p < 0.05) apart from Sleep/energy’ (p = 0.054). PISQ revealed no significant differences in QSF in the Behavioral/emotive and Partner–related domains (34.3 ± 10.0 vs. 33.0 ± 12.2 and 18.0 ± 2.9 vs. 18.2 ± 3.6, respectively). Women with CI reported a significantly lower QSF in the Physical domain (29.1 ± 6.6 vs. 35.0 ± 4.6, p = 0.001), and the total PISQ score was lower but the difference was not significant (81.4 ± 14.3 vs. 86.2 ± 16.5). Total PISQ score was correlated with age (r = −0.28, p = 0.001). Women with CI were significantly more likely to admit that fear of incontinence or fear of embarrassment restricted their sexual activity (p < 0.001). CONCLUSIONS: A large percentage (65.35 %) of women with SUI reported CI, which had a negative impact on HRQoL and QSF in the Physical domain, but no significant impact on overall QSF.
