Sexual Disorders in Women with Overactive Bladder and Urinary Stress Incontinence Compared to Controls: A Prospective Study

Introduction and Hypothesis Female urinary incontinence (UI) has a negative impact on sexual function and sexual quality of life (QoL) in women. But there is still no consensus on the type of UI or the prevalence of sexual dysfunction (SD). The aim of the study was to evaluate sexual disorders in women with overactive bladder (OAB) compared to patients with urinary stress incontinence (SUI) and healthy controls. Materials and Methods 106 women presenting to a urogynecological outpatient clinic (referral clinic) were investigated using standardized questionnaires and the Female Sexual Function Index (FSFI-d). All 65 incontinent women underwent a full urodynamic examination; the controls (31) were non-incontinent women in the same age range who came for routine check-ups or minor disorders not involving micturition or pelvic floor function. Women with mixed urinary incontinence, a history of previous medical or surgical treatment for UI, recurrent urinary tract infections, previous radiation therapy or pelvic organ prolapse of more than stage 2 on the Pelvic Organ Prolapse Quantification (POP-Q) system were excluded. Results 100 questionnaires could be evaluated (94.3%). Thirty-four women had urinary stress incontinence, 35 had OAB, 31 were controls. Mean age was 56 years, with no significant differences between groups. The scores of the questionnaire ranged from 2 to 35.1 points. The median score of OAB patients was significantly lower (17.6) than the median score of the controls (26.5; p = 0,004). The stress-incontinent women had a score of 21.95, which was lower than that of the controls but statistically non-significant (p = 0.051). In all subdomains, the OAB patients had lower scores than the stress-incontinent women and significantly lower values than the control group. Most striking was the impairment of “sexual interest in the last 4 weeks”. The figure for “none or almost no sexual activity” was 80% for the OAB group, 64.7% for the group of stress-incontinent women and 48% for the control group. Incontinence during intercourse was reported by one OAB patient and 4 stress-incontinent women but did not occur in the control group. Conclusions There is a high prevalence of SD in women with urinary incontinence. Patients with OAB reported a greater negative impact on sexual function and had significantly lower scores for the FSFI questionnaire than patients with stress incontinence or controls.
