Is There a Relationship Between Overactive Bladder and Sexual Dysfunction in Women With Multiple Sclerosis?

Abstract

BackgroundLower urinary tract Symptoms (LUTS) and Sexual dysfunction (SD) are common in women with MS and affect quality of life. AimThe aim of this study was to determine the relationship between sexual dysfunction (SD) and overactive bladder in women with Multiple Sclerosis (MS). MethodsFrom January 2019 to January 2021, we evaluated 89 female MS patients admitted for LUTS in a Neuro-Urology Department. SD was investigated using the Female Sexual Function Index (FSFI). All subjects completed the Urinary Symptom Profile scale (USP) and Hospital Anxiety and Depression Scale (HAD A/HAD D). Neurological impairment was assessed using the Expanded Disability Status Scale (EDSS). All patients underwent neurological examination and urodynamic studies. Univariate analysis and Multivariate logistic regression analysis were performed to identify predictors of SD in women with MS (FSFI <26.55). OutcomesPrimary outcome was to determine the association between sexual dysfunction in women with MS and LUTS (overactive bladder, stress incontinence or voiding dysfunction). ResultsSexual dysfunction (FSFI<26,55) affected 74% of women with MS, even with low physical disabilities (EDSS<5). Univariate analysis showed that overactive bladder was more frequent in SD group, but no statistical difference was found (P < .12). No relationship was found between sexual dysfunction and stress incontinence (P = ,47), voiding dysfunction (P= 0.79) or urinary retention (P= .96). Multivariate logistic regression analysis identified overactive bladder to be an independent predictor of sexual dysfunction [aOR 0.03 (CI 0,0.98)]. Sexual dysfunction was not associated with detrusor overactivity on urodynamic studies or with impairment mobility but was strongly associated with the presence of depression (P < .01). Clinical implicationsSexual disorders in women with MS should be assessed as much as urinary disorder. Strengths and limitationsthis study included the largest cohort of women with MS. But the sample was obtained in an outpatient setting with low neurological impairment. ConclusionIn our study, SD was frequent affecting young women with no anticholinergic treatment and low physical impairment. Overactive bladder seemed to be independent predictor of sexual dysfunction. Conversely, SD was not associated with detrusor overactivity, neurological impairment, or duration of disease but was strongly associated with depression.Breton FL, Chesnel C, Lagnau P, et al.
