Abstract

Background: Coital incontinence is an under-reported disorder among women with urinary incontinence. Women seldom voluntarily report this condition, and as such, related data remains limited and is at times conflicting.

Aims and objectives: To investigate the incidence and quality of life in women with coital incontinence and to determine associated predictors.

Methods: This observational study involved 505 sexually active women attending the urogynecologic clinic for symptomatic urinary incontinence at a tertiary medical center. All of the patients were consulted about the experience of coital incontinence and completed evaluations including urodynamics, and valid questionnaires including the short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, the Urogenital Distress Inventory and the Incontinence Impact Questionnaire.

Results: Of these women, 281 (56%) had coital incontinence, while 224 (44%) did not. Among women with coital incontinence, 181 (64%) had urodynamic-proven stress incontinence, 29 (10%) had mixed incontinence, and 15 (5%) had detrusor overactivity. Only 25 (9%) sought consultation for this disorder before direct questioning. Fifty percent (84/281) of the women rarely or sometimes had incontinence during coitus, while 33% (92/281) often had incontinence, and 17% (48/281) always had incontinence. The frequency of coital incontinence was not different regarding the types of incontinence (p = 0.153). Women with mixed incontinence had the worst sexual quality of life and incontinence-related symptom distress. Based on univariate analysis, higher body mass index (OR 2.47, p = 0.027), and lower maximal urethral closure pressure (≤ 30 cmH2O) (OR 4.56, p = 0.007) were possible predictors for coital incontinence. Multivariate analysis showed lower MUCP was independently significant predictors (OR3.93, p = 0.042).

Conclusions: The prevalence of coital intercourse in urinary incontinence women was high. Coital incontinence in these women was associated with abnormal urodynamic diagnosis and urethral dysfunction.
