Urinary symptoms in women with faecal incontinence.

Abstract

Faecal incontinence (FI) is estimated to affect 8.9% of women in the United States, with a significant impact on quality of life. Our aim was to compare urinary symptoms in patients with and without FI with different degrees of severity. This prospective cohort of women presented for care at a pelvic floor disorder centre between May 2007 and January 2019. We excluded women with a history of bowel resection, prior history of pelvic organ prolapse surgery or existing prolapse symptoms reported by the patient during intake. The primary outcome was the presence of urinary symptoms in women with and without FI by validated questionnaires. A logistic regression model for association of urinary symptoms with FI was performed, adjusting for age, smoking, diabetes, prior hysterectomy and irritable bowel syndrome. A total of 2932 met inclusion criteria, and of these 1404 (47.89%) reported FI. In the univariate analysis, patients with FI were more likely to have urgency urinary incontinence (P=0.01) or mixed urinary incontinence (P<0.001), report nocturnal enuresis (P<0.001) or have leakage of urine during sex (P<0.001). In an adjusted model, FI was associated with concurrent stress (adjusted OR 1.28, P=0.034), urgency (adjusted OR 1.52, P<0.001) and mixed incontinence (adjusted OR 1.94, P<0.001). In women with pelvic floor disorders, the presence of FI is associated with a higher prevalence of urinary incontinence. Pelvic floor specialists should assess urinary incontinence symptoms along with the presence and severity of FI to provide comprehensive care and guide appropriate therapy.
