Defecatory dysfunction and anal incontinence symptoms among women with pelvic organ prolapse: 5-year retrospective study in a tertiary center

OBJECTIVE: To investigate the prevalence of DD and AI with POP symptoms in females attending a urogynecology clinic, and to identify factors associated with DD and AI in POP symptoms patients.

METHODS: Computer-based medical records of women with POP symptoms attending a urogynecology clinic in a referral tertiary center between January 2016 and December 2020 were reviewed. Demographic data were collected. Selected defecatory dysfunction (DD) and anal incontinence (AI) were recorded. The associations between patient characteristics, site and severity of prolapse, and DD and AI symptoms in POP patients were investigated for identified associated factors.

RESULTS: The mean age of the 754 participants was 65.77 ± 9.44 years. Seven hundred and fifteen (94.83%) were menopause. The prevalence of DD and AI in patients with POP symptoms was 44.03% (332/754) and 42.04% (317/754) according to the PFBQ and medical history records, respectively. Advanced posterior wall prolapse (OR 1.59, 95% CI 1.10-2.30) and wider GH (OR1.23, 95% CI 1.05-1.43) were identified as risk factors for DD by multivariate analysis. Additionally, single-compartment prolapse (OR 0.4, 95% CI 0.21-0.76) and a stronger pelvic floor muscle assessed with brink score (OR 0.94, 95% CI 0.88-0.98) are protective factors for AI.

CONCLUSION: DD and AI are prevalent among women with POP symptoms who visit a urogynecology clinic. DD should be evaluated in women with POP symptoms especially in women with increased genital hiatus and point Ap beyond the hymen. To prevent AI, women with POP should be encouraged to perform pelvic floor muscle training in order to increase pelvic floor muscle strength.
