The association of fecal incontinence, constipation, and pelvic pain with the course of lower urinary tract symptoms in community-dwelling men and women

Abstract

Background: Fecal incontinence, constipation, and pelvic pain are common pelvic floor symptoms (PFS), and frequently coexist with lower urinary tract symptoms (LUTS). However, their association with the longitudinal trajectory of LUTS have not been well described. Our objective was to investigate the association between PFS and the course of LUTS in community-dwelling men and women.

Methods: Men and women aged ≥16 years were invited to participate in a prospective observational cohort study. At baseline, and after 12 and 24 months, participants filled in the International Consultation on Incontinence Modular Questionnaire (ICIQ-MLUTS and ICIQ-FLUTS) for men and women respectively, the Wexner incontinence and constipation scale, and a questionnaire on pelvic pain. Generalized estimating equations were used to examine the association between change scores in defecation problems and pelvic pain, and LUTS change scores.

Results: A total of 694 men and 997 women gave informed consent, with 417 men and 566 women included in the analysis. The mean age was 63.2 ± 12.7 years for men and 58.6 ± 14.8 years for women. The study showed minor changes in LUTS scores over the 0-12 and 12-24-month periods. Generalized estimating equations revealed positive associations between changes in constipation and fecal incontinence and LUTS changes in both sexes. For instance, a one-point increase in Wexner constipation score was associated with 0.376 (0.165, 0.587) points higher LUTS change in men and 0.223 (0.109, 0.336) points in women during the 0-12-month follow-up. However, associations between changes in pain and LUTS scores varied across sexes and time periods.

Conclusions: We observed minor changes in LUTS over time and weak associations between PFS and LUTS that sometimes differed between males and females, emphasizing the need for sex-specific considerations. These insights can provide valuable guidance for the development of targeted prevention trials, ultimately aiming to enhance overall pelvic health and patient well-being.
