Coital Incontinence: A Multicentre Study Evaluating Prevalence and Associations.

Introduction and hypothesis: Coital incontinence (CI) is common, with a significant impact on quality of life and sexual function. This multicentre study was aimed at measuring the association between overactive bladder (OAB), stress urinary incontinence (SUI) and different aspects of CI including orgasm and penetration incontinence.

Methods: Following ethical approval, data from the electronic Personal Assessment Questionnaire-Pelvic Floor patient-reported outcome measure was collated for Urogynaecology outpatients from seven participating UK Hospitals between April 2018 and January 2022. Data were anonymised and analysed centrally using Excel.

Results: A total of 12,877 responses were obtained, of which 4,843 were valid for inclusion. 79.3% of women presented with urinary incontinence of whom 41.6% also reported CI. 96.8% of women with CI reported mixed OAB and SUI, with 2.1% and 1.1% reporting pure OAB and SUI respectively. There was a small subset (2.4%) with no overt urinary incontinence who occasionally experienced CI. Spearman's rank-order correlation demonstrated a statistically significant association between CI symptom score with both SUI (R = 0.57, p < 0.001) and OAB (R = 0.40, p < 0.001); orgasm incontinence with SUI (R = 0.49, p < 0.001) and OAB (R = 0.36, P < 0.001); penetration incontinence with SUI (R = 0.48, p < 0.001) and OAB (R = 0.35, p < 0.001).

Conclusions: Coital incontinence is experienced by 42% of women with urinary incontinence. There is a statistically significant association between both SUI and OAB with orgasm incontinence and penetration incontinence, suggesting (a) common underlying mechanism(s). Limitations of this study include the large amount of missing data and the NHS outpatient setting that limit the conclusions that can be drawn from the data.
