Predictors of unsuccessful pessary fitting in women with prolapse: a cross-sectional study in general practice

Abstract

Introduction and hypothesisPelvic organ prolapse is a common condition. There is inconsistency between predictors of unsuccessful pessary fitting in urological/gynaecological clinics. Research in general practice is scarce. The aim was to estimate the proportion of women in general practice with a symptomatic pelvic organ prolapse and unsuccessful pessary fitting, and to identify characteristics associated with unsuccessful pessary fitting.MethodsA cross-sectional study in general practice (n = 20) was carried out among women (≥55 years) with symptomatic prolapse (n = 78). Multivariate logistic regression analysis was used to identify predictors of unsuccessful pessary fitting.ResultsIn total, 33 women (42 %) had unsuccessful pessary fitting. Factors associated with unsuccessful pessary fitting were age (per year, OR 0.93 [95 % CI 0.87–1.00]), body mass index (per kg/m2, OR 1.14 [95 % CI 1.00–1.30]), and having underactive pelvic floor muscles (OR 2.60 [95 % CI 0.81–8.36]).ConclusionsPessary fitting was successful in 58 %, indicating that pessary treatment may be suitable for many, but not for all women in general practice with symptomatic prolapse. The condition of the pelvic floor probably plays a role in the success of pessary fitting, as demonstrated by the association with underactive pelvic floor muscles, and body mass index. The association with age may reflect the higher acceptance of conservative treatments for prolapse in older women. This is the first study on predictive factors for unsuccessful pessary fitting in general practice. Therefore, further research should seek to confirm these associations before we can recommend the use of this information in patient counselling.
