RESUMO
INTRODUCTION AND HYPOTHESIS: The primary objective was to determine the adverse event rate associated with pessary use. Secondary objectives were to determine discontinuation, patient satisfaction, and factors associated with adverse events. METHODS: A retrospective observational study included patients attending a nurse-led pessary clinic with ≥ 1 year follow-up. Patients were fitted with a pessary by a urogynecologist and pessary care by a nurse was performed every 3-4 months. Demographic characteristics, pessary fitting, adverse events, their management and discontinuation were recorded. Pearson Chi-square and Fisher exact tests assessed the association between predetermined risk factors and pessary complications or discontinuation. Relative risk and 95% confidence intervals were computed. RESULTS: 215 women were followed for a mean (standard deviation) of 4.4 (1.9) years. Mean age was 73.8 (8.7) years. Adverse event rate was 83.7%; most commonly vaginal discharge, vaginal bleeding and erosions. Women with cardiovascular risk factors were less likely to develop pessary-related adverse events (79.7% vs. 91.9%, p = 0.03). Gellhorn and donut pessaries were more commonly associated with pessary erosions than ring with support pessaries or incontinence rings (RR 2.37 [1.67; 3.38]). Thirty-five (16.3%) women discontinued pessary use at a mean of 3.3 (1.7) years after initial fitting. Having a pessary erosion was not associated with discontinuation (p = 0.698), but recurrent erosions were (p = 0.012). CONCLUSION: Adverse events were common among women continuing to use pessaries past 1 year, but adherence and satisfaction rates remained high after 4.4 years. Pessary type and absence of cardiovascular factors were associated with pessary-related adverse events.
