RESUMEN
OBJECTIVE: The aim of the study was to evaluate the associated factors associated with pessary dislodgment in women with advanced pelvic organ prolapse (POP). METHODS: A cohort study with women (N = 98) with advanced POP who chose conservative treatment with ring pessary between December 2016 and 2018 identified by screening. Demographic data, history of POP, urinary, and/or bowel symptoms were collected. A medical visit was scheduled 3 and 6 months after pessary insertion to evaluate symptoms (vaginal discharge, bleeding, pain, discomfort, new-onset urinary, or fecal problems) and any pessary dislodgment. Two groups were created (women who were able to retain the pessary versus who were not able), and univariate and multivariate analysis were performed to look for risk factors for pessary dislodgment. Women who requested to have their pessaries removed during the 6-month follow-up were excluded. RESULTS: Ninety-three women included in the study, 78 successfully continued to use the pessary at 6 months, and 15 had pessary dislodgment (16.1%). Demographic characteristics were similar between the treatment group and the control group. After multivariate analysis, women who had their pessaries dislodged presented higher rates of previous surgery (odds ratio = 8.11; 95% confidence interval = 2.09-31.58; P = 0.003) with advanced Pelvic Organ Prolapse Quantification system staging (odds ratio, 13.41; confidence interval, 1.97-91.36; P = 0.008). CONCLUSIONS: The presence of advanced apical POP and previous POP surgery are risk factors for ring pessary dislodgment. This information should guide physicians for counseling patients before pessary insertion.
