Predictors for long-term adherence to vaginal pessary in pelvic organ prolapse: a prospective study.

Abstract

The objective was to investigate the rate of adherence to pessary treatment for pelvic organ prolapse (POP), to identify factors associated with long-term (longer than 1 year) use of vaginal pessaries in Brazilian women with POP and its impact on quality of life (QoL). A prospective observational study assessed 247 consecutive women candidates for a pessary to manage symptomatic POP. Patients were fitted with a ring pessary and follow-up visits were performed at 1, 6, and 12months. Pessary complications and reasons for discontinuation were recorded. Prolapse Quality of Life Questionnaire (P-QoL) was applied at baseline and after 1 year of treatment. We used a logistic regression model for the analyses, with p < 0.05 for significance. A total of 236 women were included in the study, of whom 110 (46.6%) maintained the pessary treatment for longer than 12months. The main reason for pessary discontinuation was the patient opting for surgery (50.8%). Vulvovaginitis was the main long-term complication (44.5%), followed by vaginal ulceration (16.4%) and urinary urgency (10%). No prior hysterectomy (OR = 2.26; 95% CI 1.19-4.31), vaginal estrogen use (OR = 1.94; 95% CI 1.06-3.52), and mean age (OR = 1.03; 95% CI 1.01-1.06) were variables associated with long-term use of vaginal pessary (p < 0.05 for all). Total P-QoL score significantly changed with pessary use (519.1 at baseline and 260 after 12-month treatment, p < 0.00). Our study suggests that no prior hysterectomy, the local estrogen therapy, and age might be factors associated with use of a ring vaginal pessary for longer than 1 year. Long-term pessary users had a significant improvement in their quality of life.
