Predictors for dislodgment of vaginal pessary within one year in women with pelvic organ prolapse

To identify clinical risk factors for dislodgment of vaginal pessary within one year in women with symptomatic pelvic organ prolapse.

Study design

This was a prospective observational study which recruited consecutive women with symptomatic pelvic organ prolapse in a tertiary urogynecology center. Basic demographics, clinical symptoms and staging of pelvic organ prolapse were assessed. A vaginal pessary was offered where appropriate.

Main outcome measures

Demographics and clinical parameters were compared between women who were able to use a vaginal pessary for one year and those whose pessaries were dislodged within one year.

Results

A total of 779 women were recruited and had a vaginal pessary inserted. Of them, 528 women, with a mean age of 64.7 (SD 10.1) years, returned for one-year follow-up; 177 (33.5%) had had their pessary dislodged within one year and 351 (66.5%) had been able to retain the pessary. Stage III or IV prolapse (OR 1.76), prolapse predominant at the apical compartment (OR 2.14) and larger genital hiatus (OR 1.63) were factors associated with dislodgment of the vaginal pessary. Age, body mass index, previous hysterectomy and short vagina were not associated with dislodgment. Nevertheless, 47.6% of women with stage III/IV prolapse could still keep the pessary for one year.

Conclusion

Higher staging of prolapse, larger genital hiatus and apical compartment prolapse are clinical predictors for dislodgment of a vaginal pessary. Despite this, nearly half of women with stage III/IV prolapse were able to use a vaginal pessary for one year. Therefore, a vaginal pessary should be offered despite their staging of prolapse.
