Cheung RYK, et al. - This work was planned to assess clinical risk factors for dislodgment of vaginal pessary within one year in women with symptomatic pelvic organ prolapse. Findings suggested that clinical predictors for dislodgment of a vaginal pessary were higher staging of prolapse, larger genital hiatus and apical compartment prolapse. Researchers, however, suggested offering a vaginal pessary to women with advanced stage of prolapse or predominant apical compartment prolapse as around 50% of them were able to keep the vaginal pessary up to one year.
