Effect of postpartum pessary use on pelvic floor function: a prospective multicenter study.

Purpose: This study evaluates the restitution of pelvic floor function in postpartum women using the Restifem® pessary in a preventive and therapeutic approach.

Methods: In this multicentre study all postpartum women independently of their parity, mode of delivery and existing pelvic floor symptoms were offered to use the Restifem® pessary from 6 weeks postpartum for 3 to 6 months. They completed the validated German pelvic floor questionnaire (GPFQpp) via online survey at 6 weeks, 6 months and 12 months postpartum and were divided, by their own choice, into users and non-users of the pessary.

Results: Initially 857 women were enrolled. After 6 weeks 137 pessary users and 133 non-users, after 12 months 53 pessary users and 45 non-users submitted a completed questionnaire. Pessary users had significantly higher (worse) scores in all domains of the GPFQpp at 6 weeks postpartum. At 12 months postpartum pessary users still had a significantly higher bladder score, compared to non-users. There was a greater improvement in the bladder score (p = 0.005) and the pelvic organ prolapse score (p < 0.001) from 6 weeks to 12 months postpartum, among pessary users compared to non-users.

Conclusion: Pessary users had a significantly greater improvement in pelvic floor function from 6 weeks to 12 months postpartum, compared to non-users. This effect might be in part due to wearing the pessary but also due to greater scope for recovery, given the higher level of pelvic floor dysfunction in the pessary user group.

Trial registration: The trial was registered in the German Clinical Trials Register (DRKS00024733) on 19 of April 2021.
