Prolonged second stage effect on pelvic floor dysfunction: a follow up survey to a randomized controlled trial.

BACKGROUND

Pelvic floor dysfunction is a group of disorders that can significantly impact quality of life due to persistent urinary and anal incontinence. Data evaluating the effect of prolonged second stage of labor and postpartum pelvic floor dysfunction is heterogenous and limited.

OBJECTIVE

To evaluate whether extending the length of labor in nulliparous women with prolonged second stage affects the presence of self-reported pelvic floor dysfunction after a randomized controlled trial of prolonged second stage.

STUDY DESIGN

We conducted a planned follow up survey to our randomized controlled trial of prolonged second stage of labor using the Pelvic Floor Distress Inventory-20 (PFDI-20). The primary outcome was the PFDI-20 summary score. Secondary outcomes included urinary and fecal incontinence, prolapse, and patient satisfaction. Women surveyed were nulliparous patients with epidural anesthesia, previously enrolled in a randomized controlled trial that assigned them to

RESULTS

Thirty-four of the seventy-eight women responded to the survey (43.6%). 17 women (50.0%) were from the extended labor group and 17 from the usual labor group (50.0%). Maternal demographic data were not significantly different between groups. The PFDI-20 summary score was 13.8 ± 23.3 in the extended labor group and 13.1 ± 20.9 in the usual labor group (

CONCLUSION

Extending the length of labor in nulliparas with singleton gestations, epidural anesthesia, and prolonged second stage did not have an impact on PFDI-20 scores at 12-36 months postpartum. However, our study was underpowered to detect small, but potentially clinically important, differences.
