Summary

Predicting major levator trauma before birth is challenging. A lower body mass index was the only identified antepartum predictor, suggesting current methods are insufficient for accurate risk assessment.

Area of Science:

  • Obstetrics and Gynecology
  • Pelvic Floor Disorders
  • Maternal Fetal Medicine

Background:

  • Levator trauma is a significant cause of pelvic floor dysfunction after childbirth.
  • Accurate antepartum prediction of levator trauma could enable targeted interventions.
  • Current methods for predicting levator trauma are not well-established.

Purpose of the Study:

  • To determine the feasibility of predicting major levator trauma antepartum.
  • To identify potential demographic and ultrasound predictors of levator avulsion.

Main Methods:

  • Prospective longitudinal study of 488 nulliparous women.
  • Interviews and 4D transperineal ultrasound at 36-38 weeks gestation and 4 months postpartum.
  • Correlation of antepartum variables with postpartum diagnosis of levator avulsion.

Published on: September 20, 2018

Main Results:

  • 367 women completed postpartum assessment; 14% (34/367) had levator avulsion.
  • No association found between avulsion and maternal age, family history of cesarean, hiatal dimensions, muscle strain, bladder neck descent, or subpubic arch angle.
  • Lower body mass index was the sole statistically significant antepartum predictor of levator avulsion (P = .005).

Conclusions:

  • Antepartum prediction of major levator trauma appears difficult or impossible with current methods.
  • Future research should explore modifications to obstetric practices and antepartum interventions.
  • Focus on interventions applicable to the general pregnant population is recommended.
