Evaluating the short-term effect of delivery mode on female anterior compartment of pelvic floor

Abstract

Objective To dynamically observe and evaluate the position and movement of anterior pelvic floor organs in vaginal delivery and selective caesarean section primipara with translabial two-dimensional(2D) ultrasound, and discuss the short-term effect of delivery mode on the anterior compartment of pelvic floor. Methods Translabial 2D ultrasound was performed on selective caesarean section and vaginal delivery primipara in 6-8 weeks. The position of bladder, the existence of bladder neck funneling were observed, and the mobility of bladder neck and the urethral rotation angle were measured during maximum Valsalva maneuver. Results The mobility of bladder neck was larger in vaginal delivery group than selective caesarean section group during maximum Valsalva maneuver. The rates of bladder neck funneling, cystocele and stress urinary incontinence were higher in vaginal delivery group. Conclusions Translabial 2D ultrasound could dynamically observe and evaluate the position and movement of anterior pelvic floor organ, which could be used to assess the effect of delivery mode on anterior compartment of pelvic floor. The short-term effect of vaginal delivery on anterior compartment of pelvic floor is greater than that of selective cesarean delivery.
