经会阴超声评估不同分娩方式对女性前盆腔的短期影响

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

目的：应用经会阴二维超声动态观察和评估经阴道分娩和选择性剖宫产初产妇张力期前盆腔器官的位置及运动情况，探讨不同分娩方式对女性前盆腔的短期影响。方法选取产后6-8周选择性剖宫产和阴道分娩初产妇，经会阴超声观察张力期膀胱的位置、尿道内口是否呈漏斗状开放，测量膀胱颈移动度、尿道旋转角度，并进行两组比较。结果阴道分娩组与选择性剖宫产组比较，张力期膀胱颈移动度大，尿道内口漏斗状开放、膀胱脱垂以及压力性尿失禁发生率高，差异均具有统计学意义。结论经会阴超声可通过观察前盆腔器官的参数变化来评估不同分娩方式对前盆腔的影响。阴道分娩对女性前盆腔的短期影响大于选择性剖宫产。

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.
