The aim of the study is to analyse urethral mobility and excursion of the pubo-rectal angle, using perineal ultrasound, after normal vaginal delivery and water delivery.
A total of 52 primiparous women were enrolled: 25 who had delivery in water (W Group), 27 who had delivery without using water (NW Group). Every woman underwent perineal ultrasound assessment at 6 months after having given birth. The following parameters were assessed: urethral mobility during Valsalva's manoeuvre, movement of the puborectal sling angle during contraction of the levator ani muscle.
Data obtained show that the urethral mobility during Valsalva's manoeuvre is higher in the W Group (34.9 degrees) in comparison to the NW Group (29.5 degrees), without statistically significant differences. The excursion of the pubo-rectal sling angle resulted lower in the W Group (8.7 degrees) than in the NW Group (11.0 degrees), without statistically significant differences.
The present study found no statistically differences in pelvic floor, using perineal ultrasound, between water and "non-water" delivery.
本研究旨在利用会阴超声分析正常阴道分娩和水中分娩后尿道活动度及耻骨直肠角的偏移情况。
共纳入52名初产妇，其中25名进行水中分娩（W组），27名未进行水中分娩（NW组）。每位产妇在产后6个月接受会阴超声评估。评估以下参数：瓦尔萨尔瓦动作时的尿道活动度、提肛肌收缩时耻骨直肠吊带角的移动情况。
获得的数据显示，瓦尔萨尔瓦动作时W组的尿道活动度（34.9度）高于NW组（29.5度），但无统计学显著差异。耻骨直肠吊带角的偏移在W组（8.7度）低于NW组（11.0度），无统计学显著差异。
本研究发现，利用会阴超声，水中分娩和“非水中”分娩在盆底方面无统计学差异。
