经阴道超声评估产后妇女盆腔器官位置及盆底肌改变的价值分析

Transvaginal ultrasound assessment of pelvic organ position and pelvic floor muscle changes in postpartum women

目的分析经阴道超声观察产后妇女盆腔器官位置及盆底肌变化的价值。方法选取受检者81例,其中43例产后女性为产后组,38例已婚未育女性为对照组,采用经阴道超声在静息状态及缩肛状态下观察盆底器官位置及运动,测量尿道倾斜角(UIA),尿道膀胱后角(PUA)及宫颈外口位置(CMP)并比较;并用经会阴三维超声采集静息状态及瓦式位(Valsalva)下肛提肌裂孔图像,测量其前后径L及面积A并比较。结果产后组在静息及缩肛状态下UIA及PUA较对照组增大,CMP降低,肛提肌裂孔L及A均大于对照组,差异均有统计学意义(P<0.05)。结论经阴道超声可在不同状态下多方位观察产后妇女盆腔器官位置及肛提肌裂孔改变,从而评价妊娠和分娩对盆腔器官及盆底肌的影响。

Objective To observe the changes of pelvic organ position and pelvic floor muscles in postpartum women by transvaginal ultrasound.Methods 81subjects were selected,including 43 postpartum women divided into postpartum group and 38 married childless women as control group.Transvaginal ultrasound was used to observe the position and movement of pelvic organs in resting state and rectum exercise state.Measure the urethral inclined angle(UIA),posterior urethroversical angel(PUA),and the cerval mouth position(CMP),compare them in groups. And use the perineal 3D ultrasound to collect the levator ani muscle hole's image under the rest state and the Valsalva.The anteroposterior dimension(L) and the area A are measured and grouped for comparison. Results In the postpartum group,the UIA and PUA were increased compared with the control group and the CMP was decreased.The L and A of the levator ani muscle were larger than the control group(P<0.05). Conclusion Transvaginal ultrasound can observe the changes of pelvic organ position and levator ani muscle in postpartum women through different states.The effects of pregnancy and childbirth on pelvic organs and pelvic floor muscles can be evaluated.
