【摘要】：目的采用经会阴实时三维超声动态观察和评估产后女性盆底三腔室器官的位置及肛提肌裂孔面积。方法选取年龄、体质量指数匹配的60名产妇(产后组)和35名未育女性(对照组),采用经会阴超声分别在静息状态及瓦氏动作下测量膀胱、子宫颈、直肠壶腹部的最低点与参考线(耻骨联合后下缘的水平线)之间的距离,采用实时三维超声测量瓦氏动作下肛提肌裂孔面积,并进行统计学分析。结果产后组在静息状态和瓦氏动作下膀胱及子宫颈的最低点位置均低于对照组(P均0.05),直肠壶腹部位置在静息状态下两组差异无统计学意义(t=0.405,P=0.398),在瓦氏动作下产后组低于对照组(t=17.378,P0.001)。产后组在静息状态和瓦氏动作下肛提肌裂孔面积均大于对照组(t=11.253、9.625,P均0.001)。结论经会阴实时三维超声可动态观察女性盆底三腔室器官的位置、运动情况及肛提肌裂孔面积,从而评价妊娠和分娩对盆底支持组织的影响。
[Abstract]:Objective to observe and evaluate the position of three-chamber organs of pelvic floor and the area of levator ani fissure in postpartum women by transperineal real-time three-dimensional ultrasound. Methods 60 pregnant women (postpartum group) and 35 unbred women (control group) matched with age and body mass index were selected to measure bladder and cervix by perineum ultrasound under resting state and Watt's action respectively. The distance between the lowest point of the rectum ampulla and the reference line (the horizontal line of the posterior inferior margin of the pubic symphysis) was measured by real-time three-dimensional ultrasound and the area of the inferior levator ani muscle fissure was measured and analyzed statistically. Results the lowest position of bladder and cervix in postpartum group was lower than that in control group (P < 0.05). There was no significant difference between the two groups in the position of ampulla in resting state. The postpartum group was lower than that in control group (17.378P0.001). The area of levator ani muscle fissure in postpartum group was larger than that in control group in resting state and Vapor movement. Conclusion the position, movement and area of levator ani muscle fissure of female pelvic floor three-chamber organ can be dynamically observed by real-time three-dimensional ultrasound through perineum, and the effect of pregnancy and delivery on pelvic floor supporting tissue can be evaluated.
