【摘要】 目的：探讨会阴三维超声的作用原理及在评估产后盆底功能障碍（PFD）患者盆底功能改善中的应用价值。方法：将我科118例产后PFD患者随机分为对照组与观察组，各59例。对照组患者行常规健康教育和保健操锻炼，观察组患者行系统康复训练。两组患者敢于前后，均经会阴三维超声检查，比较两组患者静息、缩肛、Valsalva动作状态下的盆膈肌裂孔前后径、左右径、面积及肛提肌厚度，并测量Valsalva动作下膀胱颈活动度（BND）。结果：干预后，静息状态下及Valsalva动作下，观察组盆膈肌裂孔前后径、左右径、面积均小于对照组（P <0.05），肛提肌厚度均大于对照组（P<0.05）。而干预后，缩肛状态下，两组各指标比较，P> 0.05。Valsalva动作时，观察组患者BND水平低于对照组（P <0.05）。结论：经会阴三维超声可有效评估康复训练后产后PFD患者的盆底结构及功能，对判断PFD产妇盆底功能的改善效果具有重要的作用。更多还原

【Abstract】 Objective: To investigate the principle of perineal three-dimensional ultrasound and its application value in evaluating the improvement of pelvic floor function in patients with postpartum pelvic floor dysfunction(PFD).Methods: 118 patients with postpartum PFD in our department were randomly divided into control group and observation group, 59 cases in each group. Patients in the control group received routine health education and health exercises, while patients in the observation group received systematic rehabilitation training. The anterior and posterior diameter, left and right diameter, area of pelvic diaphragm hiatus and levator ANI thickness were compared between the two groups under resting, anal contraction and Valsalva action, and the range of motion(BND) of bladder neck under Valsalva action was measured. Results: After the intervention, the anterior and posterior diameter, left and right diameter and area of pelvic diaphragm hiatus in the observation group were smaller than those in the control group at rest state and under Valsalva action(P<0.05), and the thickness of levator ANI muscle in the observation group was larger than that in the control group(P<0.05). After intervention, the indexes of the two groups were compared in the anal contraction state, P > 0.05.During Valsalva action, the BND level in the observation group was lower than that in the control group(P<0.05).Conclusion: Three-dimensional transperineal ultrasound can effectively evaluate the pelvic floor structure and function of postpartum PFD patients after rehabilitation training, and plays an important role in judging the improvement effect of pelvic floor function in PFD women.更多还原
