为探究盆底超声检查评估分析不同的分娩方式对女性晚期妊娠和产后盆底结构、功能及预后效果的影响,本研究选取收治的100例顺利生产的孕妇作为本实验研究对象,根据分娩方式的不同将其分为自然分娩组与剖宫产组,各组50例。在两组孕妇妊娠晚期和产后分别通过盆底超声检测盆底结构和功能(膀胱旋转角,尿道膀胱后角,肛提肌裂孔面积和肛提肌裂孔周长);以及在产后第6～8周和盆底康复治疗后进行压力性尿失禁发生率调查问卷表填写及护垫实验。研究发现,阴道自然分娩比选择性剖宫产对妊娠晚期和产后孕妇盆底结构和功能造成的损伤更为显著;盆底损伤较严重的孕妇压力性尿失禁程度同样较严重;而盆底康复治疗成功的压力性尿失禁患者,盆底超声检测发现孕妇产后盆底结构和功能得到有效改善。本研究结果说明,盆底超声评价在检测不同分娩方式对妊娠晚期和产后孕妇的盆底结构、功能及预后存在一定的预测和预防作用。

To explore the effect of different deliver y modes on the structure, function and prognosis of female pelvic floor. A total of 100 pregnant women who had successfully given birth were selected as the subjects of this experiment. According to the different modes of delivery, they were divided into natural delivery group and cesarean section group with 50 cases in each group. Pelvic floor ultrasound was used to detect pelvic floor structure and function in two groups of pregnant women at the late and postnatal stages respectively(the bladder rotation angle,the posterior urethral vesical angle, and the area of the anus muscle hiatus and the circumference of the anus muscle hiatus). Questionnaires on the incidence of stress urinary incontinence and pad test were completed at 6～8 weeks postpartum and after pelvic floor rehabilitation. Natural vaginal delivery is more harmful to pelvic floor structure and function in late pregnancy and postpartum women than selective cesarean section. The degree of stress urinary incontinence in pregnant women with severe pelvic floor injury is also serious. Pelvic floor ultrasonography showed that the structure and function of the pelvic floor of pregnant women with stress urinary incontinence were improved effectively. Pelvic floor ultrasonography can predict and prevent the pelvic floor structure, function and prognosis of late pregnancy and postpartum pregnant women.
