摘　　要：目的探讨应用经会阴三维超声及TUI成像技术检测不同分娩方式对盆底肛提肌的影响。方法选取2014年8月—2016年8月分娩的产妇200例,分为选择性剖宫产组(85例)和阴道分娩组(115例),将阴道分娩组根据术中有无侧切分为阴道侧切组(65例)和阴道无侧切组(50例),同时选择同期就诊的80例未生育妇女(自愿者)作为对照组,利用三维成像及TUI成像技术测量相关指标。结果阴道无侧切组、阴道侧切组、剖宫产组肛提肌裂孔的横径、周长、前后径、面积较对照组均显著要高(P<0.05),而阴道侧切组显著高于其他3组(P<0.05),阴道分娩组两个亚组及剖宫产组肛提肌厚度均显著低于对照组(P<0.05),阴道分娩组两个亚组均显著低于剖宫产组(P<0.05);阴道分娩组与剖宫产组肛提肌损伤率比较无统计学差异(P>0.05)。结论相较于剖宫产,阴道分娩方式在改变肛提肌形态及完整性上更明显,且相比于阴道无侧切者,阴道分娩侧切产妇的盆底损伤更明显。Objective To investigate the effect of different delivery methods on the levator ani muscle of the pelvic floor by transperineal three-dimensional ultrasound and TUI imaging. Methods 200 cases of pregnant women from August2014 to August 2016 in our hospital were divided into selective cesarean section group（ n = 85） and vaginal delivery group（ n= 115）. The vaginal group,according to the intraoperative lateral segmentation,was further divided into vaginal lateral incision group（ n = 65） and vaginal delivery without lateral incision group（ n = 50）. At the same time,select 80 cases of nulliparous women（ volunteers） as control group,relevant indicators by three-dimensional imaging and TUI imaging technique.Results The vaginal delivery without lateral incision group,lateral incision group vaginal delivery and cesarean section group levator hiatus diameter,anteroposterior diameter,perimeter and area were significantly higher than the control group（P〈0. 05）,and vaginal delivery side cut was significantly higher than the other three groups（P〈0. 05）,vaginal delivery in two sub-group and cesarean section group of levator ani muscle thickness were significantly lower than the control group（P〈0. 05）,vaginal delivery in two sub groups were significantly lower than that in the cesarean section group（P〈0. 05）;vaginal delivery group of levator ani muscle injury rate was significantly higher than that in the cesarean section group（ P〈0. 05）; There was no significant difference in the rate of levator ani muscle injury in vaginal delivery group（ P〈0. 05）.Conclusion Compared with cesarean section,vaginal delivery is more obvious in changing the morphology and integrity of levator ani muscle,and vaginal delivery is more obvious than that of vaginal incision.
