摘　　要：目的:探讨盆底超声检查定量评估不同分娩方式对初产妇前盆腔功能的近期影响。方法:收集2022年6月-2023年12月本院超声医学科行盆底检查的初产妇102名临床资料,根据产妇不同分娩方式分为经阴道分娩组(n=58)和剖宫产组(n=44),均分娩后6~8周行盆底超声检查,比较两组盆底超声检查参数以及前盆腔功能异常发生率。结果:两组初产妇年龄、体质指数及新生儿身长无差异(P>0.05)。经阴道分娩组和剖宫产组静息状态下超声参数膀胱颈距离(25.1±4.4 mm、25.6±4.2 mm)°、膀胱后角(117.6±6.8、118.2±7.5)°、尿道倾斜角(29.1±2.4、28.2±2.5)°比较均无差异(P>0.05)。经阴道分娩组最大Valsalva状态下超声参数膀胱颈下降距离(27.17±7.38mm)、膀胱后角(132.91±10.57)°、尿道倾斜角(53.82±12.35)°均高于剖宫产组[15.26±6.14mm、(124.93±9.18)°、(34.71±10.02)°];经阴道分娩组膀胱膨出发生率(53.5%)高于剖宫产组(27.3%),尿道内口扩张发生率(19.0%)高于剖宫产组(4.6%)(均P<0.05)。结论:盆底超声检查可有效、定量评估不同分娩方式产妇前盆腔结构变化及盆腔功能,阴道分娩者盆腔结构和功能变化大于剖宫产者。Objective:To investigate the influence of the different delivery modes of primiparas on their short-term anterior pelvic function evaluated by the pelvic floor ultrasonography quantitatively.Methods:The clinical data of 102 primiparas who had undergone the pelvic floor examination by ultrasound from June 2022 to December 2023 were collected.According to the different delivery modes,these primiparas were divided into group A(58 primiparas with vaginal delivery)and group B(44 primiparas with cesarean section).The short-term anterior pelvic function of the primiparas in the two groups were evaluated quantitatively by pelvic floor ultrasound.The values of the pelvic floor ultrasound parameters and the incidence of abnormal anterior pelvic function of the primiparas were compared between the two groups.Results:There were no significant differences in the maternal age,the body mass index and the neonatal length of the primiparas between the two groups(P>0.05).There were no significant differences in the bladder neck distance(25.1±4.4 mm vs.25.6±4.2 mm),the posterior bladder angle value(117.6±6.8 vs.118.2±7.5),the urethral tilt angle value(29.1±2.4°vs.28.2±2.5°)of the primiparas between the two groups(P>0.05).The values of the maximum Valsalva ultrasound parameters,such as the bladder neck descent(27.17±7.38mm),the posterior bladder angle(132.91±10.57°)and the urethral tilt angle(53.82±12.35),of the primiparas in group A were significantly higher than those(15.26±6.14mm,124.93±9.18 and 34.71±10.02°)of the primiparas in group B.The incidence of the cystocele(53.5%)of the primiparas in group A was significantly higher than that(27.3%)of the primiparas in group B,and the incidence of the internal urethral orifice dilatation(19.0%)of the primiparas in group A was significantly higher than that(4.6%)of the primiparas in group B(all P<0.05).Conclusion:The pelvic floor ultrasound can effectively and quantitatively evaluate the changes of the anterior pelvic structure and function of the primiparas with the diff
