采用盆底超声检查和盆底肌力评估方法分析不同分娩方式对女性盆底功能的影响.[方法]选取2017年6月至2018年6月本院收治的63例初产妇为本研究对象,根据不同分娩方式将产妇分为剖宫产组(n=33)和自然分娩组(n=30).另选取同期来我院进行健康体检的女性28例作为对照组.对比两组产妇盆底超声检查与盆底肌力评估指标变化情况,并将其数据与对照组受试者进行对比.[结果]在静息状态下盆底超声检查显示,自然分娩组与剖宫产组的膀胱颈角度、膀胱颈移动度和膀胱旋转角度均明显高于对照组,而自然分娩组又高于剖宫产组,其差异均有显著性(P<0.05);盆底肌力评估结果表明,自然分娩组与剖宫产组盆底肌力持续收缩力与盆底肌力最大收缩力均低于对照组,而自然分娩组又低于较剖宫产组,其差异也具有统计学意义(P<0.05).[结论]盆底超声机检查与盆底肌力评估在对分娩后产妇压力性尿失禁和器官脱垂有一定的预测价值.“,”Toexploretheeffectofdifferentdelivery methodsonpelvicfloorfunctionbypelvic floorultrasoundandpelvicfloormusclestrengthevaluation.[Methods]Sixty-threecasesofprimiparaadmittedto ourhospitalfrom June2017toJune2018 wereselectedastheresearchobject.Accordingtodifferentdelivery methods,thepuerperasweredividedintocesareansectiongroup (n=33)andnaturaldeliverygroup (n=30).
