| 目的 经会阴三维超声对妊娠晚期女性盆底结构的观察，通过测量肛提肌裂孔面积来探讨妊娠对盆底解剖结构的影响。方法 应用经会阴三维超声，对盆底功能正常组孕妇106例及存在压力性尿失禁异常组孕妇20例进行盆底结构观察，Valsalva动作时动态三维超声成像测量肛提肌裂孔面积(cm2)及超声断层成像观察肛提肌形态有无断裂。 结果 盆底功能异常组Valsalva动作后肛提肌裂孔面积(cm2)均明显大于正常组，有统计学差异（P＜0.05）。 结论 肛提肌裂孔面积此指标能反映妊娠期女性盆底结构改变情况，有助于评估肛提肌损伤。 |

| Abstract: |
| Objective Observation of the pelvic floor structure in the third trimester of pregnancy by three dimensional ultrasound, and to explore the influence of pregnancy on the anatomical structure of the pelvic floor.
Methods Observed the Pelvic floor structure by the transperineal two dimensional and three dimensional Sonographic examination ，which in normal group (106 cases) and in abnormal group(20 cases)of pelvic floor function. During the Valsalva movement,measure the area of levator hiatus (cm2) via dynamic three-dimensional,and to observe the morphology of the anal sphincter by Ultrasonic tomography.
Results The area of levator hiatus in the Pelvic floor dysfunction group were significantly higher than that in the normal group (P < 0.05).
Conclustion We consider that the area of levator hiatus can better reflect the changes in the structure of women''s pelvic floor during pregnancy,and be useful to evaluate the injury of the levator hiatus. |
| Key words: Female pelvic floor dysfunction The transperineal three dimensional Sonographic examination Late trimester of pregnancy levator hiatus |
