【摘要】 目的：采用三維超声评价绝经前女性的肛提肌功能，并分析其与雌激素水平的关系。方法：选取2017年1月-2019年1月于本院进行健康体检的60例女性。按照是否绝经分为对照组（绝经）和研究组（绝经前），各30例。分别采用三维超声进行检查，静息时、Valsalva时分别测量肛提肌裂孔前后径、面积、肛提肌长度，测定雌激素水平，并采用Pearson相关性分析肛提肌功能与雌激素水平的关系。结果：静息时、Valsalva时，研究组肛提肌裂孔前后径均短于对照组，肛提肌裂孔面积均小于对照组，差异均有统计学意义（P<0.05）;研究组肛提肌面积改变量小于对照组、雌激素水平高于对照组，差异均有统计学意义（P<0.05）;相关性分析显示，经前女性雌激素水平与肛提肌裂孔前后径、肛提肌裂孔面积、肛提肌长度、肛提肌裂孔前后径改变量、肛提肌裂孔面积改变量均呈负相关（P<0.05），与肛提肌长度改变量不相关（P>0.05），绝经后女性雌激素水平与肛提肌各指标均无相关性（P>0.05）。结论：三维超声能够通过测量肛提肌裂孔前后径、面积及肛提肌长度评价肛提肌功能，绝经前女性雌激素水平与肛提肌功能存在相关性，雌激素水平越低则肛提肌功能越差，绝经后女性雌激素与肛提肌功能不相关。

Relationship between Estrogen Level and Levator Ani Muscle Function in Premenopausal Women Evaluated by Three-dimensional Ultrasound/LI Xinxin.//Medical Innovation of China，2019，16（18）：-131

【Abstract】 Objective：To evaluate the levator ani muscle function in premenopausal women by three-dimensional ultrasound，and to analyze the relationship between levator ani muscle function and estrogen level.Method：A total of 60 women who underwent a physical examination in our hospital from January 2017 to January 2019 were selected.According to whether or not menopause，they were divided into control group（menopause）and study group（premenopause），30 cases in each group.Three-dimensional ultrasound was used to examine the levator ani muscle，the anterior and posterior diameters，area and length of levator ani muscle hiatus were measured at rest and Valsalva，estrogen level was measured，pearson correlation was used to analyze the relationship between levator ani muscle function and estrogen level.Result：At rest and Valsalva，the anterior and posterior diameters of levator ani hiatus in study group were shorter than those of control group，the area of levator ani hiatus were smaller than those of control group，the differences were statistically significant（P<0.05）.The area change of levator ani muscle in study group was less than that of control group and estrogen level was higher than that of control group，the differences were statistically significant（P<0.05）.The correlation analysis showed that the level of estrogen was negatively correlated with the anterior and posterior diameters of levator ani muscle hiatus，the area of levator ani muscle hiatus，the length of levator ani muscle hiatus，the change of anterior and posterior diameters of levator ani muscle hiatus and the change of levator ani muscle hiatus area（P<0.05），but not with the change of levator ani muscle length（P>0.05）.There was no correlation between estrogen level and levator ani index in postmenopausal women（P>0.05）.Conclusion：Three-dimensional ultrasound can evaluate levator ani muscle function by measuring the anterior and posterior diameters，area and length of levator ani muscle hiatus，there is a correlation between estrogen level and levator ani muscle function in premenopausal women，the lower the estrogen level，the worse the levator ani muscle function，there is no correlation between estrogen and levator ani muscle function in postmenopausal women.
