摘要
目的:探讨实时剪切波弹性成像技术(SWE)在评价盆底肌肉功能中的效能。方法:选取61例女性患者为研究对象,均接受问卷调查、盆底超声检查、盆底肌力测试及耻骨直肠肌(PR)剪切波弹性成像检查。以肌力是否正常分为肌力正常组(n=22)和肌力异常组(n=39)。利用SWE获取两侧PR静息状态及最大收缩状态耻骨下支附着处和中部的剪切波速度值(SWV)及杨氏模量值(YM),取其平均值,分别计算两种状态所得SWV及YM的差值,分析盆底肌力变化与PR不同状态的SWV、YM及其差值的关系。结果:女性患者PR相同部位最大收缩状态SWV及YM大于静息状态,差异有统计学意义(P<0.05)。静息状态下,肌力正常组PR相同部位SWV及YM与肌力异常组比较,差异无统计学意义(P>0.05)。最大收缩状态下,肌力正常组PR两侧耻骨下支附着处及左侧中部SWV、YM与肌力异常组比较,差异有统计学意义(P<0.05)。两组间PR相同部位比较,肌力正常组PR两侧耻骨下支附着处两种状态SWV及YM的差值较肌力异常组大,差异有统计学意义(P<0.05)。两组PR中部SWV及YM的差值比较,差异无统计学意义(P>0.05)。结论:SWE能够敏感探测到PR力量的改变,PR两侧耻骨下支附着处弹性值的变化对评价盆底肌肌力变化更有价值。
Objective:To investigate the application value of real-time shear-wave elastography(SWE)in the evaluation of pelvic floor muscle function.Methods:61 female patients who volunteered to participate in this research project and met the conditions were selected as the research objects.All patients received a questionnaire survey,pelvic floor ultrasonography,pelvic muscle strength test,and shear wave elastography of puborectalis(PR).They were divided into normal group(n=22)and abnormal group(n=39)according to whether the muscle strength was normal.SWE was used to obtain the shear wave velocity(SWV)and Young s modulus(YM)the attachment site of puborectalis(PR)to inferior ramus of pubis and the middle of PR in the resting and maximum contraction states bilaterlly,calculated the average value.The difference between SWV and YM of the two states was calculated respectively.The relationship between the changes of pelvic floor muscle strength and SWV,YM and their differences in different states of PR were analyzed.Results:The SWV and YM of the same part of PR in female patients in the maximal contraction state were significantly higher than those in the resting state(P<0.05).There was no statistically significant difference in SWV and YM in the same position at the resting state of PR between normal muscle strength group and abnormal muscle strength group(P>0.05).In the contractile state,the SWV and YM of the attachment of the inferior ramus of PR bilaterlly and middle part of left PR in the normal muscle strength group were compared with the abnormal muscle strength group,and the differences were statistically significant(P<0.05).The difference of SWV and YM in the same part of PR at the two states between the two groups were compared,and the difference values of SWV and YM of the attachment of the inferior pubic rami on both sides of PR in the normal muscle strength group was greater than the abnormal muscle strength group significantly(P<0.05).There was no significant difference in SWE and YM between the two groups in the middle of PR(P>0.05).Conclusion:SWE can detect the changes of PR strength sensitively.The change of elastic value at the attachment of inferior pubic ramus on both sides of PR is more valuable for evaluating the change in pelvic muscle strength.
