| 目的 采用剪切波弹性成像评价耻骨直肠肌的收缩功能。方法 收集盆腔器官脱垂患者28例，其中POP-Q Ⅲ级组和POP-Q Ⅳ级组各14例；另收集同期健康志愿者28名作为对照组。采用剪切波弹性成像分别在静息及最大缩肛状态下测量各组两侧耻骨直肠肌前、中、后部杨氏模量值，并计算缩肛前后杨氏模量值的差值。对上述指标进行统计学分析。结果 各组最大缩肛状态的杨氏模量值均较静息状态增大（P均<0.05）。POP-Q Ⅲ级组和Ⅳ级组静息状态、最大缩肛状态杨氏模量值和缩肛前后杨氏模量值的差值与对照组比较差异均有统计学意义（P均<0.05）；POP-Q Ⅲ级组与Ⅳ级组间静息状态、最大缩肛状态杨氏模量值及其差值差异无统计学意义（P均>0.05）。结论 盆腔器官脱垂患者存在耻骨直肠肌收缩功能减低；剪切波弹性成像可用于检测盆腔器官脱垂患者耻骨直肠肌收缩功能异常。 |

| Objective To evaluate the contraction function of puborectalis (PR) with shear wave elastography (SWE). Methods Twenty-eight patients with pelvic organ prolapse (POP-Q Ⅲ group and POP-Q Ⅳ group, each n=14) and 28 healthy volunteers (control group) were enrolled. The Young's modulus of PR in the front, middle and back of pubic rectal muscles of each group at resting and maximal rectal state were measured with shear wave elastography, and then were statistically analyzed. Results Young's modulus of maximum rectal state of each group was higher than that of resting state (all P<0.05). At resting and maximal rectal state, the Young's modulus and their differences in POP-Q Ⅲ group and POP-Q Ⅳ group were significantly different compared with control group (all P<0.05), but those in POP-Q Ⅲ group and POP-Q Ⅳ group were not (all P>0.05). Conclusion Decrease of PR systolic function can be observed in patients with pelvic organ prolapse, and SWE can be used to detect abnormal function of PR systolic function. |
