Quantitative evaluation on puborectalis function in patients with pelvic organ prolapse using shear wave elastography / 中国医学影像技术

ABSTRACT

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 Youngs 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.
