摘要
目的探讨单胎和双胎妊娠女性盆底肌形态特征的三维盆底超声特点。方法选取2016年12月至2017年12月于丽水市中医院检查的96例妊娠女性临床资料进行分析,其中50例单胎妊娠者设为对照组,46例双胎妊娠者设为研究组,均予以晚孕期三维超声检查,比较两组盆底肌收缩,Valsalva动作及静息状态下的冠状径、矢状径及肛提裂孔面积。结果两组Valsalva动作状态下冠状径比较无显著性差异(t=1.746,P>0.05),研究组盆底肌收缩、静息状态下冠状径均显著大于对照组(t值分别为22.078、24.679,均P<0.01)。两组孕妇盆底肌收缩、Valsalva动作及静息状态下矢状径比较均无显著性差异(t值分别为1.354、0.691、0.132,均P>0.05)。研究组在Valsalva动作、盆底肌收缩及静息状态下的肛提肌裂孔面积均显著大于对照组(t值分别为7.148、6.534、8.379,均P<0.05)。结论三维盆底超声检查显示,单胎妊娠与双胎妊娠者在盆底肌形态方面具显著性差异,双胎妊娠女性骨盆变化更大。
Objective To study the characteristics of three-dimensional ultrasonography of pelvic floor muscles in women with singleton and twin pregnancy. Methods The clinical data of 96 pregnant women who had received examinations in Traditional Chinese Medicine Hospital of Lishui City from December 2016 to December 2017 were analyzed. Among them, 50 cases with singleton were set as control group and the other 46 cases of twin pregnancy were assigned as study group. Three-dimensional ultrasonography was performed in both groups in late pregnancy. The coronal diameter, sagittal diameter and levator ani muscle fissure area under pelvic muscle contraction, Valsalva maneuver and rest state were compared between two groups. Results There was no significant difference in coronary diameter under Valsalva maneuver between two groups （t = 1. 746, P〉0.05）, but the coronary diameter under pelvic floor muscle contraction and rest state in the study group were significantly greater than those of the control group （t value was 22.078 and 24.679, respectively, both P〈0.01）. There was no significant difference in sagittal diameter under Valsalva maneuver, pelvic floor muscle contraction and rest state between two groups （t value was 1.354, 0.691 and 0.132, respectively, all P〉0.05）. The levator ani muscle fissure area under Valsalva maneuver, pelvic floor muscle contraction and rest state in the study group were significantly greater than that of the control group （t value was 7.148, 6.534 and 8.379, respectively, all P 〈 0.05）. Conclusion Three-dimensional ultrasonography of pelvic floor shows significant differences in the morphology of pelvic floor muscle between cases of singleton and twin pregnancy, with a greater change in females with twin pregnancy.
