目的运用经会阴超声评估不同分娩方式对女性后盆腔器官的影响。方法对自然分娩100例、剖宫产术后100例及未孕100例妇女运用腔内探头经会阴对后盆腔器官位置、结构进行观察,评估不同分娩方式对后盆腔器官结构和功能的影响。结果最大Valsalva动作下,所有受检者肛直肠角均较静息状态下缩小,3组受检者在最大Valsalva动作下和静息状态下肛直肠角大小差异无统计学意义(P>0.05);会阴体运动过度、直肠膨出、肛门内外括约肌损伤发生率顺产组高于未孕组和剖宫产组。结论不同分娩方式导致女性后盆腔器官结构及功能不同程度的损伤。
Objective To evaluate the effects of different modes of delivery on pelvic organ in women after perineal ultrasonography. Methods 100 cases of natural childbirth, 100 cases of post-cesarean section and 100 cases of non-pregnant women were treated with intraluminal probe through the perineum to observe the position and structure of the pelvic organs and evaluate the effect of different modes of delivery on pelvic organ structure and function. Results Under the maximal Valsalva motion, the anus and rectum angles of all the subjects decreased compared with the resting state. There was no significant difference in the size of the anorectal horn among the three groups under the maximal Valsalva motion and resting state (P> 0.05) ; Perineal body hyperactivity, rectal prolapse, internal and external anus anal sphincter injury incidence in the cesarean section than non-pregnant group and cesarean section group. Conclusions Different modes of delivery lead to different degrees of damage to the pelvic organ structure and function in women.
