Abstract:
Objective To compare the early effects on pelvic floor function of three modes of labor:natural delivery,cesarean section and forceps-assisted delivery.Methods Fifty-eight cases of women who underwent transperineal three-dimensional pelvic floor ultrasonography at 6 weeks postpartum at Obstetrics and Gynecology Hospital,Fudan University from Jan 2019 to Jan 2020 were collected and divided into three groups:the natural birth group(n=22),cesarean section group(n=9),and forceps group(n=27).General data such as age,parity,birth order,neonatal weight,and pelvic floor ultrasonography findings were collected.Results The differences in age,gestational week at delivery,newborn weight and number of pregnancies among the three groups were not statistically significant.In pelvic floor ultrasonography,it was found that in the resting state,the cervix had a smaller vertical distance from the inferior border of the pubic symphysis and a smaller posterior vesicourethral angle in the forceps group compared with the cesarean section group.In the forceps group,the angle of urethral inclination was greater,and the area of the anorectal hiatus was smaller in the resting state compared with the natural birth group and cesarean section group.In the Valsalva state,the vertical distance of the bladder neck and the cervix from the lower edge of the pubic symphysis were smaller in the forceps group compared with the natural birth group and cesarean section group.In the transition from resting to Valsalva state,the angle of rotation of the urethra was greater in the natural birth group and the forceps group than in the cesarean section group.Cervical mobility and recto-pubic abdominal mobility were greater in the forceps group compared to the natural birth group and the cesarean section group.All these differences were statistically significant(P<0.05).Conclusion In the early stage of labor,forceps-assisted delivery had a greater effect on the displacement of pelvic floor organs than natural labour and cesarean section.
