Observation on the change of positions and movements of postpartum female pelvic organs under different delivery ways by perineum ultrasound

Objective To observe the changes of positions and movements of female pelvic organs after delivery under different delivery ways by perineum ultrasound.Methods A total of 100 primiparas who gave birth after 6-8 weeks in our hospital from January of 2015 to July of 2016 were recruited. According to the delivery way, 52 cases were divided into vaginal delivery group and 48 cases was divided in elective cesarean section group. And 50 women who never pregnant were as contrast group. The changes of pelvic organ positions and movements at the statement of rest and Valsalva maneuver in different groups were observed. The parameters were compared and analyzed.Results ① At the statement of rest and Valsalva maneuver, the UVJ-VD、CV-VD of vaginal delivery group were lower than those of cesarean section group. The difference between the two groups was statistically significant (P<0.05). At the statement of rest and Valsalva maneuver, The UVJ-VD, CV-VD and ARJ-VD in vaginal delivery group and the cesarean section group were lower than those in the control group. The difference between the two groups was statistically significant (P<0.05).② The degree of movement of UVJ, CV and ARJ in the vaginal delivery group and cesarean section group were all greater than those in the control group. The difference was statistically significant (P<0.05). ③The rates of anterior, middle and posterior pelvic prolapse in vaginal delivery group and the cesarean section group were all higher than those in the control group. The difference was statistically significant (P<0.05). The rate of anterior pelvic prolapse in vaginal delivery group was higher than that in the cesarean section group. The difference between the two groups was statistically significant (P<0.05). The rates of middle and posterior pelvic prolapse in vaginal delivery group were slight higher than those in the cesarean section group. However, there were no significant difference between the two groups (P> 0.05).Conclusion Different delivery ways have different impacts on the positons and movements of female pelvic organs.
