Pelvic Floor Ultrasound Evaluation of the Impact of Delivery Times and Delivery Methods on the Anterior Pelvic Cavity

Abstract

Objective: To evaluate the impact of delivery frequency and delivery method on the anterior pelvic cavity using pelvic floor ultrasound. Method: 200 women who gave birth in our hospital from January 2019 to January 2022 were selected as the research subjects, including 100 first-time vaginal delivery women, 50 second-time vaginal delivery women, and 50 cesarean section women each. The control group consisted of 100 women who underwent a 15 day follow-up examination after the first artificial abortion surgery in our hospital during the same period. The patients were divided into a control group, a first-time delivery group, a second-time delivery group, and a cesarean section group. Observing the changes in the anterior pelvic structure during resting state and maximum Valsalva movement through perineal ultrasound examination. Result: The distance from the bladder neck to the reference line in the resting state was significantly different between the control group, cesarean section group, first vaginal delivery group, and second vaginal delivery group (P<0.05); During the maximum Valsalva maneuver, the detection rate of bladder neck mobility, urethral rotation angle, posterior angle of bladder, and funneling of internal urethral orifice, the second vaginal delivery group, the first vaginal delivery group>the cesarean section group>the control group, and the difference between each group was statistically significant (P<0.05). During the maximum Valsalva maneuver in the first and second vaginal delivery groups, the lowest point of the bladder was located below the reference line, and there was no statistically significant difference between the two groups (P>0.05); During the maximum Valsalva maneuver in the cesarean section group and control group, the lowest point of the bladder was located on the reference line, and there was no statistically significant difference between the two groups (P>0.05); The difference between the vaginal delivery group and the cesarean section and control group was statistically significant (P<0.05). Conclusion: Different birth times and delivery methods have varying degrees of impact on the anterior pelvic cavity of women. Pelvic floor ultrasound can early evaluate these structural changes and provide reliable basis for the screening and diagnosis of pelvic floor dysfunction disease (PFD).
