Abstract
Objective To explore the application of real-time three-dimensional ultrasound in evaluating postpartum bladder neck dis-placement and pelvic diaphragm hiatus structural changes in women following different delivery methods,aiming to provide a refer-ence for postpartum pelvic floor function recovery.Methods A retrospective analysis was conducted on the clinical data of 140 post-partum women admitted to our hospital between February 2022 and January 2023.Based on delivery methods,the participants were assigned to a cesarean section group(65 cases)and a vaginal delivery group(75 cases).All participants underwent pelvic floor three-dimensional ultrasound at 6 weeks postpartum to measure bladder detrusor muscle thickness and bladder neck mobility during the Valsalva maneuver.Real-time observations were made of the anterior-posterior diameter,left-right diameter,and area of the pelvic diaphragm hiatus in resting,Valsalva,and anal contraction states.Rehabilitation therapy commenced at 6 weeks postpartum,with a follow-up pelvic floor three-dimensional ultrasound performed at 12 weeks postpartum to record and compare changes in blad-der detrusor muscle thickness,bladder neck mobility,and pelvic diaphragm hiatus parameters as well as anterior-posterior diameter,left-right diameter,and area of the pelvic diaphragm hiatus in resting,Valsalva,and anal contraction states between the two groups at 6 and 12 weeks postpartum.Results At 6 weeks postpartum,the cesarean section group exhibited significantly lower bladder de-trusor muscle thickness and bladder neck mobility compared to the vaginal delivery group;the anterior-posterior diameter,left-right diameter,and area of the pelvic diaphragm hiatus in resting,Valsalva,and anal contraction states were also significantly smaller in the cesarean section group(P<0.05).At 12 weeks postpartum of recovery,both groups showed reduced bladder detrusor muscle thickness,bladder neck mobility,and pelvic diaphragm hiatus parameters in resting,Valsalva,and anal contraction states compared to 6 weeks postpartum of recovery(P<0.05).However,no significant differences were observed between the two groups at 12 weeks postpartum regarding bladder neck displacement and pelvic diaphragm hiatus structural parameters(P>0.05).Conclusion Both cesarean section and vaginal delivery can lead to postpartum pelvic floor dysfunction,with vaginal delivery having a more signif-icant impact.Active rehabilitation therapy contributes to postpartum pelvic floor function recovery.Real-time three-dimensional ul-trasound can accurately reflect pelvic floor structural changes and is of considerable guiding value for postpartum pelvic floor function recovery.关键词
