三维盆底超声联合临床盆底功能检测评估会阴侧切对足月初产妇近期盆底的影响OA

Objective:To comprehensively evaluate the impact of episiotomy on short-term pelvic floor function in primi-parous women after full-term delivery using three-dimensional pelvic floor ultrasound combined with clinical pelvic floor as-sessment.Methods:A retrospective study was conducted on 60 primiparous women who delivered vaginally at Nanning First People's Hospital between June 2024 and April 2025.Participants were divided into two groups:the study group(with epi-siotomy,n=30)and the control group(without episiotomy,n=30).All subjects underwent 3D pelvic floor ultrasound,pelvic mus-cle strength and pressure assessment,and POP-Q staging at 42～60 days postpartum.Differences in various indicators between the two groups were compared.Results:No significant differences were observed between the two groups in general character-istics,pelvic muscle strength,dynamic pressure,most POP-Q parameters,or ultrasound measurements(P>0.05).However,the total vaginal length(TVL)in the study group was significantly longer than that in the control group(P=0.026).Additionally,the position of the uterine cervix during maximum Valsalva was significantly lower in the study group(P=0.025 5),and the inci-dence of uterine prolapse in the study group was significantly higher than that in the control group(P=0.032).Conclusion:Episiotomy can not significantly improve short-term pelvic floor function and may be associated with an increased risk of u-terine prolapse,indicating its limited protective effect on the pelvic floor.Therefore,episiotomy should be strictly controlled and not be used as a routine procedure in vaginal delivery.
