摘　　要：目的探讨经会阴实时三维超声影像在不同分娩方式中协助诊断妇女盆底功能损害的价值。方法选取进行分娩的134名产妇。按照分娩方式分为自然分娩组和剖宫产组。两组孕产妇均行会阴实时三维超声成像,对比静息时和Valsalva体位下屏气时膀胱颈的移动度、尿道倾斜角、膀胱后角及肛提肌开口面积的差异。结果自然分娩组孕产妇在Valsalva状态下屏气用力时尿道倾斜角、膀胱后角明显大于剖宫产组孕产妇;膀胱颈活动度、肛提肌裂孔横径、肛提肌裂孔及肛提肌裂孔面积均显著大于剖宫产组,且差异有显著性意义。结论经会阴实时三维超声成像检测有利于协助并诊断产妇产后盆底功能异常,为临床治疗提供可靠依据,具有较高的诊断价值。Objective To investigate the efficacy of real-time three-dimensional transperineal ultrasonography in diagnosing pelvic floor dysfunction in women across various delivery modes.Methods A total of 134 pregnant women who delivered were selected for this study.Based on their mode of delivery,participants were categorized into a natural delivery group and a cesarean section group.Real-time three-dimensional perineal ultrasound imaging was conducted in both groups,allowing for a comparative analysis of bladder neck movement,urethral inclination angle,posterior bladder angle,and anal levator opening area between resting and Valsalva maneuver.Results In the natural delivery group,the inclination angle of the urethra and the posterior bladder angle were significantly greater than those observed in the cesarean section group during breath-holding in a Valsalva maneuver.Additionally,movements of the bladder neck,transverse diameter of the anal levator hiatus,and both area and dimensions of the anal levator hiatus were markedly more pronounced compared to those in the cesarean section cohort,with statistically significant differences.Conclusions Real-time three-dimensional perineal ultrasound imaging is instrumental in assisting the diagnosis of postpartum women with abnormal pelvic floor function,providing a reliable foundation for clinical treatment,and demonstrating high diagnostic value.
