The Clinical Research Of The Combination Of Transvaginal Two-dimensional Ultrasound And Transvaginal Three-dimensional Ultrasound In The Diagnosis Of Intrauterine Adhesions

Objective: To explore the clinical value of the combination of transvaginaltwo-dimensional ultrasound (2D-TVS) and transvaginal three-dimensionalultrasound（3D-TVS）in the diagnosis of intrauterine adhesions(IUA).Mtheods:84femal with suspicious of intrauterine adhesions wereexamined separately by transvaginal two-dimensional ultrasound（2D-TVS）,transvaginal three-dimensional ultrasound （3D-TVS）and the combination of2D-TVS and3D-TVS. The results of hysteroscopy (HS) were considered asstandard.Compare the detectablerates of the three methods in the diagnosis ofIUA.Results: The sensitivity,specificity,Youden index of2D-TVS and3D-TVSwere72.4%、62.5%、0.35and81.2%、87.6%、0.69; the accordance rates betweenthem and HS were71.4%and82.1%, and the difference of detectablerate had no statistical significance（P＞0.05）.The sensitivity，specificity，Youden index ofthe combination of2D-TVS and3D-TVS were94.7%、75.0%、0.70, theaccordance rate between it and HS was95.2%,and the differences ofdetectablerates between it and the other two methods before both had statisticalsignificance（P＜0.05）.Conclusion：The combination of2D-TVS and3D-TVS is convenient,efficacious and non-invasive.It can be used as the first choice method for thediagnosis of IUA. The clinical value of2D-TVS in the diagnosis of IUA is notobviously inferior to3D-TVS and can be used as a routine screening method.
