Value of Transvaginal 3D Ultrasound in Diagnosing Abnormal Position of Intrauterine Device
Objective To investigate the value of transvaginal 3D ultrasound in diagnosing abnormal position of intrauterine device(IUD).Methods A total of 98 suspected cases with abnormal position of IUD in Zhengzhou Central Hospital Affiliated to Zhengzhou University from May 2020 to April 2021 were selected and underwent both transvaginal 2D and 3D ultrasound examinations.With hysteroscopy results as the"gold standard",the diagnostic results and diagnostic efficacy of transvaginal 2D and 3D ultrasound were statistically analyzed.The positive predictive value and negative predictive value were analyzed,and the detection rate of different types of abnormal position of IUD by transvaginal 2D and 3D ultrasound was compared.Results Among the 98 suspected cases with abnormal position of IUD,74 cases were diagnosed positive and 24 were diagnosed negative by hysteroscopy.Transvaginal 2D ultrasound diagnosed 56 positive cases and 16 negative cases,while transvaginal 3D ultrasound diagnosed 71 positive cases and 23 negative cases.The diagnostic sensitivity,specificity,and accuracy of transvaginal 3D ultrasound were 95.95％(71/74),95.83％(23/24),and 95.92％(94/98),respectively,which were higher than those of transvaginal 2D ultrasound[75.68％(56/74),66.67％(16/24),73.47％(72/98)].The missed diagnosis rate[4.05％(3/74)]and misdiagnosis rate[4.17％(1/24)]were lower than those of transvaginal 2D ultrasound diagnosis[24.32％(18/74),33.33％(8/24)](P＜0.05).The positive predictive value and negative predictive value of transvaginal 3D ultrasound[98.61％(71/72),88.46％(23/26)]were also higher than those of transvaginal 2D ultrasound[87.50％(56/64),47.06％(16/34)](P＜0.05).The detection rate of transvaginal 3D ultrasound for different types of abnormal position of IUD was 95.95％(71/74),which was higher than that of transvaginal 2D ultrasound[75.68％(56/74)](P＜0.05).Conclusion Transvaginal 3D ultrasound can improve the diagnostic sensitivity,specificity,and accuracy of abnormal position of IUD,reduce the incidence of missed diagnosis and misdiagnosis,and determine the type of abnormal position,providing a reference for targeted clinical treatment.
