Comparative Study of Transvaginal Two-dimensional and Three-dimensional Ultrasound in Diagnosis of Congenital Uterine Anomalies

Objective To compare the efficiency of transvaginal three-dimensional(3D) and two-dimensional(2D) ultrasound in diagnosis of congenital uterine anomalies.Methods From July,2007 to December,2011,sonographic data of 152 cases diagnosed of congenital uterine anomalies by transvaginal 2D or 3D ultrasound were analyzed retrospectively.The results of these two methods were compared using hysterosalpingogaphy combined with hysteroscopy/celioscopy as gold standard.Results Diagnosis of 3D/2D ultrasound were:infantile uterus(3/3).unicornuate uterus(1/3).rudimentary horn of uterus(2/2).bicornuate uterus(12/12),uterus arcuatus(24/19).uterus septus(101/93),didelphia(7/7).normal uterus(2/13).Diagnose accordance rate of 3D and 2D ultrasound were 100% and 90.1% respectively(P=0.000).Conclusion Transvaginal 2D US is foundational examination for congenital uterine anomalies,bur missed diagnosis and misdiagnosis occur sometimes.Transvaginal 3D US can provide accurate diagnostic information for congenital uterine anomalies and improve the diagnostic accordance rate.
