Clinical Values Of Three-Dimensional Ultrasound In The Diagnosis Of Uterine Diseases And Intrauterine Device Dislocation

Objective: To evaluate the diagnostic value of three-dimensional ultrasonography(3D-US) for uterine diseases and intrauterine device(IUD) dislocation.Methods: A total of 110 patients with suspected uterine diseases or IUD dislocation (60 uterine intracavitary lesions, 19 congenital uterine anomalies, 31 IUD dislocation) were examined by 3D-US and 2D-US, and the findings of ultrasound were compared with the hysteroscopic or surgery-pathologic results, and analyzed to assess sensitivity and accuracy of 3D-US and 2D-US.Results:1.Compared with the pathological findings, the diagnostic sensitivity, specificity and accuracy of 2D-US and 3D-US for uterine intracavitary lesions were 94.7%, 81.8%, 76.7% vs 97.4%, 90.9%, 91.7%,respectively. The diagnostic accuracy of 3D-US was significantly higher than that of 2D-US(P<0.05).2.The diagnostic sensitivity, accuracy of 3D-US (100%, 100%) for congenital uterine anomalies was higher than that of 2D-US (78.9%, 57.9%).3.Although the sensitivity and accuracy of 3D-US for IUD dislocation (96.2%, 96.8%) were higher than that of 2D-US (76.9%, 977.4%), the difference between two methods was not significant (P>0.05).Conclusions: Three-dimensional ultraound allows improved visualization of the uterine cavity by allowing rapid orthogonal imaging in the sagital, axial and coronal plane. Our study suggested that it is a simple, effective, and non-invasive method with high sensitivity and accuracy for detecting uterine intracavitary lesions, uterine anomalies and intrauterine device dislocations, and its use is helpful in the selection of appropriate management and surgical procedure.
