A comparative study was designed to determine whether three-dimensional transvaginal sonography (3D-TVS) offered advantages over two-dimensional transvaginal sonography (2D-TVS) for the identification and location of IUDs in 66 asymptomatic women. Hysteroscopy was performed in cases in which there was a discrepancy between the information obtained by both methods (n = 14). In eight cases (12.2%) the IUD was misidentified with 2D-TVS. In six cases (9.1%) it was not possible to identify the device model with 2D-TVS. In two cases (3.0%) 2D-TVS failed to identify the position of the device. In contrast, all IUDs were identified and located accurately with 3D-TVS.
一项比较研究旨在确定三维经阴道超声检查（3D-TVS）在识别和定位66名无症状女性子宫内节育器（IUD）方面是否比二维经阴道超声检查（2D-TVS）更具优势。对于两种方法获取的信息存在差异的病例（n = 14），进行了宫腔镜检查。在8例病例（12.2%）中，2D-TVS误识别了IUD。在6例病例（9.1%）中，2D-TVS无法识别节育器型号。在2例病例（3.0%）中，2D-TVS未能识别节育器的位置。相比之下，所有IUD均通过3D-TVS准确识别和定位。
