Evaluation of the fallopian tube patency with transvaginal three-dimensional hysterosalpingo-contrast sonography

Objective To assess the feasibility and accuracy of the transvaginal three-dimensional hysterosalpingo-contrast sonography(3D HyCoSy) on the fallopian tube patency. Methods 3D HyCoSy was performed in twenty-two cases with infertility. Image quality of 3D HyCoSy was evaluated. The estimate of the fallopian tube patency in 3D HyCoSy were compared with those of hysterosalpinography(HSG) in one week. Results The mean score of image quality of 3D HyCoSy in twenty-two cases was 2. 8 + 0. 5. The accuracy of the unobstructed and obstructed fallopian tube were 88.9% (24/27) and 94.1% (16/17) respectively, and the total accuracy was 90. 9% (40/44) , which was equal to the results of HSG (P = 0. 000,k = 0. 812). No adverse reactions of SonoVue occurred in the cases. Conclusions Transvaginal 3D HyCoSy which is a new imaging technique can safely and effectively display the morphological character of fallopian tube and assess the patency.
