ABSTRACT
Purpose To investigate the clinical value of three-dimensional hysterosalpingo-contrast-sonography (3D-HyCoSy) in the assessment of fallopian tubal patency.Materials and Methods Fallopian tubal patency of 33 infertile women was assessed using transvaginal 3D-HyCoSy, and the results were compared with laparoscopically salpingoraphy, the sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of 3D-HyCoSy were evaluated.Results 3D-HyCoSy showed 20 passable fallopian tubes, 10 partially passable fallopian tubes and 36 obstructed tubes, while lapascopically salpingoraphy showed 23 passable fallopian tubes, 7 partially passable fallopian tubes and 36 obstructed tubes. The total coincidence rate of 3D-HyCoSy to assess the fallopian tubal patency was 86.4% (57/66), with the sensitivity of 93.0% (40/43), specificityof 73.9% (17/23), positive likelihood ratio of 7.15, and negative likelihood ratio of 0.20.Conclusion Tubal patency can be efficiently and accurately assessed using 3D-HyCoSy, but patients with obstructed or partially passable fallopian tubes should undergo laparoscopy to clarify.
