Abstract
Objective To access the diagnostic accuracy and clinical value of transvaginal real time three-dimensional hysterosalpingo-contrast sonography (RT-3D-HyCoSy) in evaluating the fallopian tube patency.Methods 428 infertile women were under went transvaginal RT-3D-HyCoSy and 32 of them were underwent laparoscopically salpingoraphy to evaluate the fallopian tube patency.Results 846 fallopian tubeswere studied by RT-3D-HyCoSy,271 of them were unobstructed,202 of them were obstructed,373 of them were partially passable.Compared with laparoscopically salpingography,sensitivity,specificity,positive predictive value and negative predictive value of transvaginal RT-3D HyCoSy were 84.0％,100％,87.5％ and 90.9％,respectively.The transvagianl RT-3D HyCoSy and the laparoscopy with a Cohen's Kappa was 0.788.Conclusions Transvagianl RT-3D HyCoSy could dynamic show the visualization of the course from uterus to distal tubal and the both ovary consecutively.It has more advantage in assessing the patency of tubal and distal tubal function.
