ABSTRACT

Objective To evaluate the feasibility and accuracy of the transvaginal real-time three-dimensional hysterosalpingo-contrast sonography(RT 3D-HyCoSy) with SonoVue in the assessment of tubal patency.Methods Tubal patency was investigated by RT 3D-HyCoSy in 96 unselected infertile patients (a total of 191 tubes).The image quality of RT 3D-HyCoSy was evaluated.Laparoscopy was performed in 35 cases (a total of 70 tubes) of them.The efficacy of the procedure was compared with laparoscopy.Results The mean score of image quality of RT 3D-HyCoSy in ninety-six cases was 2.94 ± 0.26.The accordance between RT 3D-HyCoSy and laparoscopy was good,with the Kappa value was 0.802.Sensitivity,specificity,positive predictive value,negative predictive value and accuracy in diagnosing tubal patency by using RT 3D-HyCoSywas 87.5％ (14/16),94.4％ (51/54),82.3％ (14/17),96.2％ (51/53),92.9％ (65/70),respectively.Conclusions Transvaginal RT 3D-HyCoSy is a good imaging technique which can display the morphological character of fallopian tube and assess the patency.
