Abstract To explore the effect of the tubal patency evaluated by transvaginal dynamic three-dimensional hysterosalpingography ultrasound (RT 3D-HyCoSy), and to study the related influence factors. Methods: 80 infertility women with 152 fallopian tubes were examined by RT 3D-HyCoSy from March 2018 to March 2020. The imaging characteristics of the patency of these fallopian tubes were observed and evaluated. The result of the laparoscopic examination of meilantong passed was regarded as the "gold standard". The diagnostic effect of RT 3D-HycoSY was observed based on the uterine position of the women, whether or not of the contrast agent refluxed in muscular layer, and whether or not of adnexal mass. Results: Compared with those of the gold standard, the sensitivity, the specificity, and the diagnostic coincidence rate of RT 3D-HyCOSY for diagnosing 154 fallopian tubes were 83.3%, 90.6%, and 88.3%, respectively. The coincidence rate of diagnosing pre-uterine/post-uterine position was significantly higher than that of diagnosing mid-uterine position. The coincidence rate of diagnosing no contrast agent refluxed in muscular layer was significantly higher than that of diagnosing contrast agent refluxed in muscular layer. The coincidence rate of diagnosing no mass in adnexa uteri was significantly higher than that of diagnosing mass in adnexa uteri (P＜0.05). Conclusion: RT 3D-HyCoSy for evaluating fallopian tube patency has higher accuracy. The position of the uterus, myometrial reflux of contrast agent, and mass in adnexa uteri can all affect the diagnostic coincidence rate of RT 3D-HyCoSy.
