Abstract:

Objective The aim of this study was toinvestigate the diagnostic value of four⁃dimensional hysterosalpingo⁃contrast sonography（4D⁃HyCoSy）combined with saline infusion sonography（SIS）for uterine cavity lesions in infertile women. Methods The clinical data of 244 infertile women detected by transvaginal 4D⁃HyCoSy were analyzed. All the patients were performed with SIS guided by ultrasound after 4D ⁃HyCoSy. The sensitivity， specificityand accuracy of HyCoSy and 4D⁃HyCoSy combined SIS for uterine cavity lesions in the diagnosis of uter⁃ ine lesions were compared and analyzed. Results The sensitivity，specificityand accuracy of uterine cavity lesions diagnosed byHyCoSy were 68.8% ，69.2% and 68.8% ，respectively. While those by HyCoSy combined with SIS were 92.2%，84.6% and 91.8%，respectively. The difference in specificity was not statistically significant（P > 0.05）， while the difference in sensitivity and accuracy was statistically significant（P < 0.001）. Conclusions HyCoSy combined with SIS can clearly show uterine cavity lesions，and its diagnosis of small endometrial polyps，endome⁃ trialhyperplasia and intrauterine adhesions are better than HyCoSy alone. HyCoSy combined with SIS canimprove diagnostic accuracy of uterine cavity lesions.
