Objective: To development a method for the evaluation of tubal patency with trans vaginal ultrasonography(TVC). Method: Scanning the pelvicwith TVC; to compare with Hysterosalpingography(HSG) by two methods: intrauter hydrotubation, and belly saline fill-in. Results: With the method for the evaluation of tubal patency with TVC, tubals were diagnosed as going-through fluently, going-through influently, obstruction, Compared with HSG, there was not obviously defference between the evaluation of tubal patency at statistics (P>0.05). Compared with HSG,there was obviously defference between the evaluation of tubal patency at statistics (P>0.05), fimbriae of oviduct were diagnosed as adhesion; Conclusions: Salpingosonography is a primary way and it is simple and easy to conduct in the diagnosis of infertility.
