Abstract: Objective：To investigate the factors affecting pregnancy rate in patients with fallopian tube obstruction after selective salpingography (SSG) and fallopian tube recanalization. Methods：A retrospective study was conducted for 75 women who underwent SSG in the Department of Obstetrics and Gynecology, International Peace Maternal and Child Health Hospital, Shanghai Jiao Tong University School of Medicine. Logistic regression analysis was used to evaluate the influence factors of postoperative pregnancy rate in patients. Results：Technical success rate of all patients underwent SSG was 82.67%. Within one year after SSG and recanalization, 46.7% of women had conceived. Multivariable analysis showed that the infertility type (OR=3.02, 95%CI 1.32-3.78, P<0.05), duration of infertility<3 years (OR=5.11, 95%CI 1.61-7.35, P<0.05), and age<35 years (OR=3.43, 95%CI 1.87-6.64, P<0.05) were significantly associated with repregnancy rate. Conclusions：Factors including the infertility type, duration of infertility, and age might be associated with the pregnancy after fallopian tube recanalization in patients with fallopian tube obstruction, patients with secondary infertility, duration of infertility<3 years, and age<35 years might have higher pregnancy rate.
