Abstract: Objective：To evaluate the tubal mucosal status using hysteroscopy as a succedaneum of salpingoscopy in those patients with hydrosalpinx. Methods：A total of 64 infertility patients who underwent laparoscopic tubal anaplasty due to unilateral or bilateral tubal hydrosalpinx were recruited between January 2013 to December 2015. Hysteroscopy was used as a succedaneum of salpingoscopy to evaluate the mucosa of the tubal ampulla, while the r-AFS staging system was also used. The patients were followed up for 6 to 42 months after surgery. Four cases were lost in follow-up. Results：Among the 60 patients, 18 cases got natural intrauterine pregnancy. Among them, 16 cases were classified as grade Ⅰ, with the pregnancy rate 66.7% (16/24); 2 cases were classified as grade Ⅱ, with the pregnancy rate 12.5% (2/16). There was a significant difference in the rate of natural intrauterine pregnancy between the grade Ⅰgroup and  the grade Ⅱgroup (P=0.003). There were 8, 4 and 6 patients who got their natural intrauterine pregnancy in the r-AFS′s grade Ⅰ, Ⅱ and Ⅲ group, respectively. There is no correlation between the rate of natural intrauterine pregnancy and the r-AFS′s score ( χ2=1.905, P=0.442). Conclusions：There is a significant correlation between the score evaluated by hysteroscopy as a succedaneum of salpingoscopy with the pregnancy outcome, suggesting that this is a alternative clinical method.
