Abstract: Objective: To explore the probability of hysteroscopy, replacing salpingoscopy, in tubal reconstructive surgery with infertility of hydrosalpinx. Methods: Data from 43 patients with infertility of hydrosalpinx who accepted operation in our hospital from January 2012 to August 2012 were retrospectively analyzed. All the patients received the conjunction of hysteroscopy with laparoscopy. Under hysteroscopy, we observed the tubal lumen, including adhesions, loss of mucosal folds, rounded edges of mucosal folds, debris, foreign bodies and abnormal vessels. The F score expressed the sum of the above abnormal results, each abnormal result was given one score. After linear salpingectomy or salpingostomy following the F score, a follow-up within 24 months was done, and the pregnancy rate and the live birth rate were recorded. Results: In 43 patients, 66 tubes were diagnosed as hydrosalpinx by laparoscopy, 8 tubes (F score≥2) were removed. The pregnancy rate was 45%（18/40）, and the live birth rate was 35%（14/40）. Conclusions: Hysteroscopy can be used to replace salpingoscopy to observe the tubal lumen, which can afford beneficial suggestion of hydrosalpinx therapy.
