Objective: This study aims to determine the difference between transcervical resection of septum (TCRS) and transcervical incision of septum (TCIS) in the improvement of reproductive prognosis. Study Design: Women with uterine septum in the Affiliated Hospital of Ningxia Medical University were retrospectively analyzed. A statistical method was used according to operative time, postoperative menstruation, postoperative pregnancy rate, postoperative term delivery rate, and so on. Results: Compared with TCRS, the TCIS method decreased operative time, blood loss, and consumption of uterus distension medium. No statistical difference was observed in operative complications between the two methods. After TCIS, the incidence of uterine adhesion was low and the degree of endometrial epithelialisation was high by hysteroscopy review. No statistical difference was observed in residual septum after the operation. The total pregnancy rate after TCIS was higher than that of TCRS. However, no statistical difference was observed in early and late pregnancy loss rates, preterm birth rate, and term birth rate. Conclusion: TCIS exhibits advantages of decreasing operative time, blood loss, and consumption of uterus distension medium. TCIS can reduce the incidence of uterine adhesion and can promote endometrial epithelialisation, which are the key factors to increase pregnancy rate after operation.
