To explore the effect of Yishen Huayu Recipe（益肾化瘀方）combined with bioelectric stimulation on preventing recurrence after hysteroscopic intrauterine adhesion separation.

A total of 148 patients with severe intrauterine adhesions（admitted from June 2020 to June 2023）were included in the study and divided into observation group and control group by random number table method，with 74 cases in each group. The patients in the control group were treated with hysteroscopic intrauterine adhesions separation combined with simulated bioelectric stimulation. Those in the observation group were treated with Yishen Huayu Recipe on the basis of the treatment of patients in the control group. During the treatment，2 cases fell off in the control group and 3 cases fell off in the observation group. The data of each group was observed，including the efficacy，the postoperative complications，the total scores of TCM symptoms and uterine adhesion scores before and after treatment，uterine volume and endometrial thickness，pulse index（PI）and vascular resistance index（RI）before and after treatment，Pictorial Blood Loss Assessment Chart（PBAC）scores before surgery，1 and 2 months after surgery，recurrence rate of uterine adhesion and successful pregnancy rate 6 months after surgery.

The treatment effect of the observation group was better than that of the control group，and the postoperative complication rate was lower than that of the control group（P<0.05）. After treatment，the total scores of TCM symptoms，uterine adhesion score，uterine volume and endometrial thickness，PI and RI were improved in both groups，and the total scores of TCM symptoms，uterine adhesion score，uterine volume and endometrial thickness，PI and RI in the observation group were better than those in the control group（P<0.05）. The PBAC score of the observation group 1 and 2 months after operation was better than that of the control group（P<0.05）. The recurrence rate of intrauterine adhesions in the observation group was lower than that in the control group 6 months after operation，and the successful pregnancy rate was higher than that in the control group（P<0.05）.

Yishen Huayu Recipe combined with bioelectric stimulation can better improve the surgical effect of hysteroscopic intrauterine adhesion separation，prevent the recurrence of intrauterine adhesion，improve the clinical symptoms and uterine conditions of the patients，reduce the postoperative complications and increase the successful pregnancy rate，which is worthy of application.
