To compare the therapeutic effect of high-intensity focused ultrasound with uterine curettage and uterine artery embolization with uterine curettage in cesarean scar pregnancies.

A retrospective analysis was conducted in 60 patients with cesarean section scars, who admitted to the Department of Obstetrics and Gynecology, the Third Affiliated Hospital of Guangzhou Medical University from January 2014 to January 2019. The patients were divided into observation group (high-intensity ultrasound with uterine curettage) and control group (uterine artery embolization with uterine curettage); 30 cases in each group. T test or Chi-square tests were performed for test statistical analysis.

The length of hospital stay in the observation group was (6.87±2.64) days, which was lower than that of the control group (10±4.79) days, Z=2.21, P<0.05. The hospitalization expenses of the observation group (15 524.47±8035.73) was less than that of the control group (25 390.80±12 914.10) yuan, t=2.51, P<0.05. The menstrual recovery time in the observation group was (35.93±4.00) days, less than that of the control group (40.90±6.63) days, t=2.50, P<0.05. The incidence rate of postoperative pain in the observation group was 6.6%, which was lower than 40% in the control group, χ²=8.91, P<0.05. There were no significant differences in the amount of intraoperative vaginal bleeding, duration of postoperative vaginal bleeding, decline time of human chorionic gonadotropin in blood after operation, gastrointestinal reactions, postoperative fever and pelvic infection between the two groups (P>0.05).

High-intensity focused ultrasound with uterine curettage shorten hospitalization time, lower hospitalization costs, decrease recovery time of menstruation after surgery and reduced the incidence of post-operative pain in the patients with cesarean scar pregnancy.
