Abstract: In this paper, the abdominal ultrasound testing and its guidance on the timing of uterine curettage for patients with intrauterine residue after medical abortion were investigated. 164 cases of patients with intrauterine residue after medical abortion enrolled in the department of gynecology of our hospital from April 2017 to October 2018 were selected as research objects. All patients received abdominal ultrasound testing, the abnormal intrauterine echogenic mass, intrauterine blood flow signal and spectrum were observed, the treatment and pathological results were recorded. Patients were divided into successful group and the outcome group, and the influencing factors of conservative treatment failed to uterine curettage were analysed by multi-factor logistic regression. Results showed that, among the 164 cases of patients, 79(48.17%) cases were detected with nourish blood flow by ultrasonography, 47(59.49%) cases received uterine curettage, and 32(40.51%) received curettage treatment when the conservative treatment failed. 85(51.83%) cases were detected without nourish blood flow by ultrasonography, 73(85.88%) cases received conservative treatment, and 12 (14.12%) received curettage treatment after conservative treatment failed. There were statistically significant differences on vaginal bleeding time, duration of vaginal bleeding, number of miscarriages, intrauterine residue, and detection rate of nourish blood flow in presentation successful group (n=73) and the outcome group (n=44) (P<0.05). Multi-factor logistic regression analysis showed that vaginal bleeding time, number of miscarriages, intrauterine residue, and ultrasonography detected with nourish blood flow were the independent influencing factors of conservative treatment failed to uterine curettage (P<0.05). This study confirms that abdominal ultrasonography shows the presence of nourish blood flow signal in abnormal echogenic mass can be used as a surgical indication for uterine curettage of patients with intrauterine residue after medical abortion, it is beneficial to improve the prognosis of patients.
