Uterine cavity adhesion can be examined by hysteroscopy, hysterosalpingography or transvaginal ultrasound. 1. Hysteroscopy: Through direct vision operation under hysteroscopy, it can accurately locate the adhesive tissues, determine the scope and character, judge the situation of the uterine fundus and tubal openings, and clarify the degree of adhesion in the uterine cavity. Then, the adhesions can be separated by surgery in time to restore the original anatomical shape of the uterine cavity and the volume of the uterine cavity as much as possible. 2. Hysterosalpingography: Hysterosalpingography is to inject contrast into the uterine cavity, fallopian tubes and pelvis, and then X-ray fluoroscopy and radiography will be performed to understand the morphology of the uterine cavity, whether the fallopian tubes are smooth and the location of the obstruction. It can understand whether there is any abnormality in the uterus and fallopian tubes of the patient and provide a direct basis for subsequent diagnosis and treatment. 3. Transvaginal ultrasonography: Transvaginal ultrasonography is to put the probe of vaginal ultrasonography into the vagina for examination, so as to understand the condition of the endometrium, bilateral adnexa and pelvis. Transvaginal ultrasound is one of the most effective ways to diagnose uterine adhesions and is a non-invasive test that can identify the location of the adhesions and the severity of the condition. After the diagnosis of uterine adhesions is confirmed, it is important to follow the doctor’s instructions to carry out the examination, do not leave it unchecked, so as to avoid delaying the condition.
