Uterine adhesions can be detected basically by ultrasound, but also by hysterosalpingography and hysteroscopic surgery. 1. Ultrasound: Vaginal ultrasound can indicate partial or complete occlusion of the uterine cavity, but mild uterine adhesion ultrasound examination has a certain chance of missing the diagnosis. 2. Hysterosalpingography: By injecting a contrast medium into the uterine cavity, the shape and size of the uterine cavity can be visualized, showing whether there are adhesions and occlusions. Mild adhesions can be relieved in this way. 3. Hysteroscopic Surgery: Through hysteroscopic surgery, the morphology of the uterine cavity and the degree of adhesion can be judged visually, and endometrial lesions can be detected, and at the same time, adhesions can be loosened and endometrial lesions can be excised, so as to achieve the purpose of diagnosis and treatment.
