Most of the uterine adhesions are diagnosed by hysteroscopy. Most women with uterine adhesions have a history of multiple abortions, curettage, tuberculous peritonitis, etc. Many women may experience less and less menstrual flow or even no menstruation after curettage, or they may have symptoms such as bloating, back pain, or lumbar pain when they have their menstruation, which should alert them to the possibility of cavity adhesions. If the uterine adhesions are heavy, sometimes the endometrium is thin and the continuity is interrupted under the ultrasound. In addition, hysterosalpingography and tubal imaging may show filling defects. 3D reconstruction ultrasound can be done to confirm the diagnosis of uterine adhesions, but the gold standard for the diagnosis of uterine adhesions is still hysteroscopy.
