2. Physical examination;

3. Transvaginal ultrasound examination: Beaded or sausage-shaped anechoic areas in pelvic cavity can be seen under B-ultrasound, and separation can be seen inside;

4, salpingography: can make a clear diagnosis, and can make clear the patency of fallopian tubes;

5. Laparoscopy: It can be used for both examination and treatment. Laparoscopic examination can determine the degree of hydrosalpinx and tubal adhesion to surrounding tissues, and judge whether there are pelvic effusion, pelvic adhesion, endometriosis and polycystic ovary. Laparoscopic tubal plastic surgery, proximal tubal ligation, distal salpingostomy and salpingectomy can be performed. However, laparoscopic surgery is expensive and requires general anesthesia, so it is not the first choice.
