The difference between hysteroscopy and tubalography is as follows: 1, tubalography is injected into the uterine cavity, the contrast agent along the fallopian tube, from the umbilical end of the fallopian tube out, and the contrast agent in the fallopian tube will leave an image of the fallopian tube, according to the clinic to take the image, to confirm that the fallopian tube whether the tubes are clear or not; 2, hysteroscopy can be observed inside the uterine cavity, but the hysteroscopy can only be observed on both sides of the opening of the fallopian tubes, but can not observe the tubal tube whether the tubal tubes are clear or inside the tubal tubes; In addition, the hysteroscopy is different from the laparoscopy, laparoscopy is used for the observation of the appearance of the uterus in the shape of the laparoscopy.
