Tubal imaging legs are not fixed and have no effect. Tubography is a test method for female infertility in order to understand the size and shape of the uterus, whether the fallopian tubes are smooth, the direction of the fallopian tubes, and whether the umbilical hydrocephalus occurs; it needs to be carried out in the case of a woman who has cleaned up her menstruation for 3-7 days to avoid having sex and exclude the case of acute infections of the reproductive organs. Without anesthesia, the patient is required to take the truncated position, legs apart, flexed, fully exposed vulva, injected into the uterine cavity with a certain dose of contrast medium, and the uterus and fallopian tubes are observed under the X-ray film. During the process of injecting the contrast medium, the patient will experience some pain. If the tubal obstruction is serious, the pain is often severe and needs to be relieved by hysterolaparoscopic surgery when a clear diagnosis is made. If the desired results are not achieved after surgery, pregnancy can only be obtained through IVF.
