To accurately determine whether the patient’s fallopian tubes are open or not, mainly through two methods: the first is tubalography, which can be done under X-ray or ultrasound monitoring. It can visualize the contrast agent through the patient’s uterine cavity and fallopian tube into the patient’s pelvic cavity, and it can objectively observe whether the patient’s fallopian tube is open or not. At the same time, it can also observe whether the patient’s tubal alignment is normal, there is no tubal fluid and other abnormalities; secondly, it is mainly through the combined hysterolaparoscopy, usually hysteroscopy for the Mylan fluids, laparoscopy for monitoring. If laparoscopy can observe that the tubes are overflowing with Mylan fluid, it proves that the patient’s tubes are smooth, but it can’t see how smooth the patient’s tubes are, and whether there is any localized narrowing or slight hydrocele, so its accuracy is not as good as that of tubal angiography.
