How to do fallopian tube dredging

There are two methods of tubal dredging, the specific operation methods are as follows, 1, if the choice of tubal fluid is to inject a certain amount of liquid into the fallopian tube, through the resistance of the liquid to determine whether there are symptoms of blockage. 2, the second method is to carry out salpingography, salpingography is a more common method, clinical use is more extensive. This test involves injecting a contrast medium into the fallopian tube, and then examining it on a radiograph to determine the location of the blockage. Both methods can determine whether there is a fallopian tube blockage, and treatment can be further developed after salpingography.
