Salpingography with a needle

Salpingography is a general term for a test to see if the fallopian tubes are open. In fact, the use of drugs to understand whether the fallopian tube patency. The ones that we use now that are relatively safe and relatively non-invasive are two. One is contrast-enhanced ultrasound, which is a special contrast agent that you can use to put a contrast agent into the fallopian tube to show how the fallopian tube is going and what it looks like; You can do the same thing with X-rays; And one of them just laparoscopically opens the belly to see what's going on with the fallopian tubes. This last one is invasive, because it's done by going into the abdominal cavity, so it's invasive, and the first two are not invasive. But people prefer CEUS because there are no X-rays and there is no harm to the fetus, to future pregnancies or to the human body.
