The difference between hydrotubation and angiography is huge

Hysterosalpingography is mainly formed by X-ray irradiation and adopts high-end technology. Apart from a little pain, it has no side effects. However, hydrotubation uses only ordinary saline solution and is completely based on the doctor's subjective judgment. The requirements for doctors are relatively high. Therefore, there is still a difference between the two. So what is the difference between hydrotubation and hysterosalpingography?

First, check accuracy

Hysterosalpingography is a procedure in which contrast agents are injected into the female uterine cavity and fallopian tubes using a catheter, and then X-rays are used to form images. The appearance of the contrast agents in the fallopian tubes and pelvic cavity is used to determine whether the fallopian tubes are unobstructed, the location of the blockage, and the morphology of the uterine cavity. In short, high-end technology can be used to visually see the internal conditions of the fallopian tubes and uterine cavity. Hydrotubation is the process of injecting methylene blue solution or normal saline into the uterine cavity from the cervix, and then flowing it into the fallopian tube from the uterine cavity. The resistance during injection and the reflux of the liquid are used to determine whether the fallopian tube is unobstructed. The size of the resistance is determined entirely by the doctor's personal feeling and experience, which places high demands on the doctor and has a relatively low accuracy rate.

Second, therapeutic

During hysterosalpingography, the injected contrast agent has a mechanical effect of flushing the fallopian tubes. The pulling effect on the cervix during hysterosalpingography may sever some mild adhesions around the fallopian tubes. In other words, hysterosalpingography has the effect of clearing mildly adhered and blocked fallopian tubes. The fallopian tube hydrotubation is not available.

Third, side effects

Hysterosalpingography has therapeutic effects, so what are the side effects? The only thing that can be described is probably “pain”. At the same time, if you choose iodine oil contrast, because the iodine oil contrast agent has a certain stimulating effect on the fallopian tubes, it will cause contraction and the discomfort will be more obvious. This will not happen with iodine water contrast! The pain of hydrotubation is more obvious, and if the doctor's skills are not strong enough, it can easily cause damage to the fallopian tube.
