What is HSG and when is it done?
Hysterosalpingography (HSG) is a method of examining the patency of the fallopian tubes. In order for pregnancy to occur, the fallopian tubes must be preserved.
HSG is a diagnostic - therapeutic procedure performed to examine fertility in women and assess the existence of abnormalities in the structure of the uterus.
In this imaging, an iodine-based contrast agent is used, and the imaging is done with an X-ray machine in order to show the inside of the uterine cavity and fallopian tubes.
Timing is important for this method, because HSG is done only two or three days after the end of menstrual bleeding (on the ninth or tenth day of the first day of menstruation) to avoid the entry of contrast into blood vessels.
How long does the HSG procedure take and what does the procedure itself look like?
The procedure takes 10 minutes, and with the entire preparation about 15 minutes.
It is performed by placing an instrument on the cervix, through which contrast is injected. This contrast fills the cervical canal, enters the fallopian tubes and if their openings are transient, passes into the abdominal cavity. Contrast is observed by X-ray.
During the performance, X-rays are made that show in detail the condition of the cervix, uterine cavity and fallopian tubes, their anatomy and patency. Developmental anomalies of the uterus may be shown. With less pronounced adhesions on the fallopian tubes, the effect of improving and establishing the patency of the fallopian tubes is achieved.
Is the procedure painful?
The procedure is not painful, it is short and three radiological images are taken during it. The results will be completed immediately. After the given procedure, the patient goes home immediately and there is no need for hospitalization.
HSG results are over, what should I do next?
If the fallopian tubes are passable, couples planning a pregnancy try to achieve the same in the next 6 months, because HSG can have a therapeutic effect.
- If after HSG pathological changes within the uterus, polyps, fibroids and complete or partial septa are found, then these problems are solved hysteroscopically through the cervical canal. If the canals are filled, and the contrast does not pass into the abdominal cavity, then it is necessary to do a laparoscopy. If it is determined that the fallopian tubes are impassable, it is necessary to make a decision on further treatment, which is individual for each patient.
