HSG is one of the most widely used imaging methods in detecting problems in the uterus and fallopian tubes. Based on this, many gynecological diseases in women are detected in time.

1. What is HSG?

Hysterosalpingography (HSG) or full name is a contrast-enhanced hysterosalpingogram. This is an imaging technique that uses X-rays to examine the inside of the fallopian tubes and uterus.
HSG imaging is used to check and diagnose tubal occlusion (which can be partial or total). Besides, the results after the scan also support the detection of abnormalities related to the size and shape of the uterus. All of these factors have the potential to interfere with female fertility such as infertility/infertility.

2. When is it necessary to have an HSG (hysterosalpingogram) ?

Your obstetrician will order an HSG scan when you're having a hard time conceiving or you've had problems with your pregnancy (eg, multiple miscarriages). A contrast-enhanced hysterosalpingogram will then be performed to diagnose the cause of infertility.

Some of the major causes detected by this technique include:
Abnormalities in the structure of the uterus (which can be congenital or genetic). Fallopian tube blockage. Scar tissue in the uterus. Fibroids . Uterine tumor or uterine polyp. In addition, this diagnostic technique can be performed several months after tubal ligation surgery to ensure success.

3. Steps to prepare before taking HSG

Performing a hysterosalpingogram with contrast can be painful in some patients.
Therefore, doctors will prescribe some over-the-counter pain relievers and patients need to take them about 1 hour before the scan. Besides, if the patient is too nervous, doctors will also prescribe a sedative to help them relax more. To prevent infection, antibiotics will also be prescribed before or after the HSG scan.

It's also important to note that this technique uses X-rays with contrast dye – a substance that highlights organs or tissues from staining surrounding substances. This drug will dissolve and release itself from the body through the urine. However, if you are allergic to barium or dyes, you need to tell your doctor first. Finally, metal can interfere with the results of the scan. So, remove all jewelry from your body before performing this procedure. However, the matter of protecting assets in a crowded place like a hospital is quite complicated, so the best advice is to leave these jewelry at home.

4. When is the right time to take HSG?

An HSG scan is usually done a few days to a week after the end of your period. This ensures that the patient is not pregnant and reduces the risk of infection during the procedure.
Some of the following subjects are not assigned to take HSG:
Pregnant. Having a pelvic infection. There is severe uterine bleeding.

5. How does the HSG scan (hysterosalpingogram) take place?

Step 1: First, the patient will be asked to lie on his or her back and place the legs in the same position as the gynecological examination. Next, the doctor will insert an instrument (like a speculum) into the vagina to widen this area, making it easier to see the cervix. Along with that, the cervix will be cleaned. Step 2: Inject a local anesthetic in the cervix. Step 3: The doctor will insert the dye using one of two methods: using a catheter into the cervix or using a plastic tube with the tip of the tube inflated. Step 4: Remove the speculum from the vagina and insert the dye through the catheter. This fluid will drain into the uterus and fallopian tubes. This process can cause pain and cramping. Step 5: Start taking X-rays with specialized equipment. Step 6: During the scan, the patient may be asked to change positions to have different angles. Step 7: When the scan is complete, the doctor will remove the catheter from the vagina. Step 8: The patient will be prescribed appropriate drugs for pain relief and anti-inflammatory, anti-infective after the end of this procedure.

6. Some risks when performing HSG

This hysterosalpingogram technique can cause some side effects such as:
Vaginal bleeding and cramping. Dizziness, dizziness. Discomfort in the lower abdomen... However, in a small number of cases it is possible to cause: Allergic reaction to the dye. Infection of the fallopian tubes/endometrium if not handled well. Uterine trauma (eg, perforation)...
