Hysterosalpingography (HSG)

What does the HSG of the fallopian tubes involve?

The procedure is carried out in the hospital specialized room "Radiography 2", which is located in the Central foyer of the hospital. The procedure is carried out by a team of an obstetrician- gynecologist, a radiologist and an anesthesiologist (if anaesthetic is applied). During the procedure the woman is lying down with her knees bent.

After the preparation of the patient for the procedure (clean pubic area), and the placing of the speculum through the cervix, a contrast agent – dye, is injected via a thin metal catheter.

The substance passes through the uterine cavity, enters the fallopian tubes, and if there are no obstructions, is infused into the abdominal cavity, where it is absorbed safely by the body.

If the tubes are blocked, the contrast substance cannot pass freely through them. After the infusion of the substance, several consecutive X-rays are taken that show the dynamics of the filling of the uterine cavity and fallopian tubes.

Why is a HSG necessary?

Normal passable fallopian tubes are a prerequisite for the natural meeting between an egg and a sperm cell in order fertilization to occur.

When the tubes are blocked, this process is prevented and the expected pregnancy cannot happen.

The color image can give physicians information about some abnormalities of the inner surface of the uterus like fibroids, polyps, adhesions, which may impede implantation of the embryo and the successful maintaining of the pregnancy.

When is a HSG of the tubes necessary?

HSG is carried out in the first days after the menstrual cycle of a women when there is (no bleeding) before the ovulation to occur (up to the tenth day of the menstrual cycle).

Important: The first day of the menstrual cycle is considered to be the day with a clearly visible bleeding.

We recommend that:

You should make an appointment for a HSG in the early days of your menstruation. Previously, you will be informed about the tests that you need to do and all the documents (informed consent, anesthesia sheet, etc.), that you have to fill in.

When shouldn’t I have a HSG procedure?

  • If you are pregnant
  • If there is an active vaginal infection or pelvic inflammatory disease
  • During your menstrual bleeding
  • If you have an allergy to iodine- contrast agent

What may you feel?

You may have some pain similar to that in the early days of your monthly cycle. The pain intensity is strictly individual. In most cases, we recommend the use of pain medications that will be prescribed to you by your physician.

Can I have anesthesia in a HSG procedure?

Depending on your individual threshold of sensitivity, the procedure can be conducted under short intravenous anesthesia. For this purpose, you will be given a short pre- anesthesia consultation. On the day scheduled for the procedure, you should come to the hospital “hungry and thirsty” which means without having eaten any foods and taken any fluids.

How long will it last?

The procedure lasts about 15 minutes and the woman should remain in the surgery room after the procedure for about another 10 minutes (if the procedure has gone under anesthesia).

Important: For this procedure it is necessary the patient’s bladder to be empty.

Results from the HSC of the fallopian tubes:

The results are commented by your obstetrician-gynecologist at the time of your next visit, which you need to book in advance.

It is possible that you have the comments the same day if you have previously made an appointment for that day.

If you wish, you can have a paid copy of the recorded procedure on a CD.

Recommendations

It is possible that after the procedure you may have a slight bleeding but if the pain or the bleeding increases, you will need to visit the emergency room of the hospital.
