Hysterosalpingography (HSG)

About Hysterosalpingography

HSG (Hysterosalpingography) is an x-ray procedure that is used to view the inside of the uterus and fallopian tubes. It gives information about the shape of the cavity of the uterus and helps determine if fibroids are distorting the cavity of the uterus.

Your doctor may also refer you to Lake Imaging to determine if fallopian tubes are open or blocked. No information is obtained regarding the ovaries or outer contour of the uterus as part of an HSG procedure. Women who have a normal hysterosalpingogram have increased fertility rates after the procedure. This is believed to result from a "flushing" out the fallopian tubes that occurs in the HSG procedure.

Your appointment and preparation

A referral from your doctor and an appointment are required for an HSG examination.

This test should be performed between day 8 and day 10 of the menstrual cycle.

Please advise us if you have had a previous allergic reaction to x-ray contrast.

What can I expect during a Hysterosalpingography?

Before the procedure begins you will be asked to change from your clothes into a simple gown so that folds of clothing and metal fasteners do not interfere with the production of clear x-ray images. You will be asked to lie on the examination table.

The radiologist (a specialist medical imaging doctor) will insert a smooth, curved speculum, just like for a pap smear and cleanse the cervix with antiseptic. A thin catheter (tube) will be inserted into your cervical canal. Some women feel slight cramping during this part of the procedure. A tiny balloon will be inflated to hold the catheter into position.  The Radiologist will then remove the speculum. A small amount of contrast dye will be injected through the catheter in order to fill the uterine cavity. A series of live x-ray images will be taken while the dye is injected and the Radiologist will watch to observe if the contrast flows through one or both tubes. If the fallopian tubes are open, the dye will flow through them and spill into the belly where it will be absorbed naturally by the body. After the images are taken, balloon will be deflated and the catheter removed.

This procedure usually takes around 30 minutes.

What are the risks and side effects?

As with any medical procedure there is always a chance of complication. Infection resulting from this procedure is extremely rare, but on rare occasions, a person may have an allergic reaction to the x-ray contrast.  

X-rays require the use of ionising radiation.  As with all x-rays, there is always a slight risk as you will receive a small dose of radiation.  X-rays are only performed where it is deemed the benefit of the examination will outweigh any potential risks. At Lake Imaging you can be assured that using the latest technology and with staff trained in radiation reduction techniques, radiation doses are kept as low as reasonably possible.  Our state of the art x-ray equipment uses minimal amounts of x-rays to produce the best quality images for a diagnosis.

If it is possible that you may be pregnant, please tell our radiology team before your x-rays are taken to avoid any risks to your unborn child.

Who will perform my HSG and write the report?

At Lake Imaging your examination will be carried out by a Radiologist (a medical doctor specialising in the interpretation of medical images), who will then prepare and send a report to your referring doctor detailing the findings of your examination.

What should I expect after my examination?

Once your examination is complete you will be free to leave and return to normal activity. You may drive yourself home and eat and drink normally.

Some women will have slight cramping throughout the first day after the procedure.  The x-ray contrast is clear and sticky so throughout the day, expect a discharge of contrast. Slight bleeding is no cause for concern.

Please contact our clinic or your local doctor if you experience any concerning symptoms.

Most women are ovulating days after the HSG you may try and conceive unless your doctor has instructed otherwise.

How do I obtain my results?

If medically urgent, or you have an appointment immediately after your examination to see your referring doctor or health care provider, Lake imaging will arrange to have your results available immediately.  Otherwise, your referring doctor or health care provider will receive your report within 48 hours of your examination.

Please ensure that you make a follow up appointment with your referring doctor or health care provider to discuss your results.
