HyFoSy Assessment at QUFW

Transcript:

Hi, my name’s Jacqui. I’m the lead gynaecological sonographer for QUFW. I’m here to talk you through your HyFoSy examination at QUFW.

HyFoSy is a specialised gynaecology ultrasound procedure used as part of a fertility assessment. It provides information about the internal cavity of the uterus and the fallopian tubes. A contrast agent, ExEm foam, is used to visualise the tubes. It is made from a gel and purified water which, when mixed, create a foam used to detect any blockages in the fallopian tubes.

Why are patent fallopian tubes important?

The fallopian tubes are an essential part of a woman’s reproductive system, connecting the ovaries to the uterus. Open (or patent) fallopian tubes are important for conception. If both tubes are blocked, the sperm and egg cannot meet, making conception impossible. The fallopian tubes cannot be visualised on a standard ultrasound, which is why the HyFoSy procedure is used.

When the procedure is performed

The procedure should be performed between four to ten days after the first day of your last menstrual period. We recommend calling our office on day one of your period to make a booking. If you have irregular or infrequent cycles, please call for individual advice.

Some patients may be asked to avoid sexual intercourse before the procedure and/or have a pregnancy blood test. You do not need a full bladder for the examination. It’s recommended that you take your usual pain relief about one hour before your appointment. You may bring a support person if you wish, although this is not required.

What happens on the day

On arrival, you’ll be asked to perform a urine pregnancy test to confirm you are not pregnant. A transvaginal ultrasound is done first. Once this is complete, the doctor will insert a speculum and place a thin, flexible catheter through your cervix into the uterus. As the catheter passes through, you may feel some discomfort or cramping. Once it’s in position, a small balloon at the end of the catheter is inflated, which may cause mild pressure that should ease quickly.

The speculum is then removed and the transvaginal probe reinserted so we can visualise the procedure. Saline (a sterile saltwater solution) is passed through the catheter to check the uterine cavity for scarring, polyps, or fibroids that may not be visible on regular ultrasound. Then, the contrast agent (ExEm foam) is passed through the catheter. The doctor observes the contrast as it moves through the uterine cavity and fallopian tubes. The goal is to see the contrast flow through open tubes and spill into the area surrounding the ovaries.

When the procedure is finished, the catheter and probe are removed.

What to expect during a HyFoSy

Some patients may feel light-headed, hot, or dizzy during the procedure. Mild cramping, similar to period pain, is also common. These symptoms usually settle quickly, and pain relief can help if needed. Please tell your doctor or sonographer if you feel unwell, and they’ll help you feel more comfortable.

How long it takes

We allow 45 to 60 minutes for the appointment, including preparation and scanning time. The actual procedure usually takes about 10 minutes.

When you’ll receive your results

As the procedure is performed, the doctor will explain the findings and whether the tubes appear open. Occasionally, results may be inconclusive if it’s difficult to distinguish between tubal spasm and blockage.

Your results will be sent directly to your referring doctor, and you’ll also receive a copy via a secure link through Tricefy on your mobile. The time taken for your doctor to receive the written report will depend on the complexity of the examination and whether additional findings were noted.

After the procedure

You may notice some watery or light bloody discharge afterward. This is normal and due to the saline and contrast used. A sanitary pad will be provided. Mild bloating, cramping, or lower abdominal discomfort can occur and is usually relieved with standard pain medication. Light bleeding or spotting may continue for a day or two.

If you experience severe pelvic pain, fever, or an unusual vaginal discharge that is green or yellow, contact your GP or referring doctor promptly, as these may be signs of infection (which is uncommon).

It is safe to resume normal activities, including intercourse, after the procedure. The HyFoSy is a very safe procedure that does not involve ionising radiation or general anaesthetic.
