Transvaginal ultrasound scan

Find out what a transvaginal ultrasound scan is, how you have it and what happens afterwards.

What is an ultrasound?

Ultrasound scans use high frequency sound waves to create a picture of a part of the body. The ultrasound scanner has a microphone that gives off sound waves. The sound waves bounce off the organs inside your body, and are picked up again by the microphone. The microphone links to a computer. This turns the sound waves into a picture.

A transvaginal ultrasound scan can show up changes in your womb, ovaries or surrounding structures. For example, thickening of the womb lining.

Preparing for your scan

There is no special preparation before having a transvaginal ultrasound.

You just need to empty your bladder before the scan.

What happens

You usually have this scan in the imaging department or gynaecological outpatient clinic.

A doctor (radiologist) or sonographer will do your scan. A sonographer is a trained professional who specialises in ultrasound scanning.

When you are in the scan room, they’ll ask you to undress from the waist down. You can wear a hospital gown or they’ll give you a sheet to cover yourself with.

You lie on your back on the scanning couch with your knees bent and legs apart. If this position is difficult for you, you may be able to lie on your side with your knees drawn up to your chest.

The doctor or sonographer puts a protective cover over the slim ultrasound probe and covers it with lubricating gel.

They gently put the probe into the lower part of your vagina. This doesn’t hurt but it may feel slightly uncomfortable as they move the probe around. If you’d prefer, you can put the probe in yourself, similar to putting in a tampon.

The scan takes around 15 minutes.

Sometimes, you might have an ultrasound probe put on your tummy (abdomen) as well (abdominal ultrasound). You usually need a full bladder for this.

After your scan

The doctor or sonographer will give you a tissue to wipe away any gel. You can get dressed and usually go home straight away.

Possible risks

An ultrasound scan is a safe test.

You may have some slight discomfort during the scan.

Getting your results

You should get your results within 1 or 2 weeks. The doctor who arranged the scan will give them to you.

Some hospitals have specialist post menopausal bleeding clinics where you get the results the same day, and you can have further tests if needed.

If you have abnormal changes in your womb, you’ll need a biopsy to find out the cause. Your doctor takes samples of the womb lining. They send them to the lab to be looked at closely under the microscope.

Waiting for test results can be worrying. It may help to talk to a close friend or relative about how you feel.

You can also call the Cancer Research UK nurses on freephone 0808 800 4040. The lines are open from 9am to 5pm, Monday to Friday.
