What is Transvaginal Ultrasound (TVS)

Transvaginal ultrasound, also called an endovaginal ultrasound, is a test that uses harmless sound waves to take pictures of the female genital tract. The pictures are taken with a device, called a transducer, that is placed in the vagina.

This test may be done to:

• Check for problems with your pregnancy.
• Examine your developing baby.
• Check for anything abnormal in the uterus or ovaries.
• Evaluate pelvic pain or bleeding.

Tell a health care provider about:

• Any allergies you have.
• All medicines you are taking, including vitamins, herbs, eye drops, creams, and over-the-counter medicines.
• Any blood disorders you have.
• Any surgeries you have had.
• Any medical conditions you have.
• Whether you are pregnant or may be pregnant.
• Whether you are having your period.

What are the risks?

There are no known risks or complications of having this test.

What happens before the procedure?

• This test needs to be done when your bladder is empty. Follow your health care provider’s instructions about drinking fluids and emptying your bladder before the test.

What happens during the procedure?

• You will empty your bladder.
• You will undress from the waist down.
• You will lie down on an examining table, with your knees bent and your feet in foot holders.
• A health care provider will cover the transducer with a sterile condom.
• A gel will be put on the transducer. The gel helps transmit the sound waves and prevents irritation to your vagina.
• The technician will insert the transducer into your vagina to get images. These will be displayed on a monitor that looks like a small television screen.
• The transducer will be removed when the procedure is complete.

What happens after the procedure?

• It is your responsibility to get your test results. Ask your health care provider or the department performing the test when your results will be ready.
• Keep follow-up visits as told by your health care provider. This is important.
