Transvaginal Ultrasound (Endovaginal Ultrasound)

A transvaginal ultrasound is an imaging test. An ultrasound uses sound waves to form pictures of your organs that can be seen on a screen. It's often done with a probe placed on the belly. A transvaginal ultrasound uses a special probe that is put into your vagina. It uses sound waves to make pictures of your uterus, ovaries, and other pelvic organs. This test can be used to check symptoms such as pain. It can also check for problems. In pregnant women, it's used to check the unborn baby or fetus. The test is often done by a specially trained technologist called a sonographer.

Getting ready for your test

You may be asked to go to the bathroom. Your bladder may need to be empty before the test.
Tell the sonographer what medicines you take. Let them know if you have had pelvic surgery.
Answer any other questions the sonographer asks. Your answers will help them adapt the test to your health needs.

During your test

You may change into a hospital gown. You'll then lie down on an exam table with your knees raised, as you would for a pelvic exam.
The sonographer will use a thin handheld probe. It's shaped like a tampon. The probe has a sterile cover and nongreasy gel. It's gently put inside your vagina. In some cases, you may be asked to put the probe in yourself, as you would a tampon.
The sonographer moves the probe to get the best picture. You may feel pressure. Tell the sonographer if you feel pain.
