    Transvaginal ultrasound

    Endovaginal ultrasound; Ultrasound - transvaginal

    Transvaginal ultrasound is a test used to look at a woman's reproductive organs, including the uterus, ovaries, and cervix.

    Transvaginal means across or through the vagina.

    How the Test is Performed

    You will lie down on a table with your knees bent. Your feet may be held in stirrups.

    You will be given a probe, called a transducer, to place into the vagina. The probe is covered with a condom and a gel.

    • The probe sends out sound waves, which reflect off body structures. A computer receives these waves and uses them to create a picture.
    • The ultrasoundtechnician ordoctor can see the picture on a TV monitor.
    • The health care provider will move the probearound the area to see the pelvic organs.

    In some cases, a special transvaginal ultrasound method called saline infusion sonography (SIS) may be needed to more clearly view the uterus.

    How to Prepare for the Test

    You will be asked to undress, usually from the waist down. A transvaginal ultrasound is done with your bladder empty or partly filled.

    How the Test Will Feel

    The test is usually painless, although some women may have mild discomfort from the pressure of the probe. Only a small part of the probe is placed into the vagina.

    Why the Test is Performed

    Transvaginal ultrasound may be done for the following problems:

    • Abnormal findings on a physical exam, such as cysts, fibroid tumors, or other growths
    • Abnormal vaginal bleeding and menstrual problems
    • Certain types of infertility
    • Ectopic pregnancy
    • Pelvic pain

    Transvaginal ultrasound is also used during pregnancy.

    Normal Results

    The pelvic structures or fetusis normal.

    What Abnormal Results Mean

    An abnormal result may be due to many conditions. Some problems that may be seen include:

    • Birth defects
    • Cancers of the uterus, ovaries, vagina, and other pelvic structures
    • Infection, including pelvic inflammatory disease
    • Growthsin or aroundthe uterus and ovaries (such as cysts or fibroids)
    • Twisting of the ovaries

    Risks

    There are no known harmful effects of transvaginal ultrasound on humans.

    Unlike traditional x-rays, there is no radiation exposure with this test.
