How the Test is Performed
You will lie down on your back on a table with your knees bent. Your feet may be held in stirrups.
The ultrasound technician or doctor will introduce a probe into the vagina. It may be mildly uncomfortable, but will not hurt. The probe is covered with a condom and a gel.
- The probe transmits sound waves and records the reflections of those waves off body structures. The ultrasound machine creates an image of the body part.
- The image is displayed on the ultrasound machine. In many offices, the patient can see the image also.
- The provider will gently move the probe around 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
In most cases, there is no pain. 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
-
Normal Results
The pelvic structures or fetus is 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
- Benign growths in or around the uterus and ovaries (such as cysts or fibroids)
- Endometriosis
- Pregnancy outside of the uterus (ectopic pregnancy)
- 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.
