A pelvic (transabdominal) ultrasound is an imaging test. It is used to examine organs in the pelvis.
How the Test is Performed
During the procedure, you will lie on your back on the table. Your health care provider will apply a clear gel on your abdomen.
Your provider will place a probe (transducer), over the gel, rubbing back and forth across your belly:
- The probe sends out sound waves, which go through the gel and reflect off body structures. A computer receives these waves and uses them to create a picture.
- Your provider can see the picture on a TV monitor.
Depending on the reason for the test, women also may have a transvaginal ultrasound during the same visit.
Transvaginal ultrasound
Transvaginal ultrasound is a test used to look at a woman's uterus, ovaries, tubes, cervix and pelvic area. Transvaginal means across or through the ...
How to Prepare for the Test
A pelvic ultrasound may be done with a full bladder. Having a full bladder can help with looking at organs, such as the womb (uterus), within your pelvis. You may be asked to drink a few glasses of water to fill your bladder. You should wait until after the test to urinate.
How the Test will Feel
The test is painless and easy to tolerate. The conducting gel may feel a little cold and wet.
Why the Test is Performed
A pelvic ultrasound is used during pregnancy to check the baby.
A pelvic ultrasound also may be done for the following:
-
Cysts,
fibroid tumors
, or other growths or masses in the pelvis found when your doctor examines you
Fibroid tumors
Uterine fibroids are tumors that grow in a woman's womb (uterus). These growths are typically not cancerous (benign).
- Bladder growths or other problems
- Kidney stones
- Pelvic inflammatory disease, an infection of a woman's uterus, ovaries, or tubes
- Abnormal vaginal bleeding
- Menstrual problems
- Problems becoming pregnant (infertility)
- Normal pregnancy
-
Ectopic pregnancy
, a pregnancy that occurs outside the uterus
Ectopic pregnancy
An ectopic pregnancy is a pregnancy that occurs outside the womb (uterus). It is life-threatening to the mother.
- Pelvic pain
Pelvic ultrasound is also used during a
biopsy
to help guide the needle.
Biopsy
A biopsy is the removal of a small piece of tissue for laboratory examination.
Normal Results
The pelvic structures or fetus are normal.
What Abnormal Results Mean
An abnormal result may be due to many conditions. Some problems that may be seen include:
- Abscess in the ovaries, fallopian tubes, or pelvis
-
Birth defects of the womb or vagina
