A pelvic or obstetrical ultrasound is a diagnostic test using sound waves to check the organs in the low abdomen.
Gel will be applied to your pelvic area by the technologist. A small instrument will be moved across your skin. Silent sound waves pass through the body's organs, and echoes are shown as a picture on film. Tissue, blood, bone, and fluid all produce different echoes.
Ultrasound is not radiation like x-rays are. Ultrasound has been used for medical testing since the 1960's and has shown no harmful effects to patients or their unborn babies.
Outpatient - Preparing for your Obstetrical/Pelvic Ultrasound
During your ultrasound, the technologist will be scanning all of your pelvic and lower abdominal anatomy including, if you are pregnant, your unborn child's growth. Obtaining a good test for you and your doctor is our priority. For that reason, proper preparation is needed. A full bladder is needed for your test, as this helps the sound waves and allows for better viewing of the pelvic organs and/or of your growing baby. For your test, we ask that:
- You eat a light meal until one hour before your exam.
- One hour prior to your test, drink 32 oz. of fluid within a 10-minute time frame. No carbonated beverages (pop or beer), or milk.
- During the next 45 minutes, your bladder will begin to fill. DO NOT GO TO THE RESTROOM (urinate).
Drink 32-40 oz. of water within a 10 minute time frame 1 hour prior to test. DO NOT VOID.
If you are unable to drink fluids:
- You will need to have a Foley catheter inserted to fill your bladder.
- or, you will need to have your IV fluids increased to fill your bladder (this may take several hours). DO NOT VOID
For Your Information
- This test will not hurt you or your baby.
- You may be asked to change into a hospital gown.
- Relax and follow the directions given to you by the Medical Imaging staff.
- For an obstetrical (OB) ultrasound, a limited number of family members may be in the test room.
- You will be allowed to leave the Medical Imaging Department when the test is finished.
- The Radiologist (x-ray doctor) will "read" the x-rays and give the results to your doctor in 2-3 days. Your doctor will talk to you about the results of this test; feel free to ask the doctor if you have any questions.
