When Your Child Needs a Pelvic Ultrasound

Your child needs to have a pelvic ultrasound. An ultrasound is a type of imaging test. It uses high-frequency sound waves to make images of organs and other structures inside the body. It can be used on many parts of the body, including the pelvis, the area between the hips.

Why a pelvic ultrasound in done

A child may need a pelvic ultrasound:

  • To look for masses, such as kidney stones, cysts, fibroids, or tumors

  • To figure out what is causing symptoms, such as pelvic pain

  • To check the organs in the pelvis, such as the bladder or uterus

  • To find out what is causing early or delayed puberty

How a pelvic ultrasound is done

Your child will likely not have to do anything special to get ready for a pelvic ultrasound. In some cases, your child’s healthcare provider may ask that your child drink water beforehand, so your child has a full bladder.

A pelvic ultrasound is often done in a radiology department or center. A healthcare provider called a radiologist does the test. It takes about 30 minutes.

During the pelvic ultrasound:

  • Your child will first change into a gown.

  • Your child will then lie down on an exam table. The lights may be dimmed in the room. This helps the radiologist see the images as they appear on a video screen.

  • The radiologist will put some warm gel on your child’s lower stomach, or pelvic area. The gel helps the sound waves travel through the body.

  • The radiologist will move a wand, or transducer, back and forth over the skin on your child’s pelvic area. As he or she does so, the transducer will emit sound waves. It will then pick up the sound waves as they echo or bounce back.

  • A computer will turn the sound waves into images. The images will appear on a video screen. They show the organs and other structures in real time.

  • At points during the test, the radiologist may ask your child to move into different positions or to hold his or her breath for a short time.

  • Once the test is done, the radiologist will wipe off the gel.

During the pelvic ultrasound, your child will need to stay still as much as possible. Moving around too much can distort the images. If you have a younger child, distracting your child during the test may help. Try bringing along a stuffed animal or some other toy.

What happens after a pelvic ultrasound

Your child can go back to normal activities after the test. The radiologist may give you the results right away. Or you may get the results in a few days from your child’s healthcare provider.

Risks of a pelvic ultrasound

A pelvic ultrasound is a safe and painless test. It has no risks.
