What is a Functional Renal Scan?

A Functional Renal Scan is an exam that evaluates the function of the entire urinary system.

This exam requires the use of a radiopharmaceutical through an IV catheter.

What should you do prior to your child's exam?

Your child should not have certain radiographic contrast media 24 hours prior to the exam.

Dress your child comfortably, in clothes that are easily removed. Your child may be given a gown to change into for the procedure.

We have a large variety of video entertainment to choose from, however, your child can also bring along his/her favorite video or DVD to watch during the exam.

You may want to bring a snack or drink for your child to have after the exam.

Note: Parents will be allowed to accompany the child into the exam room. It may be helpful to make other arrangements for siblings.

What should you do when you arrive?

If your appointment is scheduled at the Main Hospital:

You must check in to Outpatient Registration, on the third floor of the Main Hospital, 45 minutes prior to your scheduled appointment. This is where your registration process occurs.

The law requires that you bring a prescription from your doctor's office stating the exam to be done and the reason for it.

If your insurance requires a referral, it must be presented at the time of registration. Proof of insurance will also need to be provided at this time.

Once the registration process is completed, the Nuclear Medicine Department will be notified. A technologist or nurse will come out to the central registration area and bring you and your child to a room for IV placement.

If your appointment is scheduled at the Pediatric Imaging Center at King of Prussia:

You must check in at the main registration desk, located in the main waiting room, 45 minutes prior to your scheduled appointment. This is where your registration process occurs.

The law requires that you bring a prescription from your doctor's office stating the exam to be done and the reason for it.

If your insurance requires a referral, it must be presented at the time of registration. Proof of insurance will also need to be provided at this time.

Once the registration process is completed, you will be directed to the Radiology waiting room. The Nuclear Medicine technologist will be notified and a technologist or nurse will come out to the Radiology waiting room and bring you and your child to a room for IV placement.

What should you expect during the exam?

A technologist or nurse will place an IV in your child for the radiopharmaceutical (tracer) injection needed for this exam. This IV tube will be placed in the child's arm, hand, or foot. Your child will only feel a little discomfort, like a mild pinch. Once the child has proper IV access, the procedure can begin.

The technologist will ask why the Functional Renal Scan is being done, and explain the study to you and your child. Some children may require a urinary catheter, which will be placed by the technologist.

The technologist will inject the tracer through the IV line. A set of images will be taken lasting approximately 1 hour. Your child will have to lie still during the imaging portion of the test. The camera will be above the table and will come close to but will not touch your child. The nuclear medicine physician may then require additional imaging, after viewing the initial images. Further delayed imaging may be necessary.

IV fluids will be given during the exam to ensure that your child stays well hydrated.

Lasix will also be given during the imaging portion of the exam, through the IV previously placed. Lasix is a diuretic medication that makes the bladder and kidneys empty and it increases the urge to urinate.

Child Life Specialists are available to answer questions you might have about how to prepare and support your child during the procedure. A child life specialist can also be present at the time of your child's appointment to explain the procedure in developmentally appropriate ways using well established preparation materials.

What should you do after the exam?

There are no special instructions for your child to follow upon completion of this procedure.
