What is a renogram with Vasotec?
This test looks at how the kidneys are working. Kidneys help filter waste from the body and produce urine. Kidney function may also affect a person's blood pressure. Vasotec is a medicine that helps determine possible reasons for high blood pressure that might be related to how the kidneys work.
The test is done in the Nuclear Medicine department using special camera equipment. It gives very little radiation to your child. A radioisotope (a clear liquid that allows us to see only the function of the organ we are looking at) is given into your child's vein. It travels through the bloodstream to the kidneys. Your child will not feel the medicine or any side effects from it. The camera detects gamma rays (invisible radiation) coming from the radioisotope and creates the images (pictures) on film.
How is the test done?
A technologist will bring you and your child into an exam room and explain the test to you both. You and your child will meet the radiology nurse, who will weigh your child, check your child's blood pressure and ask about allergies. The nurse will start an IV in a vein, usually in the arm or hand. This involves a little poke, using a small IV (intravenous) needle. Once the IV is in place, the needle is removed and a tiny plastic tube stays in the vein during the test. It should not bother your child once it is taped down. Staff will work with you and your child to plan the best way to support your child when the IV is put in.
During the time you are with the nurse, your child will have blood pressure checks and be given something to drink or some fluids through the IV. The Vasotec will be given into the IV 30 minutes before the radioisotope in given.
About 30 minutes after the Vasotec has been given into the IV, you and your child will go to the Nuclear Medicine scanning room. In the scanning room the lights will be dimmed, and your will child lie comfortably on the imaging bed (a lightly padded table). You may stand by your child's head to provide support and distraction. The radioisotope will be given into the IV, and the nurse will continue to check your child's blood pressure.
Many children watch a movie (we have DVDs and videotapes here), listen to a story read by a parent, or simply rest during this time.
A radiologist will check to see if any more images are needed before you leave, and will send a report to your child's doctor.
Can I be with my child during the test?
You are welcome to stay with your child. The total time for this test is about 3 hours. If your doctor has ordered sedation for your child, plan on a total of 4 hours. See the education sheet, "Nitrous oxide for sedation."
What should we do before the test?
Some medicines interfere with this test. Ask your doctor if your child is taking any ACE inhibitors or Angiotensin II receptors. If your child is on any of these medicines, call Radiology and ask to speak with a Nuclear Medicine technologist. Please call at least 5 days before your child's test.
Usually you can maintain your child's routine eating, sleeping, and medicine schedules before the test. It is very helpful if your child drinks two extra glasses of liquid (such as water or juice) a few hours before the test.
Your child's doctor or a Children's staff member may give you different instructions if your child will have more tests on the same day.
Read and discuss this information with your child. Answer as many questions as you can.
To learn more about preparing and helping your child cope with this test, call the child life department. Child life specialists are trained to help children understand and cope with medical procedures and can offer advice on how to talk with and support your children. There is no charge for child life.

How should I prepare my child?
Children are usually less afraid and feel more successful when they know what to expect and what is expected of them. You know your child best. The amount of detail you give will depend on your child's age and developmental level, reactions to previous health care experiences, and degree of anxiety about this test. Talking about it can help your child be more comfortable with the test, which will make the procedure easier for both of you.
Most children benefit when you use simple words to explain:
- why the test is needed: "To help find out how your kidneys are working."
- what parts of the body will be involved: "Your kidneys are the parts that make your pee/urine" (use the words familiar to your child).
- what your child might see, hear, and feel. For example, "arm hugs" for blood pressure checks, small poke for the IV, lying still under the camera.
- that it is okay for staff to touch your childs body for this test.
- where parents or other significant care providers will be during the test: "I/we will be with you the whole time."
- that questions are welcome at any time.
For many children, a big concern is whether or not the test will hurt. Assure them that although there may be some discomfort, it will only last a few moments. Remind them that the test is important because it helps find out how their body is working inside.
How can I support my child during this test?
Before the appointment, you and your child can:
- practice lying down and being "as still as a statue."
- practice relaxing. Imagine being in a favorite place or doing a favorite activity.
- pack comfort items, such as a stuffed toy or blanket, some familiar books or quiet toys, a pacifier for very young children. Older children and teens may want to bring an iPod® or a hand-held video game.
- talk about how much your child wants to know about the test while it's happening. Some children want to be told each step in advance and also while it's happening. Others do not want all the detail; they simply want to be distracted and supported. Be sure to share your child's wishes with the staff once you are here.
During the test
Research is clear that parents are most helpful to their children during stressful times when they offer distraction, rather than apologies.
- Praise your child often during the test. Be specific to behaviors, such as "You're holding still. Good for you!" or "You're doing just what we asked you to do!"
- Talk about familiar, positive things – what your child likes, places you've enjoyed, activities you're planning as a family, fun times you've had, successes.
- Imagine the places, things, or people you're talking about and describe them, or have your child describe them to you. Ask open-ended questions that encourage conversation rather than those that require just a yes or no answer. For example, "Tell me what you'd like to do when we go to the pool" works better than, "We're going to have a great time when we go swimming, aren't we?"
- Sing songs together. Play games that require thinking, such as spelling words or adding and subtracting out loud. Ask young children such things as which animals live on a farm or in the zoo and the sounds they make, or to name all the people in their family or class, and so on.
- Read the books you brought, hold a toy so your child can see and play with it, play "Can you guess?" and give clues about people and pets you know, things you see in the room.
What can we expect after the test?
If sedation was used, your child will need to be monitored by a nurse until awake. Your child may go back to normal eating and activity after this test.
You will receive the results from the doctor who ordered the test.
What else do we need to know?
On the day before the test, you may pre-register online at www.childrensmn.org. Please do this before 3 p.m. If you prefer, you can call the admitting office.

Children's - St. Paul, 1st floor
Plan to allow extra time before the appointment, to check your children into the Sibling Play Area.
