This is the pediatric waiting room. You can read a book here or watch TV before your test.

Today the doctors are looking at your bladder. It is like a balloon inside your body that holds your pee before you go to the bathroom. The doctors want to make sure it is healthy and working the way it should.

Here is a picture of the room where you will have your test. There are lots of cabinets and a TV hanging from the ceiling. You will get to be on TV!

Here is our special camera that takes pictures (x-rays) of the inside of your belly. The doctor will pull it across your body and it will get close to you but it never touches.

Before we take your picture, we need you to put on a hospital gown. The adults with you will have to put a heavy (lead) apron on since we don't need pictures of their bellies today.

Here is the kind of picture our big camera takes, an x-ray. In order to see your bladder we have to put a special liquid in called contrast. It looks just like water.

For girls only: The technologists will help you to lie like a frog with your knees bent out to the sides and the bottom of your feet touching.

In order to get the contrast into your bladder the doctor must put a small tube into the hole that you pee out of. The first step is to clean this area of very well with brownish-orange soap. It is cold and wet. Next, the doctor will put some slippery jelly on the end of the tube and slide it up into your bladder. You may feel some discomfort but there are lots of ways to make this part easier.

Here is a picture similar to what you will see during your test. That big balloon at the bottom is a bladder filled with contrast. The doctors will ask you to hold it even though you may feel like you have to go to the bathroom. It is important for your bladder to be filled all the way.

Once you can't hold it anymore, the doctor will take a few more pictures and then ask you to void, or pee, on the table. The technologists will help you start to go by running the faucet or dripping warm water on your leg. There are towels under you so that you will not get messy. When your bladder is empty the doctor takes the last picture and then you are done!
