Children's Hospital

We took Wyatt to Radiology at Children's Hospital today.  My pediatrician wanted to make sure that there's no leakage through his bladder.  Eric and I were standing next to Wyatt when they did the x-ray.  The radiologist said he didn't see any leakage.  Wyatt was crying the whole time.  When I looked at the screen, I didn't know what I was looking at.  I didn't know what that dark stuff was.  After they took out the tube, then I realized that's Wyatt's bladder.  As soon as they took out the tube, Wyatt peed and the black thing on the screen became very small.  

Afterwards, they gave Wyatt a stuffed teddy bear.  They told us to call my pediatrician's office tomorrow for the result.  I wonder if we still have to take him to Urology at Children's Hospital on Thursday.
