Thanks for all of the prayers and well wishes. It went so well! Not only did she do great (she was the life of the radiology department that day) she didn't show any signs of kidney reflux!
Here she is in her hospital gown.
She didn't even cry when they inserted the catheter! Amazing little girl! (It was sort of funny because she DID cry during her renal u/s at the urologist's office. Which, clearly, didn't hurt. She was just plain mad.)
We still have to watch out for unexplained high fevers, but we're sort of professionals at fever watch. :)
