Three stickers attached to a computer by wires are put on your child; one on each side of the anus and one on the hip bone. When your child feels like their bladder is full, they will urinate into a special toilet that collects and measures the urine. The toilet is in an exam room and not in a bathroom, but the nurse or nurse practitioner may not need to be in the room when your child is urinating.
After your child has urinated, the nurse practitioner will gently remove the stickers. Then an ultrasound machine will be used by the nurse practitioner to find out how much urine is left over in your child’s bladder.
