Yes James had this done when he was about 2 days old!
I think the MCU was for reflux which James didn't have. He had a further test when he was 7 days old which was called a MAG3 which Jordan may also need. This shows if there is any blockages in the kidneys.
James just got home yesterday from having his kidney operation yesterday. Both kidneys were too big so the operation was on both sides. I guess you are going to the Children's? Do you have a Urologist yet? If so who are they?
Cheers
