The issue I am trying to understand is why the doctors would be telling him his kidney function is going to improve.. If they told him that that means he does not have kidney scarring. His condition will improve due to medication and diet management, but the kidney itself will never improve function. As I said in my previous post, once your glomerulus is damaged thats it, theres nothing that can be done to bring back their function. That's what leads me to believe there may be some discrepancy in the reporting maybe it's not actually kidney scarring.
