What do you do if, accidentally, you scan the abdomen of a neonate and find nephrocalcinosis? Book them in for a transplant in a couple of years? Annual serum electrolytes, blood pressure & isotopic GFR measurement? Pretend you hadn’t seen it?

As an oncologist, I really haven’t the faintest idea what to do with this finding. (I’d pop into EBM-free mode and call the nephrologist who I know has a good track record in EBM and hope they knew the answer.) However, Jon Kim and colleagues are taking this by the horns and determining the answer. Well, trying anyway.

What do you do?
