neprocalinosis, newly diagnosed. Advice?

Hello all. I am a 26 year old male who is being treated for a Carcinoid Tumor. I ended up in the ER with bad vomitting and had a renal ultrasound because of blood in urine. It showed this "Ended up in the ER with vomitting and blood in the urine. A ultrasound of my kidneys showed this: "Cortical thinning bilaterally with prominent echogenicity in the renal medulla bilaterally. This would suggest the possibility of early or developing medullary nephrocalcinosis. Clinical correlation is advised." 

ER doctor sent me home and told me to followup with my oncologist and primary. Anyone have similar issues? " 

Right kidney measured 8.6 cm in length, and left kidney was 9.4 cm in length. 

Er doctor wants me to followup about the ultrasound with treating doctors. What does all that mean? Not sure if it is something to worry about. 

This could possibly mean kidney stones, calcium deposits in and round the kidney. Please note......could......indicate this. If it is it depends on the size of them. They can pass in urune with no problem, they may pass uncomfortably, or the may surgically remove them or try to flush them out. Again, that is IF they are kidney stones. They need to be addressed clinically.

Presumably you know the location(s) of the carcinoid tumour(s)? If not, this episode of vomiting and discovery of problem with your kidneys might be quite helpful to define where your carcinoid tumour is?
