[|Human|] Hi Dr,Tommorow my mom is having a kidney biopsy.  She is 6 years out of tranplant and the kidney is spilling over  alot of protein.  Her creatine .06 and her BUN is fine.  also, I started to notice that her short term memory is going and I took her to 3 different nurologist and they all say that from the test there is no dementia or alzhalmer.  So, why would the fidney be leaking protein?  Is this normal?
[|AI|]  Protein loss from the kidneys is called albumin-urea, basically it indicates that the kidneys are not functioning properly and are not able to retain the proteins inside and are excreting the substances (proteins) which it should retain. There are many reasons of this condition, stating from entirely a normal phenomenon for someone with very small amount to a fairly advanced kidney disease in cases of huge protein loss. In case of post transplant patient, rejection (although it has been 6 years) to different kinds of glomerulonephritis can be the causative agents. I think biopsy is the way to go to see what exactly is the problem so that it can be fixed accordingly. THANKS and best of luck.
