I am unable to make a specific diagnosis based on the information that you present. The first thing that is needed to try and make a specific diagnosis as to the cause of the kidney disease. In some cases this may be acute kidney disease, which might be reversible. If this is chronic kidney disease (CKD) then treatment may be needed such as dialysis or transplantation. In most cases, further testing and perhaps a kidney biopsy could be necessary to tell the difference between acute and CKD. I suggest that you await an opinion of the nephrologist so as to develop a specific diagnosis and then treatment recommendations should follow from the specific diagnosis.
