I have done a couple of research and from what I have read, kidney failure can be reversed.
It is by the use of a bone protein, bone morphogenic protein-7(BMP-7) to be exact. Studies shows that BMP-7 can decrease bad cells and converting them into good cells.
Here's a link to the site:

And if this doesn't suit you, you can look for a kidney donor so that you can undergo a kidney transplant. Until that time, you can undergo dialysis to keep your blood clean.
