What is the procedure advised for the correction of extreme renal failure? Give a brief account of it.

(N/A) The procedure advised for the correction of extreme renal failure is $Kidney$ $transplantation$.
In this process,a functional kidney is taken from a donor,preferably a close relative,to minimize the chances of rejection by the recipient's immune system.
The donor kidney is surgically transplanted into the recipient's body,where it takes over the function of filtering blood and maintaining homeostasis,effectively replacing the failed kidneys.
