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

The procedure advised for the correction of extreme renal failure is kidney transplantation.

A functioning kidney is used in transplantation from a living donor or can also be from a deceased donor ( only if the deceased has just died can their kidneys be used for the transplantation) . The kidney should be preferably from a close relative so that the immune system does not reject it. Donor compatibility is evaluated via blood tests that matches the blood types and antigens.
