Of the types of kidney transplants, the cadaveric renal transplant and living donor kidney transplant is so differentiated owing to the nature of the donor whether deceased or alive respectively. It makes sense for you to get your kidney or kidneys replaced with a healthy kidney before you would have to get on dialysis and such a procedure is called a preemptive kidney transplant.
