LIVING DONOR
A living donor transplant is preferred to the deceased donor because these tend to be better quality kidneys in that the waitlist times tend to be low and graft survival is longer than deceased donor kidneys.
The half-life of transplanted kidney
living kidneys around 12–14 years
deceased donor is around 9 years.
The longer people wait for transplantation while on dialysis, the more unfavorable their outcomes are after transplant.
Ideally, patients would be transplanted before initiating dialysis, referred to as pre-emptive transplant, or as soon as possible after initiating dialysis.Patients can be listed for transplant when their glomerulus filtration rate is below 20 mL/min/m2.
DECASED DONOR
A deceased donor kidney comes from a person who has chosen to be an organ donor and has been declared deceased.
Like the living donor, the deceased donor must have blood testing performed to show compatibility with the proposed recipient.
The kidney transplant survival rate for the first year with a deceased donor kidney is 85 to 90 %.
The average functional time period of a deceased donor kidney transplant is between 8-20 years.
Statistics show that kidney transplants from live donors function longer and the survival rate for live donor kidneys is greater than 95 % for the first year.
The average life of a kidney donated from a perfectly matched (tissue typing identical) sibling is 25 to 30 years
the average life of a kidney donated from a half matched or unrelated donor is 16 years.

KIDNEY TRANSPLANT AND GENDER
DONOR-RECIPIENT GENDER
The most successful transplant based on donor-recipient gender was observed in male donor to male recipient, and then male donor to female recipient.
