introductionA kidney transplant is the transfer of a healthy kidney from one person ,the donor, into the body of a person who has little, or no, kidney activity ,the recipient,. A person only needs one kidney to survive, and some people are born with only one working kidney. Therefore, the donor can be living, or recently deceased.
It is sometimes necessary for patients to make their decision whether they want a kidney transplant or not. It is more efficient than dialysis (which we have suggested above) though it is carried out outside the body and performs the functions of the failed kidneys, such as regulating fluid balance.
A kidney transplant allows people to live without the need of the dialysis even after their own kidneys have stopped working, and with fewer restrictions on what they can eat and drink.
There is some evidence that people who have successful kidney transplants live longer than if they were having dialysis treatment. However, the main advantage of a kidney transplant is that a patient’s quality of life is much better than it would be if they were to be permanently on dialysis.

Though kidney transplant can very safe but sometimes body rejects and destroys foreign substances. This remarkable ability is called immunity. When harmful bacteria or other foreign substances enter the body, certain tissues make a protein antibody, which helps destroy the foreign substance.
When the new kidney is transplanted your body might think it is a foreign body it treats the new kidney as it would any other foreign substance. When the immune system attacks the transplanted kidney, it is called rejection.
Sometimes donor are performed for a related living kidney, it could be from the father, the mother, the son, sister, brother etc. Also it is almost much safer than have a donor from elsewhere but sometimes when the related donor does not fit a foreign donor can be performed but the chance can be very low.
