Kidney transplant
A kidney transplant is the transfer of a healthy kidney from one person into the body of a person who has little or no kidney function. The main role of the kidneys is to filter waste products from the blood and convert them to urine.
Ideally, a kidney transplant should be performed when tests show that the extent of damage to your kidneys is so great that you'll need dialysis within the next six months. Most people with kidney failure need dialysis while they wait for a donated kidney to become available.
When a suitable donor kidney is found, the transplant centre will contact you. Staff at the centre will check you don't have any new medical problems and  then ask you to go to the centre. The kidney transplant procedure involves three main stages
Lifestyle advice is usually recommended to help you stay healthy after a kidney transplant. You should quit smoking, avoid eating foods that carry a high risk of food poisoning, start doing moderate-intensity exercise every week, etc
Although rates of serious complications have fallen sharply in the last few decades, kidney transplants like any other type of surgery are not risk-free. The risks of a kidney transplant include: risks related to the procedure itself, risks related to the use of immunosuppressant medications, etc.
