Kidney transplantation is a surgical procedure to place a healthy kidney from a living or dead donor in a person whose kidneys are no longer working properly.
The main function of the kidneys is to filter and remove waste products, minerals and fluids from the blood by producing urine.
When your kidneys lose this ability to filter, harmful levels of fluid and waste accumulate in your body, which can raise your blood pressure and lead to kidney failure (end-stage kidney disease). The end stage of kidney disease occurs when the kidneys have lost about 90% of their ability to function normally.
Common causes of end-stage kidney disease are:
Chronic and uncontrolled blood pressure
Chronic glomerulonephritis – inflammation and possible ulcers of fine filters inside your kidneys (glomerulus)
Polycystic kidney disease
People who are in the final stages of kidney disease must be removed from their bloodstream through a device (dialysis) or a kidney transplant to survive.
Why is this over?
Kidney transplantation is often the treatment of choice for kidney failure, compared to a lifetime on dialysis. A kidney transplant can cure chronic kidney disease or end-stage kidney disease to help you feel better and live longer.
Compared to dialysis, kidney transplantation is associated with the following:
- Better quality of life
- Less risk of death
- Less dietary restrictions
- Lower treatment costs
Some people may also benefit from a kidney transplant before they need dialysis, a procedure known as a preventative kidney transplant.
But for certain people with kidney failure, kidney transplants may be more risky than dialysis. Conditions that may prevent you from being eligible for a kidney transplant include the following:
Severe heart disease
Active or recently treated cancer
Poorly controlled dementia or mental illness
Su Al consumes alcohol or drugs
Any other factor that can affect the ability to perform the operation safely and take the drugs needed after the transplant to prevent organ rejection
Only one donated kidney is needed to replace two defective kidneys, making a kidney transplant an option for the living donor.
Live kidney donation
Family members are often more likely to make living kidney donors. But successful life donor transplants are also common in kidneys donated from unrelated people such as friends, colleagues or members of a religious community.
Success rate for kidney transplantation
If your new kidney fails, you can resume dialysis or consider a second transplant. You can also stop treatment. If you decide to stop treatment, your doctor can give you medication to relieve your symptoms. This decision depends on your current health, ability to withstand surgery, and your expectations of maintaining a certain quality of life.
