Donating a kidney is a generous act that can save someone's life. But how long can people live after donating a kidney? The answer depends on several factors, including the type of donor and the recipient's health. The average long-term survival of kidneys from living donors is 12 to 20 years, compared to 7 to 8 years for those obtained from cadaver donors. People can live a normal life with just one kidney.
As long as the donor is thoroughly evaluated and the donation is authorized, they can lead a normal life after surgery. When the kidney is removed, the single normal kidney will increase in size to compensate for the loss of the donated kidney. Life expectancy after a kidney transplant varies depending on several factors. According to studies, 1-year survival rates for kidney transplants range from 93 to 98%, and 5-year survival rates range from 83 to 92%.
Patients who undergo a kidney transplant before dialysis live an average of 10 to 15 years longer than if they stayed on dialysis. Younger adults benefit the most from a kidney transplant, but even adults up to 75 years of age earn an average of four more years after the transplant than if they had stayed on dialysis.Donating a kidney doesn't affect a person's life expectancy. On the contrary, studies show that people who donate a kidney outlive the average population. Twenty years after the donation, 85 percent of kidney donors were still alive, while the expected survival rate was 66 percent.
This may be because only healthy people are approved to be donors, or perhaps donors take extra health precautions after donating a kidney.The kidney from a living donor works well for almost 15 to 20 years, while with a kidney from a deceased donor, life expectancy increases from 8 to 12 years. Since the average lifespan of a transplanted kidney is 15 to 20 years, if the kidney stops working, patients can be placed on a waiting list for a new one. The National Kidney Registry reports that in the United States, there are only three deaths out of every 10,000 transplants from living donors (mortality rate of 0.03 percent). The study showed that between 1 and 5% of current average age living kidney donors could develop ESRD as a result of nephrectomy.A kidney transplant is a surgical procedure in which a healthy kidney from a living or deceased donor is placed in a person whose kidneys no longer work.
We assume that many of the future risks that may affect life expectancy and ESRD, such as cancer, obesity, smoking, etc., were not influenced by the act of kidney donation. Causes of kidney failure may include diabetes, polycystic kidney disease (PKD), uncontrolled chronic high blood pressure (hypertension), or chronic glomerulonephritis (inflammation and, eventually, healing of the glomeruli, the tiny filters found inside the kidneys). Family members are often the most likely to be compatible living kidney donors, but many people have successful transplants with kidneys donated by people who are not related to them.Because a person can live with only one kidney, a living donation offers another option for some transplant candidates. After the donation, the living organ donor's remaining kidney will be enlarged, doing the work of 2 healthy kidneys.In conclusion, donating a kidney does not affect life expectancy and may even increase it.
The average lifespan of a transplanted kidney, whether from living or deceased donor, is 12 to 20 years. However, it is important to note that this varies depending on several factors such as age and health status.
