In my experience, the most common cause of an immediate transplant failure is a clot in the blood vessels to the kidney. The surgeons will see if they can remove the clot and save the kidney, but if it cannot be saved, the kidney will be removed.

Can a rejected organ be reused?

Why are transplanted organs rejected?

When a patient receives an organ transplant, the immune system often identifies the donor organ as “foreign” and targets it with T cells and antibodies made by B cells. Over time, these T cells and antibodies damage the organ, and may cause reduced organ function or organ failure. This is known as organ rejection.

Do organ transplants last forever?

How an organ transplant will affect a person’s life expectancy varies depending on their age, the organ transplanted, and the reason for the transplant. Not all transplanted organs last forever. A kidney from a living donor lasts an average of 12–20 years, whereas a kidney from a deceased donor lasts around 8–12 years.
