A kidney transplant does not last for ever. The average life-span of a transplanted kidney is twelve years for a deceased donor kidney, and about 15 years for a living related transplant. The average for a living unrelated transplant is somewhere between the two.
But the drugs themselves put patients at heightened risk for infection, cancer, diabetes and high blood pressure. Plus, they can themselves be toxic to the kidney. And sometimes they just donât work. Even in the case of the best immunological recipient/donor match-ups, a new kidney lasts 25 to 30 years on average.
