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.
The waiting time for a kidney-pancreas transplant varies from person to person and can be affected by your blood type and how long it takes for a suitable deceased donor to become available. The average wait for a simultaneous kidney and pancreas is about 3 years. As of September 2013, there are more than 2,000 candidates listed on the national waiting list awaiting a kidney-pancreas transplant.
