MODEL RELEASED. Kidney transplant. Image 12 of 17. Close-up of surgeons performing a kidney transplant operation. The kidney is being sutured in place. Kidneys are transplanted to replace a failing or failed kidney. It is the safest and most commonly performed organ transplant. It has a high success rate, although recipients do need to take immunosuppressant drugs for the rest of their life to prevent rejection. The donor kidney may come from a living or recently deceased donor and can be kept viable outside of the body for several days.
