Kidney transplantation in older patients: benefits and risks.

The proportion of older patients accepted for dialysis is increasing every year both in the US and abroad. Of the two treatment modalities for end-stage renal disease, i.e. dialysis and transplantation, the latter offers more freedom and is associated with better clinical outcome. Most elderly patients seem to have excellent functional rehabilitation after a kidney transplant. However, in view of the wide gap between the availability of cadaver organs and the people in need, giving the precious organ to the elderly who have a shorter expected lifespan may present an ethical problem. Therefore, it has become increasingly important to offer the kidney to only those who have no significant comorbid conditions or other high risk factors, so as to improve the odds of success after renal transplantation.
