title: Is it appropriate to implant kidneys from elderly donors in young recipients?
abstract: BACKGROUND
  Kidneys from elderly donors tend to be implanted in recipients who are also elderly. We present the results obtained after 10 years of evolution on transplanting elderly kidneys into young recipients.
  
  
  METHODS
  Ninety-one consecutive transplants are studied, carried out in our center with kidneys from cadaver donors older than 60 years implanted in recipients younger than 60 years. The control group is made up of 91 transplants, matched with those from the study group, whose donor and recipient were younger than 60 years.
  
  
  RESULTS
  There were no differences between groups with regard to recipient age, sex, cause of death and renal function of the donor, hepatitis C and cytomegalovirus serologies, cold ischemia time, tubular necrosis, immediate diuresis, need for dialysis, human leukocyte antigen incompatibilities, hypersensitized patients, acute rejection, waiting time on dialysis, and days of admission. Survival in both groups at 1, 5, and 10 years was 97.6%, 87.2%, and 76.6% vs. 98.8%, 87.5%, and 69.5% for the patient (P=0.642), 92.9%, 81.3%, and 64.2% vs. 93.9%, 76.4%, and 69.5% for the graft (P=0.980), and 94.4%, 92.6%, and 77.4% vs. 94.3%, 86.7%, and 84.4% for the graft with death censured (P=0.747), respectively. Creatininaemias at 1, 5, and 10 years were 172, 175, and 210 vs. 139, 134, and 155 (P<0.05).
  
  
  CONCLUSIONS
  We conclude that patient and graft survival on transplanting kidneys from elderly donors to young recipients is superimposable on that obtained with young donors. However, renal function is better in the group of young donors.
