title: Kidney retransplantation in comparison with first kidney transplantation.
abstract: BACKGROUND
  The aim of this study was to depict the outcome of second and third kidney allografts in comparison with first kidney allografts.
  
  
  METHODS
  Among 2150 kidney transplantations are 103 second and 5 third transplantations. Demographic characteristics and survivals of retransplanted patients were compared with a randomly selected group of first kidney recipients, consisting of two cases matched with each retransplanted patient for age, gender, and date of transplantation.
  
  
  RESULTS
  Retransplanted patients consisted of 78 men and 30 women of mean age 32.63 +/- 11.92 years. They had received kidneys from 91 living-unrelated and 17 living-related donors. Median followup was 27 months. One-, 2-, 3-, and 5-year graft survivals were 81.4%, 78.9%, 78.9%, and 73.7% among retransplants, versus 92.9%, 91.5%, 89.8%, and 85.3% in the control group, respectively (P = .0037). Patient survival was 96%, 94.6%, 92.4%, and 87.8% in the retransplant group versus 93.1%, 92.4%, 90.9%, 87.4% in the control group, respectively (P = .63). Also, graft survivals were slightly lower in female compared to male retransplant patients (P = .09). No significant difference in survival rates was seen in different age groups.
  
  
  CONCLUSIONS
  It seems that kidney retransplantation can yield desirable outcomes, albeit relatively lower graft survivals.
