title: Living related and unrelated donors for kidney transplantation. A 28-year experience.
abstract: OBJECTIVE
  The objective of this study was to analyze a single center's 28-year experience with 1000 living donor transplants.
  
  
  BACKGROUND
  The number of potential renal transplant recipients far exceeds the number of cadaveric donors. For this reason, living related donors (LRDs) and, more recently, living unrelated donors (LURDs) have been used to decrease the cadaveric donor shortage.
  
  
  METHODS
  From November 15, 1966, until August 5, 1994, 1000 living donor transplants were performed; 906 were living related and 94 were living unrelated transplants. Results were divided into precyclosporine (1966-1986, era I) and cyclosporine (1986-1994, era II) eras. Patient and graft survivals were compared between diabetic and nondiabetic recipients, between LRDs and LURDs, and according to human leukocyte antigen (HLA) matching. Donor mortality, morbidity, and postoperative renal function were also analyzed.
  
  
  RESULTS
  The 5-, 10-, and 20-year graft survivals were 78.8%, 64.8%, and 43.4%, respectively. Patient and graft survival improved in era II (patient = 87.0% vs. 81.7%, p = 0.03; graft = 72.9% vs. 67.7%, p = 0.04). Nondiabetic patient and graft survivals were better than diabetic patient survivals in both eras. However, diabetic patient survival improved in era II (78.0% vs. 66.9%, p = 0.04). In era II, HLA-identical recipients had better graft survival than haploidentical or mismatched recipients (91.7% vs. 67.3% and 66.1%, p = 0.01). No difference between haploidentical LRDs and LURDs was seen. One donor death occurred in 1970, and 17% of donors developed postoperative complications.
  
  
  CONCLUSIONS
  Living related and unrelated renal donation continues to be an important source of kidneys for patients with end-stage renal disease.
