title: Living donor nephrectomy--no impact of genetic relationship.
abstract: OBJECTIVE
  A retrospective, single-center analysis was conducted to compare the results of living donor kidney transplantation between living unrelated (LURD) and living related (LRD) donors.
  
  
  METHODS
  One hundred forty-seven consecutive living renal transplantations were performed at our institution, starting in 1983. Graft and patient survival were assessed as well as transplant function, including a subgroup analysis for the period of kidney transplantation.
  
  
  RESULTS
  Mean follow up for the LRD group was 88.5 months and for the LURD cohort 34.4 months. One- and 3-year graft survival (censored for death with functioning graft) for LRD versus LURD was 97.5% versus 94.4% (P =.4) and 95.3% versus 88.8% (P =.35). Patient survival at 1 and 3 years was 95.1% versus 94.7% (P =.91) and 87.8% versus 90.0% (P =.79). Of the related recipients, 37% experienced at least one episode of rejection in the first year following renal transplantation, compared to 34% in the LURD group (P =.80). Mean serum creatinine for LRD versus LURD after 1, 3, and 12 months () was 1.52 +/- 0.81 versus 1.59 +/- 1.17 mg/dL (P =.98), 1.41 +/- 0.55 versus 1.30 +/- 0.40 mg/dL (P =.51), and 1.44 +/- 0.39 versus 1.40 +/- 0.40 mg/dL (P =.75). Mean creatinine clearance after 1 year was 82.2 versus 71.7 mL/min (P =.26). Subgroup analysis for the time between 1996 and 2002 revealed no difference between LURD and LRD. Multivariate analysis could exclude an impact of the significantly different recipient age and of first/second warm ischemic time on the endpoints described above.
  
  
  CONCLUSIONS
  LURD is a good way to meet the growing organ shortage and should be encouraged.
