Prolonged cold ischemia time (CIT) is one of the most common causes of acute tubular necrosis (ATN) with consequent delayed graft function after kidney transplantation. The aim of the study was to analyze the impact of early donor lymph nodes (LN) procurement in combination with local or central HLA typing on CIT, on donor-recipient HLA mismatches, and on the early results of grafts. Two hundred six cadaveric procedures were performed from 2001 to 2004 including 86 cases out of 119 recipients who were matched locally and 60 cases out of 87 recipients who were matched centrally, wherein LN were obtained before kidney harvest. CIT was significantly shorter when LN were obtained before kidney harvesting both in local (13.6 vs 20.6 hours) and central (20.1 vs 27.7 hours) matching (both P < .001). ATN frequency was significantly lower in patients with LN obtained earlier (27.9%) when matched locally versus (35.0%) when matched centrally. Kidney graft function estimated at 12 months was similar in both groups. CIT longer than 19.5 hours predicted ATN occurrence with 57.7% sensitivity and 66.4% specificity. Local matching resulted in shortening CIT compared to central matching (15.5 vs 22.4 hours); however, the mismatch in HLA class I and HLA class II were significantly worse (HLA A + B 2.76 vs 2.45, HLA DR 1.21 vs 0.82). These discrepancies did not significantly influence the frequency of ATN (36.1% vs 40.0%) or the kidney graft function at 12 months.
