['Because kidneys show remarkable resilience and can recover function, we examined the impact on long-term graft survival in deceased donor renal transplants of both immediate graft function (IGF) and the rate of renal function recovery over the first 3 months after transplantation.', "We included all cadaveric renal transplants from 1990 to 2007 (n = 583). Delayed graft function (DGF) was defined as the need for dialysis in the first 7 days posttransplant. Slow graft function (SGF) and IGF were defined by serum creatinine falls of <20% or >20% in the first 24 hours posttransplant respectively. Recovery of renal function was expressed as either the best creatinine clearance (CrCl) in the first 3 months post-renal transplantation (BCrCl-3mos) as calculated using the Cockcroft-Gault formula or as a percentage of actual versus expected value (as calculated from the donors' CrCl at procurement).", 'There were 140 (23.6%) subjects who received extended criteria donor (ECD) organs. The overall graft survival at 1 and 5 years was 87.8% and 74%, respectively. The 5-year graft survivals for patients with IGF, SGF, and DGF were 85%, 76%, and 54%, respectively (P < .02). ECD kidneys showed twice the DGF rate (49% vs 23%, P < .001). BCrCl-3mos of <30 mL/min displayed a 5-year graft survival of 34%; 30 to 39 mL/min, 72%; 40 to 49 mL/min, 85%; and >50 mL/min, 82% (P < .001). Similarly, a recovery within 90% of expected CrCl in the first 3 months posttransplant correlated with 5-year graft survival of 81%; a recovery of 70% to 90%, with 65%; and a recovery of <70%, with 51% (P < .001).'] Does recovery of graft function early posttransplant determine long-term graft survival in deceased donor renal transplants?
