Early post-transplant renal allograft function between 1990 and 1998 in Spain.

Background: The last decade has witnessed a sustained improvement of renal allograft survival that is partly explained by a better preservation of renal allograft function. This study describes time-dependent modifications of serum creatinine (SCr) during the first year after transplantation in the last decade in Spain and characterizes the predictive value of SCr on death-censored graft survival.

Methods: A total of 3365 adult patients transplanted in 1990 (n = 824), 1994 (n = 1075) and 1998 (n = 1466) with a functioning graft after the first year were included.
