Abstract:
Objective To explore the correlation between post-transplant glomerular filtration rate (GFR) in 1 year and long-term graft survival in renal transplant patients.Methods The clinical data of 334 patients who received their cadaveric kidney transplantations between November 1994 and October 2004 were analyzed retrospectively.According to the GFR at one year after transplant operation, normal GFR group was defined as GFR more than or equal to 1.083 ml/s, while patients whose GFR less than 1.083 ml/s were fallen into abnormal GFR group.Cockeroft-Gault (C-G) formula was used to compare the difference in the renal function between the two groups.Kaplan-Meier assay was used to compare the difference in the allograft survival between the two groups in the functional renal allograft or the non-functional renal allograft.The correlativity of GFR level at the first year and the GFR level at the 5th year was analyzed.Results The GFR level at the first year after transplantation was proportional to the graft survival time of the kidney.Five and ten years after transplantation, the renal transplantation long-term survival rate in the normal renal function groups was significantly higher than in the abnormal renal function groups (P＜0.05).As compared with the GFR level at the first year after transplantation, the changes in amplitude of GFR level at the 5th year after transplantation was (0.080 ±0.248) ml/s, and the descent had a positive correlation with GFR level at the 5th year after transplantatioa Conclusion GFR level at the first year after transplantation predicts long-term renal functioa The higher of GFR level at the first year, the higher of GFR level at the 5th year.
