Abstract:
Objective To explore the significance of time-zero renal biopsy on evaluating renal function and postoperative complications after transplantation from donation in old age donors.Methods Clinical and pathological data of 112 transplantations with time-zero renal biopsy which performed in the First Affiliated Hospital of Zhengzhou Hospital from August 2016 to April 2017 were collected.Based on donor age and Remuzzi score,112 transplantations were divided into four groups:Group A (donor age ＜50 years and Remuzzi score is 0 to 3) with 58 recipients,Group B (donor age ＜50 years and score is 4 to 6) with 9 recipients,Group C (donor age≥50 years and score is 0 to 3) with 35 recipients,and Group D (donor age≥50 years and score is 4 to 60) with 10 recipients.Renal function and postoperative complications of recipients in each group were recorded and compared among groups.Results The estimated glomerular filtration rate (eGFR) at 6th month after operation was significantly negatively correlated with glomerular sclerosis (r=-0.398,P=0.05),arteriolar hyaline degeneration (r=-0.416,P＜0.05) and arterial intimal fibrosis (r=-0.242,P＜0.05).Arteriolar hyaline degeneration (β=-0.249,P＜0.05) and arterial intimal fibrosis (β=-0.246,P=0.020) were the independent correlated factors of eGFR at 6th month after operation.The levels of serum creatinine of group D were higher than those in the other three groups at each time after operation(all P＜0.05);Moreover,in group D the eGFR values at each time were lower than those in the other three groups(P＜0.05).Additionally,the incidences of acute rejection within 6 months after operation in group C and D were higher than those in group A and B (all P＜0.05),but the incidences of delayed graft function,hematuria,proteinuria among four groups were not significantly different (all P＞ 0.05).Conclusions Patients who accepted older kidney with moderate histological lesions show worse renal function and higher incidence of acute rejection after transplantation.Recipient selection and postoperative immunosuppressive treatment should be more cautious for those renal donors.
