Living-Donor Kidney Transplantation: Donor-Recipient Function Correlation

With the rising prevalence of living-donor kidney transplantation, evaluation of factors correlated with renal function in the donor-recipient pair constitutes a main goal for kidney transplantation clinicians. Our objective was to analyze the more relevant donor characteristics that contribute to donor and recipient estimated glomerular filtration rates (eGFR) after 1 year. We evaluated 48 consecutive donor-recipient pairs from our unit. Mean donor age was 46 ± 11 years, with 71% being women. Mean recipient age was 35 ± 12 years, with 54% being men. Mean duration of donor hospitalization was 7 ± 2 days. Donor eGFR was 104 ± 11 mL/min/1.73 m2 before donation and 70 ± 14 mL/min/1.73 m2 at discharge. After 1 year, donor eGFR was 71 ± 12 mL/min/1.73 m2 and recipient eGFR was 69 ± 10 mL/min/1.73 m2. Donor eGFR 50 years correlated with 17.7- and 8.9-fold increased risks, respectively, of recipient eGFR
