Purpose: Renal graft mass has been known as a determinant of the outcome after kidney transplantation. We evaluated the correlation between the donated kidney weight and the recipient’s creatinine clearance (Ccr), the donated kidney weight and serum creatinine (Scr) as well as the correlation between the donor traits and graft function after living-donor transplantation in adults.
Methods: The weight of a donated kidney was measured just after flushing during the operative procedures, and the recipient’s Scr was measured on a daily basis postoperatively. When the Scr of the recipient reached the baseline level, we collected the recipient’s 24-hour urine for the Ccr calculation. Based on the measured body weight and height, body surface area (BSA) and lean body weight (LBW) were calculated. Pearson correlation analysis was carried out using the SPSS.
Results: The weight of donated kidney was significantly correlated with the post-transplant recipient’s Ccr (P=0.022). Scr was significantly correlated with the variable of graft weight/ recipient body weight ratio (P=0.047, Pearson correlation=-0.539), graft weight/recipient BSA ratio (P=0.028, Pearson correlation=-0.438), graft weight./recipient LBW ratio (P=0.001, Pearson correlation=-0.603), donor body weight/recipient body weight ratio (P<0.001, Pearson correlation= 0.667), donorBSA/recipient BSA ratio (P<0.001, Pearson correlation=0.743), donor LBW/recipient LBW ratio (p<0.001 Pearson correlation=0.759).
Conclusion: It may be appropriate to select potential living donors based on the predicted size of the kidney, especially for the recipient who will likely to have higher metabolic demands.
