The Correlation of Renal Allograft Weight to Metabolic Index Ratios and Glomerular Filtration Rate Among Living-Unrelated Kidney Transplant Patients: A Cross-Sectional Study

The RAW/RBW and RAW/RBMI correlated with GFR measures by the aMDRD method. Of the 3 ratios, only RAW/RBW was useful to predict GFR, best estimated by the aMDRD formula. A minimum RAW/RBW ratio of 8.2 predicted a good GFR at 6 months posttransplant. The findings suggested that transplanting a small kidney into a heavy patient may be a risk factor for allograft failure and that having a high initial ratio (≥8.2) of renal allograft weight to initial recipient body weight was an advantage.
