Predictors of long-term renal function in living kidney donors are a matter of debate. To describe the predictors of remaining kidney functional gain, we conducted a prospective monocentric study of 63 living kidney donors who had 51Cr-EDTA-measured glomerular filtration rate (mGFR), split renal function by scintigraphy and for volume of the remaining kidney measured by renal CT-scan prior to donationand mGFR at a mean of 5.7±0.5 years after donation. We hypothesized that mGFR of the remaining kidney divided by the volume of this kidney (mGFR/vol) would reflect the density of functional nephrons and would be, consequently, inversely associated with functional gain. The mean mGFR was 97.6±13.0 before donation and was 63.8±9.4 ml/min/1.73 m2 at 5 years. Functional gain averaged 16.2±7.2 ml/min/1.73m2 (+35.3±16.7%). Multivariate analysis showed that age, BMI, and mGFR/vol at donation were negatively correlated with functional gain and had strong predictive power (R squared=0.409) of 5-year functional gain. We confirmed the predictive value of the initial mGFR/vol in an external validation cohort of 39 living donors. In conclusion, for a given age and BMI, living kidney donors will experience a lower 5-year functional gain when they have a greater mGFR/vol at donation.
