Simplified Method to Measure Renal Volume: The Best Correction Factor for the Ellipsoid Formula Volume Calculation in Pretransplant Computed Tomographic Live Donor

To avoid underestimation of the renal volume by the ellipsoid method, acceptable correction factors are in the range of 0.664 to 0.686. We suggest the use of a mean value of 0.674 or 0.67 as correction factor when using the ellipsoid formula.
