Volumetric Analysis of Stone Burden: Comparative Evaluation of the Accuracy of Contemporary Volume Determination Tools.
INTRODUCTION Historically, ellipsoid formulae (EF) based on maximum linear measurements (MLMs) have been utilized for stone volume determination; however, the irregular shapes of renal calculi may introduce inaccuracy. Recent advances in CT-based volumetric assessment tools, including 3D Slicer® (3DS), Enterprise Imagi...
