Abstrakt		Background. The kidney size reflects the number of nephrons. In the majority of the chronic renal parenchymal diseases the kidneys shrink in size as the function and the nephron number decrease. The assessment of the renal size and especially renal parenchymal volume can help us in predicting the potential reversebility or irreversibility of renal failure. Purpose. The aim of our prospective clinical study was to assess the volume of renal parenchyma in healty adult volunteers, using renal ultrasound, establish the distribution of renal parenchymal volume right to left and to choose the method of measurements to obtain the optimal results. Subjects and method. 20 healthy volunteers, 10 men and 10 women, participated in the study. The principle of determing renal parenchymal volume was to measure the volume of the whole kidney and reduce it by the volume of central pyelovascular area, the difference representing the renal parenchymal volume. Two different methods of renal volume assessment were used ("quick" method 1, using cardiologic software for calculation of left ventricular volume, already being incorporated in Acuson 128 XP/10 ultrasound monitor) and method 2, classical threedimensional method, calculating renal volume according to ellipsoid formula from renal length and two transversal diameters. Within every method the renal dimensions were measured with volunteers supine and prone. Results. 1.The average values for renal parenchymal volume are higher for men, although there were no statistically significant differences in renal parenchymal volume among men and women (p=0,20 for right kidney, p=0,53 for left kidney). 2. We established statistically significant correlation of right renal parenchymal volume with body weight (r=0,55 , p=0,01) and body surface area (r=0,51 , p=0,02). 3.The ellipsoid method was found to have less deviations from the reference method compared to "cardiological" method. 4.
