A NEW CONCEPT OF ZONAL AND SEGMENTAL STRUCTURE OF THE HUMAN KIDNEY

To date, there is no single point of view on the lobar, zonal and segmental structure arterial tree kidney. There generally accepted approach in determining signs by which kidney divided into lobes and/or segments. still a discussion regarding division renal artery to daughter branches. The aim study was establish variants individual anatomical variability intra-organ bed kidney, taking account topography. 116 corrosive preparations system human were studied. In 3D projections, number vessels hilum topographic features trunks arteries arteries, zones local blood supply areas substance depending branches 2nd 3rd orders. carried out using digital visualization methods, image processing appropriate software. As result, it found that can be two (two-zonal kidney) three (three-zone arteries. case bizonal system, divides ventral dorsal (54,2% cases), as well superior polar inferior (15,5% cases). three-zone following options for have been established. first option - upper polar, (in 13,3% cases); ventral, lower 9,4% variant one 5,1% cases) 4th pole, central pole 2,5% results convincingly indicate need revise widespread idea ​​the five-segment
