Sources and options for the formation of renal human veins

Abstract

The purpose of the study was to identify the sources and options for the formation of human renal veins according to corrosion preparations. One hundred forty-two corrosion preparations of human venous vessels of the kidneys have been manufactured. Sources and variants of the formation of renal veins relative to the sagittal, frontal and horizontal planes have been studied in stereoprojection. It has been found that most often the main renal vein is formed from two venous vessels (57.8 % of the cases) or from three venous blood vessels (31.0 % of the cases) at p ≤ 0.05. When the main renal vein is formed from two venous vessels, in 32.4 % of the cases it occurs when the upper pole and lower pole venous vessels merge. The second most common case (25.4 % of the cases) is the formation of the main renal vein from the ventral and dorsal venous vessels. When the main renal vein is formed from three vessels, in 15.5 % of the cases it is formed from the upper, central and lower pole venous vessels, in 8.4 % of the cases - from the upper pole, lower pole and dorsal central venous vessels; and in 4.2 % of the cases - from the ventral, dorsal and lower pole venous vessels. The remaining options for the formation of the main renal vein represent less than 5.0 % of the cases.
