Morphological studies of the valves of the kidney vein in domestic swine.
It was established macroscopically that 37.5% of the renal veins investigated possess valves. Valves were observed on both sides, but predominantly on the left side of the kidneys (14.58%). Some valves were also observed in the main branches of the renal veins. The structure of the valves was studied with the use of light and electron microscopy. The most important finding was the observation of mast cells in the valves. This is probably a common biological phenomenon, since mast cells have been observed in the cardiac valves and the wall of the renal artery and vein.
