The stellate veins are minute [1] veins situated just beneath the fibrous capsule of the kidney. [citation needed] The stellate veins drain the superficial-most portion of the renal cortex. Groups of 5 or 6 stellate veins are arranged in a star-like pattern, converging centrally to drain into an interlobular vein as it penetrates into the renal ...

The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla. [1] In the adult, it forms a continuous smooth outer zone with a number of projections (cortical columns) that extend down between the pyramids.
The venous drainage of the kidney large mirrors its arterial supply, except that there are no segmental veins. [4] The stellate veins arise from the capillaries, then drain successively through interlobular veins and interlobar veins until these converge from across the kidney to form the renal vein for that kidney.
Visualization of blood flow in the renal arteries (those supplying the kidneys) in patients with high blood pressure and those suspected of having kidney disorders can be performed using CTA. Stenosis (narrowing) of a renal artery is a cause of hypertension (high blood pressure) in some patients and can be corrected.
One renal vein drains each kidney. [citation needed] A renal vein is situated anterior to its corresponding accompanying renal artery.The renal veins empty into the inferior vena cava, entering it at nearly a 90° angle.
Urology addresses diseases of kidney (and urinary tract) anatomy: these include cancer, renal cysts, kidney stones and ureteral stones, and urinary tract obstruction. [ 7 ] The word “ renal ” is an adjective meaning “relating to the kidneys”, and its roots are French or late Latin.
