About the intrarenal veins of right kidney
The right kidney is drained by an internal venous tree whose branches follow the arteries but join one another freely. The finest beginnings lie in the cortex. Capillaries that surround the convoluted tubules, fed by the efferent arterioles of the glomeruli, empty into interlobular veins; immediately beneath the capsule a ring of stellate veins drains the most superficial tissue into the same channels.
The interlobular veins descend through the cortex to the arcuate veins, arches that lie at the junction of cortex and medulla over the bases of the renal pyramids. The medulla sends its blood up to these arches through the venae rectae, straight vessels that run alongside the loops of Henle. The arcuate veins drain into interlobar veins, which pass between the pyramids within the renal columns and reach the renal sinus.
Inside the sinus the interlobar veins gather into larger trunks that usually lie in front of the renal pelvis. At the hilum these unite to form the right renal vein. On this side the renal vein is short and passes almost directly into the right side of the inferior vena cava, which lies close by.
Because the veins are connected to one another, particularly through the arcuate arches, venous drainage is not divided into the strict segments that the arteries define. A surgeon removing part of the kidney can tie off smaller intrarenal veins with less risk of harming the tissue left behind. The shortness of the right renal vein is a practical point in transplantation: surgeons generally prefer a left kidney from a living donor because its longer vein is easier to join to the recipient's vessels.
Course and drainage
- Begins at
- Begins in the peritubular capillaries and stellate veins of the cortex and the venae rectae of the medulla.
- Drains into
- Interlobar veins form trunks in the renal sinus that join at the hilum as the right renal vein, which enters the inferior vena cava.
- Drains
- Drains blood from the cortex and medulla of the right kidney.
