A Case Report on Vascular Malformation of Kidney

The kidneys are a pair of retroperitoneal organs located at the level of the L1, L2, and L3 positions. At the level of the tenth rib, the superior portion of the kidney is located within the lower thoracic cage. Due to the existence of the liver, the right kidney is lower than the left kidney. The adult kidney weights about 150 gm. Right kidney is broad and short and left kidney is narrow and long. Right renal artery is longer than the left renal artery and right renal vein is shorter than the left renal vein. Renal arteries are end arteries while veins anastomose freely. Left gonadal vein and left suprarenal vein (adrenal vein) drain into the left renal vein. Right suprarenal vein and gonadal vein drain into inferior vena cava. Both the ureters are draining from the kidneys behind the renal artery. From anterior to posterior we get renal vein, renal artery and ureter.

In this case report we found pair of kidney with renal vein and renal artery. Right renal artery is longer than the left renal artery and left renal vein is longer than the right renal vein. We can see the posterior aspect of inferior vena cava.Left gonadal vein and left suprarenal vein (adrenal vein) are draining into the left renal vein. Right suprarenal vein and gonadal vein are draining into inferior vena cava. Both the ureters are draining from lower end behind the renal artery. From anterior to posterior we get renal artery, renal vein and ureter. Here we are getting duplication of ureter in the left side. On right side, there three accessory renal arteries, one to the inferior pole and two to the hilum behind the main renal artery of the kidney. On the left side, there are two renal arteries one going to the hilum behind the main renal artery and one going to the inferior pole of the kidney. On right side ureter is draining behind the renal vein. The duplex ureter drains behind the renal vein on the left side. The left suprarenal vein is twisted here, and the gland is also visible farther down because the venacava is turned down, revealing its posterior aspect, and no venous tributaries flow from it.
