Vascular malformation of kidney - A case report

Author(s): Debajani Deka*, Amrita Nidhi, Nisha Yadav

Kidneys are two retroperitoneal paired organs situated at the level of L1, L2, L3 position. Superior aspect of kidney is within lower thoracic cage at the level of tenth rib. Right kidney is lower than the left kidney due to presence of liver. The adult kidney weights about 150gm. 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. On left side there is duplex ureter draining behind the renal vein. Here the left suprarenal vein is twisted and the gland is also showed lower down as the venacava is rotated down showing its posterior aspect and we are not getting any venous tributaries draining from it.
