What is aberrant renal?
Aberrant renal arteries are common in fused kidneys. Aberrant arteries perforate the substance of the kidney rather than entering its hilum to supply it. They arise as separate branches from the aorta or as branches of the renal artery, inferior suprarenal, inferior phrenic or superior mesenteric artery.
What does Malrotated kidney mean?
When the kidney fails to rotate or over-rotates, this is known as malrotation and can affect one or both kidneys. Malrotation occurs in 1 in 939 autopsies and can be divided into non-rotation, incomplete rotation, reverse rotation, transverse rotation or excessive rotation [1].
What passes through hilum of kidney?
This fissure is a hilum that transmits the vessels, nerves, and ureter. From anterior to posterior, the renal vein exits, the renal artery enters, and the renal pelvis exits the kidney.
What is the renal hilus?
The hilus is the point of entry and exit of the renal arteries and veins, lymphatic vessels, nerves, and the enlarged upper extension of the ureters.
Why do I have a Malrotated kidney?
The exact cause of malrotation of the kidneys is unclear, though it has been hypothesized that malrotation may occur if the ureteric bud inserts into an abnormal region of metanephric mesenchyme. Its association with renal ectopia suggests that the process of ascent and rotation are related.
What is the function of column of Bertini?
The renal column (or Bertin column, or column of Bertin) is a medullary extension of the renal cortex in between the renal pyramids. It allows the cortex to be better anchored. Each column consists of lines of blood vessels and urinary tubes and a fibrous material.
What is the function of the hilum?
The hilum is what connects your lungs to their supporting structures and where pulmonary vessels enter and exit your lungs. The hilum — or root — functions much like a plant root, securing each lung in place and providing a channel for energy to pass through.
Is Hilus and hilum the same thing?
In human anatomy, the hilum (/ˈhaɪləm/; plural hila), sometimes formerly called a hilus (/ˈhaɪləs/; plural hili), is a depression or fissure where structures such as blood vessels and nerves enter an organ.
Which is an aberrant artery supplying the kidney hilum?
aberrant renal artery : supplying the superior and/or inferior pole of the kidney accessory renal artery : supplying the renal hilum Accessory renal arteries occur bilaterally in 10-15% of cases: single renal artery arising from the abdominal aorta: 70%
Where are the singular and accessory renal arteries located?
The normal, singular renal artery occurs in about 70% of cases, while an accessory renal artery is present in about 30% of cases. The accessory renal artery most commonly arises just below, or in some cases, above the main renal artery.
What are the branches of the renal hilum?
Branches. The dorsal and ventral rami divide into segmental branches within the renal hilum before entering the parenchyma: apical, anterior superior, anterior inferior (middle), inferior and posterior segmental renal arteries. These then divide into lobar branches which successively branch into interlobar, arcuate, and interlobular arteries.
What causes the hardening of the renal arteries?
The two main causes of renal artery stenosis include: Atherosclerosis of the renal arteries. Atherosclerosis is the buildup of fats, cholesterol and other substances (plaques) in and on your artery walls. As the deposits get larger, they can harden, reduce blood flow and cause scarring of the kidney.
