Blood and Nerve Supply to the Kidney

Blood and Nerve Supply to the Kidney

The kidneys are vital organs responsible for filtering and cleaning blood, removing waste products, and regulating electrolyte levels. To perform these essential functions, they require a constant and robust blood supply.
Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of each...

Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

External Anatomy of the Kidney

External Anatomy of the Kidney

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Abdominal Aorta

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Kidney Structure

Kidney Structure

The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

Internal Anatomy of the Kidney

Internal Anatomy of the Kidney

The kidneys are essential organs in the human body, performing a myriad of tasks that maintain homeostasis and overall health.
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
Renal Cortex
The outermost region of the kidney is the...

Area of Science:

Vascular anatomy
Radiology
Medical imaging

Background:

Renal artery anatomy is crucial for surgical and diagnostic procedures.
Variations in renal artery patterns can impact clinical interventions.
Understanding anatomical differences between right and left renal arteries is important.

Purpose of the Study:

To determine the pattern and character of renal arteries using multi-detector computed tomography (MDCT).
To compare the arterial anatomy of right and left kidneys.
To evaluate the effect of anatomical position on renal artery characteristics.

Main Methods:

A cross-sectional study involving 117 patients.
Contrast-enhanced 64-slice MDCT renal angiography was performed.
Assessment included number of arteries, branches, accessory arteries, and early branching.

Main Results:

No significant difference in diameter or branching distance between left and right renal arteries.
Accessory renal arteries were significantly more common on the right side (32.47%) than the left (17.09%).
Early branching was observed in 35.89% of subjects, with no significant difference between sides.

Conclusions:

Renal artery anatomy is largely symmetrical, with no significant differences in diameter or branching distance.
Accessory renal arteries show a higher prevalence on the right side.
MDCT angiography is effective for evaluating renal artery patterns and variations.
