Summary
This study details kidney arterial segmentation in 194 human kidneys, revealing variations in renal artery branching patterns. Findings highlight common distributions of renal arterial segments crucial for anatomical understanding.
Area of Science:
- Anatomy
- Urology
- Radiology
Background:
- Understanding the arterial segmentation of the kidney is fundamental for surgical procedures and interpreting imaging studies.
- Previous studies have described variations, but a comprehensive analysis of renal artery branching patterns is essential.
Purpose of the Study:
- To investigate the arterial segmentation of the kidney.
- To observe the branching patterns of renal arteries and the distribution of second-order arteries within the renal parenchyma.
Main Methods:
- Analysis of 194 human kidneys obtained through evisceration.
- Utilized dissection and plastic material injection followed by corrosion for detailed arterial visualization.
- Correlated findings with renal angiographies.
Main Results:
- Identified variations in renal arterial segmentation, with 3, 4, 5, or 6 distinct arterial segments observed.
- The most common finding was 5 arterial segments (42.78%), including apical, superior, middle, inferior, and posterior.
- Detailed the specific nomenclature and percentages for each identified segmentation pattern.
Conclusions:
- The study demonstrates significant variability in human kidney arterial segmentation.
- Established a detailed classification of renal arterial segments based on observed patterns.
- These findings contribute to a better understanding of renal vascular anatomy.

01:18Blood 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...

01:19Imaging 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...
01:21External 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...

01:25Abdominal 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.

01:45Kidney 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.

The upper urinary system comprises two kidneys and two ureters, which are crucial in filtering blood and forming urine.KidneysLocation and Structure:The kidneys are two bean-shaped organs positioned behind the peritoneum on either side of the spine.Kidneys are between the 12th thoracic (T12) and the 3rd lumbar (L3) vertebrae.The position of the liver causes the right kidney to sit slightly lower than the left.Protective Layers:Each kidney is enveloped in a tough, fibrous membrane called the...
