Summary
Accessory renal arteries vary significantly by ethnicity, ranging from 4% in Malaysia to 61.5% in Brazil. This anatomical variation is crucial knowledge for surgeons and interventional radiologists.
Area of Science:
- Anatomy
- Vascular Biology
- Medical Imaging
Background:
- Accessory renal arteries are anatomical variations with potential clinical significance.
- Understanding their prevalence is vital for surgical and interventional procedures.
Purpose of the Study:
- To systematically analyze and synthesize existing literature on the frequency of accessory renal arteries.
- To highlight ethnic and demographic variations in their occurrence.
Main Methods:
- Systematic literature review of published papers.
- Analysis of data based on ethnicity, age (fetuses vs. adults), and imaging techniques.
Main Results:
- Incidence varies widely, from 4% (Malaysian) to 61.5% (Brazilian) populations.
- Lower frequencies observed in Eastern and Southern Asia (4%-18.4%).
- Higher frequency in fetuses than adults; imaging techniques (CT vs. dissection) impact reported numbers.
Conclusions:
- Significant ethnic and age-related variations in accessory renal artery prevalence exist.
- Imaging modality influences reported frequencies, impacting anatomical accuracy.
- Knowledge of accessory renal arteries is critical for modern surgical interventions, particularly laparoscopic procedures.

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...

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...

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.

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

01:25Abdominal Aorta
3.1K
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...

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...
