Summary
A rare case of right renal artery triplication, including a superior polar artery and inferior polar artery, was found incidentally. This anatomical variation highlights the importance of understanding renal artery variants for surgical safety.
Area of Science:
- Anatomy
- Radiology
- Vascular Surgery
Background:
- Renal vasculature exhibits significant morphological variability, crucial for kidney-related procedures.
- Accurate anatomical knowledge of renal arteries (RA) is vital for preventing complications during interventions.
Observation:
- A computed tomography angiography (CTA) incidentally revealed a right-sided renal artery triplication originating from the abdominal aorta (AA).
- The triplication consisted of a main hilar artery (MHA), a superior polar artery (SPA), and an inferior polar artery (IPA).
Findings:
- Renal artery triplication, occurring in 0.9%-4.5% of individuals, presents diverse morphological patterns.
- This specific case represents a rare variant, featuring one SPA, one IPA, and one MHA.
Implications:
- Understanding rare renal artery variants like triplication is essential for surgeons.
- Knowledge of these anatomical variations aids in preventing iatrogenic injuries during kidney transplantation, endoscopic surgery, and renal angiography.

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 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 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...

2.3K
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

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...

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...
