Based on these anatomical features, perirenal fat regulates the cardiovascular system presumably via neural reflex, adipokine secretion, and fat-kidney interaction.
What is the difference between Perirenal and Pararenal fat?
The paranephric body (or paranephric fat or pararenal fat) is collection of adipose tissue located superficial to the renal fascia. The perirenal fat, or adipose capsule of kidney, is deep to the renal fascia but superficial to the renal capsule.
What is perineal fat?
The adipose capsule of kidney (or perinephric fat or perirenal fat) is a structure between the renal fascia and renal capsule, and may be regarded as a part of the latter. A different structure, the pararenal fat, is the adipose tissue superficial to the renal fascia.
What is epididymal fat?
The epididymal fat is an anatomically distinct and metabolically active abdominal fat depot widely used to study adipose tissue biology in rodents [2–12]. The paired epididymal fat is attached caudally to the ipsilateral testis and epididymis and extends proximally toward the diaphragm (Figure 1).
Is perirenal fat visceral fat?
Perirenal fat is a morphologically atypical visceral fat, but it is highly active in adipokine synthesis. 79-81 The adipokines that are synthesized and secreted by perirenal fat are listed in Table 3.
What lies between the Perirenal and Pararenal fat layers?
The renal fascia separates the adipose capsule of kidney from the overlying pararenal fat. The deeper layers below the renal fascia are, in order, the adipose capsule (or perirenal fat), the renal capsule and finally the parenchyma of the renal cortex.

What is the importance of the parietal fat capsule that surrounds the kidney?
The renal capsule is a tough fibrous layer surrounding the kidney and covered in a layer of perirenal fat known as the adipose capsule of kidney. The adipose capsule is sometimes included in the structure of the renal capsule. It provides some protection from trauma and damage.
What is Perirenal fascia?
The perirenal fascia is a dense, elastic connective tissue sheath that envelops each kidney and adrenal gland together with a layer of surrounding perirenal fat forming the perirenal space.
Where is perirenal fat located?
A layer of perirenal fat surrounds each kidney. This fat is encapsulated by the Gerota fascia.
What is the Perinephric and Paranephric fat?
There are two fat tissue layers covering the kidneys. The more superficial layer is called the perinephric (perirenal) fat lies between the renal fascia and the renal capsule and the deeper fat tissue layer which is also referred as the paranephric fat lies superior to the renal fascia.
What causes fibrous fat?
While fibrous fat can be genetic, most was fluffy fat under constant pressure from poorly fitting clothes or sitting. Fibrous fat is difficult to remove with non-surgical options. Liposuction works great because it destroys the network of fibers that forms in and around the fat cells.
How does fat attached to the body?
It functions as a padding to protect your muscles and bones from the impact of hits or falls. It serves as a passageway for nerves and blood vessels between your skin and your muscles. It insulates your body, helping it regulate temperature.
How do you lose ectopic fat?
A healthy lifestyle is the most appropriate therapy. In obese and T2D patients, caloric restriction, either after bariatric surgery or very low-calorie diet, has been found effective in reducing the amount of ectopic fat, mainly in liver and pancreas, and in improving fasting and postprandial hyperglycemia [3.
How thick is perirenal fat?
based on thresh-holding that found a smaller area of sinus adipose tissue. Indeed, Foster et al. reported median values of 0.97 (0.73, 1.34) cm2, whereas we found a mean of 3.44 ± 2.33 cm2 in our population (right side of body).
How does Nephroptosis affect urinary system?
Some people with symptomatic nephroptosis may experience a syndrome called Dietl crisis. In Dietl crisis, the floating kidney obstructs the ureter, the narrow tube leading from the kidney to the bladder. This can result in: violent flank pain.
What is the fibrous capsule of kidney?
renal capsule, thin membranous sheath that covers the outer surface of each kidney. The capsule is composed of tough fibres, chiefly collagen and elastin (fibrous proteins), that help to support the kidney mass and protect the vital tissue from injury.
Does perirenal fat cover the adrenal gland?
The perirenal fascia is a dense, elastic connective tissue sheath that envelops each kidney and adrenal gland together with a layer of surrounding perirenal fat forming the perirenal space.
Where is a Perinephric abscess?
Perinephric abscesses are located between the capsule of the kidney and the Gerota fascia. The abscesses remain confined in this location because of the Gerota fascia.
What is the importance of the renal fascia?
The renal fascia, commonly known as Gerota’s fascia, is a collagenous connective tissue sheath which separates the perirenal fat from the pararenal fat. It may be visualized radiographically and is helpful in the precise localization of abdominal masses.
What is the function of the medulla in the kidney?
The main function of the medulla is to regulate concentration of the urine. The urine flows from the collecting ducts into the renal calyces and pelvis, which undergoes unidirectional peristaltic movements to allow drainage of the urine into the downstream ureter and bladder.
What are the 4 main functions of a nephron?
The nephron uses four mechanisms to convert blood into urine: filtration, reabsorption, secretion, and excretion.
What is the importance of the perirenal and Pararenal fat?
Perirenal and pararenal fat capsules surround the kidneys and the thickness of these specific fat deposits is an independent predictor of chronic kidney disease in type-2 diabetes patients.
Is renal fascia same as renal capsule?
Externally, the kidneys are surrounded by three layers, illustrated in Figure 2. The outermost layer is a tough connective tissue layer called the renal fascia. The second layer is called the perirenal fat capsule, which helps anchor the kidneys in place. The third and innermost layer is the renal capsule.
What kidney is lower?
The right kidney usually is slightly lower than the left because the liver displaces it downward. The kidneys, protected by the lower ribs, lie in shallow depressions against the posterior abdominal wall and behind the parietal peritoneum.
What is the function of renal pelvis?
The area at the center of the kidney. Urine collects here and is funneled into the ureter, the tube that connects the kidney to the bladder.
What is Perirenal edema?
By chance, perirenal edema were discovered, and defined as high signal fluid spatters and rims surrounding the renal capsule in the perirenal fatty tissue around both kidneys (Fig. 2) in a thickness of 0.3–3.0 cm.
What is Perinephric fluid?
Perinephric fluid is a critical finding of ultrasonography in daily clinical practice. The condition includes a broad spectrum of diseases and the fluid may arise from the kidney or adjacent retroperitoneal structures. We present a case series of patients with perinephric fluid collection with ultrasound images.
Is Perinephric fat stranding serious?
While a degree of symmetric bilateral perinephric stranding is common, particularly in the elderly, asymmetric or unilateral perinephric stranding is an important sign of renal inflammation or of acute obstruction. As such, it is seen in conditions such as acute pyelonephritis and with ureteric calculi.
What is Fibrosis fat?
Like other fibrotic diseases, adipose tissue fibrosis is the accumulation and increased production of extracellular matrix (ECM) proteins. Adipose tissue fibrosis has been linked to decreased insulin sensitivity, poor bariatric surgery outcomes, and difficulty in weight loss.

What is the function of subcutaneous fat?
A layer of subcutaneous fat lies between the dermis and the underlying fascia. It helps to insulate the body from cold, cushions deep tissues from blunt trauma, and serves as a reserve source of energy for the body.
What causes forehead fat?
The reason behind excess face fat is poor diet, lack of exercise, aging, or genetic conditions. Check here the natural ways to get rid of face fat. Facial fat is caused by weight gain. The reason behind excess face fat is poor diet, lack of exercise, aging, or genetic conditions.
Does fat attach to skin?
The fat layer of skin is located in the subcutaneous layer of tissue called the hypodermis. The thickness of the fat layer, which varies greatly from one person to another, depends on the size and number of fat cells.
What is the difference between visceral fat and ectopic fat?
Hidden fat is known as visceral body fat – stored deep inside the abdomen – and ectopic fat, which accumulates in the liver, heart, pancreas and muscles.
What medications help with belly fat?
Meridia, Phentermine, and Xenical are the most commonly used FDA-approved drugs for treating obesity. They are used for people with a BMI of 30 and above, or those who have a BMI of 27 and other obesity-related medical conditions.
What are ectopic lipids?
Ectopic fat is defined by the deposition of triglycerides within cells of non-adipose tissue that normally contain only small amounts of fat. … However, fat mass and oxidative capacity influence this relationship, indicating that ectopic lipid content is not the only factor that explains insulin resistance.
What filters blood and removes waste?
The bean-shaped kidneys filter waste products out of the bloodstream and dispose of them by creating urine. Urine is made of these waste products dissolved in water.
What is a renal sinus?
The renal sinus is a central spacious cavity formed by the extension of the perinephric space into the deep recess located at the medial border of the kidney (,Figs 1, ,2). The renal sinus is surrounded by the kidney parenchyma laterally.
