What is the renal sinus fat?
Renal sinus fat (RSF) is a perivascular fat compartment located around renal arteries. In this in vitro and in vivo study we hypothesized that the hepatokine fetuin-A may impair renal function in non alcoholic fatty liver disease (NAFLD) by altering inflammatory signalling in RSF.
What is the function of the fat around the kidney?
The accumulation of renal sinus fat is important because the renal vein and artery pass through the renal sinus and may be compressed by ectopic fat. Renal vein constriction has been shown to increase kidney volume and renal interstitial pressure and decrease sodium excretion in animal models.
Why is the renal sinus important?
The observation of renal sinus fat is important for detecting a small tumor located in that area and determining the exact tumor stage. Multiplanar CT or MR images can allow exact evaluation of the extent of complex renal sinus disease.
Is renal sinus hyperechoic?
The renal sinus is hyperechoic and is composed of calyces, the renal pelvis, fat and the major intrarenal vessels. In the normal kidney, the urinary collecting system in the renal sinus is not visible, but it creates a heteroechoic appearance with the interposed fat and vessels.
What are renal sinus cysts?
Renal sinus cysts (sometimes referred to as peripelvic cysts) are asymptomatic cysts that arise from the lymphatics of the renal hilum. Peripelvic renal cysts defined as cysts which are situated in the renal hilus, intimately related with the renal pelvis and calyces.
What structures are located in the renal sinus?
The kidney parenchyma surrounds the centrally located, hyperechoic fatty renal sinus, which contains the renal pelvis, calyces, major branches of the renal artery and vein, and lymphatic vessels.
How can I reduce fat around my kidneys?
If you are suffering from kidney problems, make sure that you consume enough potassium and phosphorus. Try to exercise for 30 minutes every day, no matter how busy you are. Include light weight training in your workout routine for losing extra fat from the body.
Does the kidney metabolize fat?
The kidney is usually not regarded as an important organ in lipid metabolism because the glomerular filtration barrier prevents large molecules such as lipoprotein particles from being filtered into the pre-urine.
What is Pelvicalyceal system?
It means the part of kidney draining urine to ureter(connecting tube between kidney and urinary bladder)is dilated..it may be a temporary dilation or due to some obstruction of urine flow Read More.
What is the difference between renal pelvis and renal sinus?
The cortex and medulla make up the parenchyma, or functional tissue, of the kidney. The central region of the kidney contains the renal pelvis, which is located in the renal sinus, and is continuous with the ureter. The renal pelvis is a large cavity that collects the urine as it is produced.
What is found within the renal sinus?
The renal sinus is a cavity within the kidney which is occupied by the renal pelvis, renal calyces, blood vessels, nerves and fat. The renal hilum extends into a large cavity within the kidney occupied by the renal vessels, minor renal calyces, major renal calyces, renal pelvis and some adipose tissue.
Where is the renal sinus located?
the kidney
The renal sinus is a fatty compartment located within the medial aspect of the kidney. It communicates with the perinephric space. It contains the renal hilum and is bordered by renal parenchyma laterally.
Where is sinus fat found in the kidney?
can be found involving the renal sinus, either aris- ing primarily from sinus structures or secondarily extending into the sinus from the adjacent cortex or retroperitoneum. Observation of renal sinus fat is important in detecting a small tumor and deter-
Why is renal sinus fat important in the evaluation of sinus cancer?
The observation of renal sinus fat is important for detecting a small tumor located in that area and deter- mining the exact tumor stage. Multiplanar CT or MR images can allow exact evaluation of the extent of complex renal sinus disease. ©RSNA, 2004
What is the meaning of renal sinus?
Definition of Renal Sinus. What is renal sinus? It is simply a cavity in the kidney that serves as the expansion behind the renal calyxes, renal pelvis, nerves, blood vessels and fat. Symptoms of renal sinus infection include lower back pain, urinary urgency, excessive excretion of pus or blood and fever.
What is the renal sinus made of?
Introduction 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 sur- rounded by the kidney parenchyma laterally.
