The renal fascia was originally described as consisting of two distinct structures: the anterior renal fascia (Gerota's fascia), and posterior renal fascia (Zuckerkandl's fascia); these two fasciae were said to fuse laterally to form the lateroconal fascia. Understanding of the structure of the renal fascia has subsequently evolved. [1]
The renal capsule is surrounded by the renal fascia. Overlying the renal fascia and between this and the transverse fascia is a region of pararenal fat. [1] The renal capsule resists stretching, limiting renal swelling, with important implications for renal circulation. [2] Stretching of the renal capsule due to swelling of the kidney causes ...
Renal hematoma locations with corresponding renal anatomy. Each kidney is surrounded by two layers of connective tissue, the inner renal capsule and outer renal (Gerota's) fascia. [7] These layers thus form two potential spaces where fluid can form, the small subcapsular space and the large perinephric space.
Each kidney, with its adrenal gland is surrounded by two layers of fat: the perirenal fat present between renal fascia and renal capsule and pararenal fat superior to the renal fascia. The human kidney is a bean-shaped structure with a convex and a concave border. [ 14 ]
Gerota researched the anatomy and physiology of the bladder and appendix, and developed a method for injecting lymphatic vessels known in textbooks as the "Gerota method". The renal fascia is sometimes called Gerota's fascia or Gerota's capsule after him. Also, the Albarran-Ormond syndrome (an inflammatory retroperitoneal fibrosis, named after ...
From anterior to posterior, the renal vein exits, the renal artery enters, and the renal pelvis exits the kidney. On the left hand side the hilum is located at the L1 vertebral level and the right kidney at level L1-2. The lower border of the kidneys is usually alongside L3.
The collecting duct system is the final component of the kidney to influence the body's electrolyte and fluid balance. In humans, the system accounts for 4–5% of the kidney's reabsorption of sodium and 5% of the kidney's reabsorption of water. At times of extreme dehydration, over 24% of the filtered water may be reabsorbed in the collecting ...
The glomerular basement membrane of the kidney is the basal lamina layer of the glomerulus.The glomerular endothelial cells, the glomerular basement membrane, and the filtration slits between the podocytes perform the filtration function of the glomerulus, separating the blood in the capillaries from the filtrate that forms in Bowman's capsule.
