In neonates and children up to six months of age, the cortex is more echogenic than the liver and spleen when compared at the same depth. [1] Doppler ultrasonography of the kidney is widely used, and the vessels are easily depicted by the color Doppler technique in order to evaluate perfusion. Applying spectral Doppler to the renal artery and ...
Parenchymal destruction: The renal tissue undergoes caseous necrosis, fibrosis, and calcification. Fibrosis and shrinkage : Progressive scarring results in a small, irregularly shaped kidney. Calcification : Deposition of calcium salts within the necrotic tissue leads to the characteristic dense appearance of the kidney on imaging.
It may cause acute kidney injury. It is now more commonly used to describe diffuse, fine, renal parenchymal calcification in radiology. [2] It is caused by multiple different conditions and is determined by progressive kidney dysfunction. These outlines eventually come together to form a dense mass. [3]
The parenchymal cells include myocytes, and many types of specialised cells. The cells are often attached to each other and also to their nearby epithelial cells mainly by gap junctions and hemidesmosomes. There is much variation in the types of cell in the parenchyma according to the species and anatomical regions.
An estimate of the GFR is used clinically to determine the degree of kidney impairment and to track the progression of the disease. The GFR, however, does not reveal the source of the kidney disease. This is accomplished by urinalysis, measurement of urine protein excretion, kidney imaging, and, if necessary, kidney biopsy. [1]
Pyonephrosis (from Greek pyon 'pus' and nephros 'kidney' [1]) is a dangerous kidney infection that is characterized by pus accumulation in the renal collecting system. [2] It is linked to renal collecting system blockage and suppurative renal parenchymal destruction, which result in complete or nearly complete kidney failure. [3]
Since Page kidney is a unilateral process, symptom presentation differs significantly depending on if patients have native kidneys or only one functioning kidney, such as renal transplant recipients. [2] In those with a normally functioning second kidney, the only symptom may be new-onset hypertension.
The right kidney sits just below the diaphragm and posterior to the liver. The left kidney sits below the diaphragm and posterior to the spleen. On top of each kidney is an adrenal gland. The upper parts of the kidneys are partially protected by the 11th and 12th ribs.
