Dent's disease (or Dent disease) is a rare X-linked recessive inherited condition that affects the proximal renal tubules [1] of the kidney.It is one cause of Fanconi syndrome, and is characterized by tubular proteinuria, excess calcium in the urine, formation of calcium kidney stones, nephrocalcinosis, and chronic kidney failure.
Joint contractures of the fingers, elbows and knees can develop secondary to skin involvement and can severely impair physical function. [6] [8] While skin involvement is on the foreground, the process may involve any organ, e.g., the eye, [8] heart, diaphragm, pleura, pericardium, and kidneys, [6] [9] as well as the lungs and liver.

All structures of the kidney can show ischemic atrophy although glomerular ischemic atrophy may be patchy. [1] In advanced cases of benign nephrosclerosis the glomerular tufts may become globally sclerosed. Diffuse tubular atrophy and interstitial fibrosis are present. Often there is a scant interstitial lymphocytic infiltrate.
Angiomyolipoma seen as a hyperechoic mass in the upper pole of an adult kidney on renal ultrasonography. Renal ultrasonography of a person with tuberous sclerosis and multiple angiomyolipomas in the kidney: Measurement of kidney length on the US image is illustrated by '+' and a dashed line. CT scan of a renal angiomyolipoma.
Minimal change disease (MCD), also known as lipoid nephrosis or nil disease, among others, is a disease affecting the kidneys which causes nephrotic syndrome. [1] Nephrotic syndrome leads to the loss of significant amounts of protein to the urine (proteinuria), which causes the widespread edema (soft tissue swelling) and impaired kidney function commonly experienced by those affected by the ...
This illustration demonstrates the normal kidney physiology, including the Proximal Convoluted Tubule (PCT), Loop of Henle, and Distal Convoluted Tubule (DCT). It also includes illustrations showing where some types of diuretics act, and what they do. Renal physiology (Latin renes, "kidneys") is the study of the physiology of the kidney.
While not present at birth, kidney problems develop in many affected boys at about one year of age. [1] Renal pathology is characterized by an abnormal loss of certain substances into the urine, including bicarbonate, sodium, potassium, amino acids, organic acids, albumin, calcium and L-carnitine. This problem is known as Fanconi-type renal ...
Uremic pruritus is defined as itching that is directly caused by chronic kidney disease, with no other explainable conditions. [14] Uremic pruritus cannot be diagnosed with laboratory tests or established criteria because of its variability and lack of specific skin lesions.
