Causes of unilateral renal atrophy

admin TAGS: 2017-08-11 17:33

The common renal atrophy is in addition to all kinds of polycystic kidney of chronic kidney disease to chronic renal failure and end-stage renal disease are common symptoms of uremia, such as diabetic nephropathy, hypertensive nephropathy, Henoch Schonlein purpura nephritis, lupus nephritis, chronic pyelonephritis, primary chronic nephritis to chronic renal failure, or acute kidney the legacy of the injury in chronic renal failure and so on. Their common features are the atrophy of both kidneys, the thinning of cortex and the decrease of renal function. When polycystic kidney develops into chronic renal failure, because of the large number of vesicles, the surface volume shows the enlargement of the kidney, but in fact the functional renal parenchyma is markedly reduced. It can be found that all systemic diseases or chronic nephritis of the primary kidney develop into chronic renal failure, and both of them are bilateral atrophy. However, some unilateral kidney diseases cause atrophy of the kidney, which is unilateral, that is, the renal side of the renal disease is atrophic:
Congenital unilateral renal agenesis: This is in the mold development process from one side kidney disorder, even when the ultrasound is born blank side kidney is small, undeveloped, often to adulthood was discovered. Because of the relatively long time, the normal developing kidney of the contralateral side is gradually compensated, so the contralateral healthy kidney is compensatory.
Atherosclerosis: systemic atherosclerosis can lead to arterial stenosis in important organs, such as coronary atherosclerotic heart disease and atherosclerotic atherosclerotic kidney stenosis. While atherosclerotic renal stenosis leads to ischemic kidney disease, one side of the kidney has a long duration of ischemia and will atrophy, function down or even lose. If both sides of the renal artery have atherosclerotic stenosis, depending on the degree of stenosis of each side of the artery, both sides of the kidney may atrophy in varying degrees.
Takayasu arteritis is an autoimmune disease that can cause unilateral renal artery stenosis and atrophy of the blood supply to the kidneys.
Kidney, ureter stone or the kidney seeper that causes all sorts of reasons, when cannot dredge for a long time, the kidney becomes thin and atrophic gradually below high pressure.
Repeated episodes of pyelonephritis can cause one side of the kidney to become progressively fibrotic and atrophy. Renal tuberculosis is a kind of special renal infection, usually unilateral renal tuberculosis, tuberculous abscess in the cortex, caseous necrosis, resulting in tuberculosis, kidney destruction, fibrosis, and often accompanied by calcification and abscess or hydronephrosis.
Surgical treatment of one side of the kidney can also cause atrophy of the kidney due to damage to the blood vessels of the kidneys. One side of the kidney is subjected to repeated extracorporeal shock wave lithotripsy, and a few years later, one side of the kidney may be found to atrophy. After one side of the kidney trauma and blood vessels, the one side of the kidney cortex will atrophy.
