As we all know ,renal atrophy is according to the kidney volume and compares to a person’s age 、gender 、height and weight ,which is relatively small or obviously narrowed .So what kinds of factors that cause renal atrophy ?
1.When patients get the renal atrophy should first consider for congenital kidney dystrophia and then should consider for end-stage kidney disease ,that is kidney failure 、uremia or some acute kidney diseases ,such as acute glomerular disease 、diabetic nephrosclerosis 、renal transplant rejection 、chronic glomerulonephritis 、renal cortical necrosis 、Alport syndrome 、acute tubular necrosis 、hypertensive nephrosclerosis .
2.Generally speaking ,when the chronic kidney disease develop into renal insufficiency ,especially renal failure 、uremia ,the serum creatinine 、urea nitrogen rise ,serious kidney damage ,renal parenchymal damaged ,the kidney will shrink .So patients with renal atrophy should pay more attention to this disease ,because the kidney disease with strong occult ,if the glomerular filtration rate is less than 50% ,that is when the renal lesion is serious will have the clinical symptoms .After diagnosing the renal atrophy must find the reasons so as to treat the illness as soon as possible .
3.One side kidney or double kidneys shrink most are the reasons of causing chronic pyelonephritis ,which is the common reasons of renal atrophy .
4.In addition ,there are two factors of causing renal atrophy :renal tuberculosis (unilateral kidney shrink and accompany with the contralateral kidney seeper or compensatory increase )、renal artery stenosis and congenital aplasia .
