Several factors should be considered in renal atrophy

Renal atrophy usually left renal atrophy occurs , resulting in the formation of the main renal atrophy following reasons :
Renal atrophy and renal volume is based on the person's age , gender and body height and weight compared with each other . Shijiazhuang Kidney Disease Hospital has been advocating the use of B -mode ultrasound examination kidneys , it is the most simple and convenient , and economical. B -mode ultrasound method for measuring the size of the kidney including renal poles diameter and thickness of the renal parenchyma . Kidney diameter according to ethnicity, height, age and there are some differences , the left kidney slightly longer than the right kidney , males slightly larger than females. Adult renal parenchymal thickness of about 1.5 ~ 2cm, no significant differences in the elderly , <1.5cm to narrow ,> 2.0cm is thickened. Generally kidney diameter plus parenchymal thickness measurements to identify acute and chronic renal failure , in line with rate of 92.6%. Suffering from chronic kidney disease , kidney size measured regularly , can help monitor disease progression .
First to be considered that renal atrophy congenital renal hypoplasia , followed by consideration of end-stage renal disease, ie renal failure, uremia , or some acute illness. Such as: acute renal disease, diabetes, renal cirrhosis , kidney transplant rejection , chronic glomerulonephritis, renal cortical necrosis , Alport syndrome, acute tubular necrosis , hypertensive nephrosclerosis .
Bilateral renal or kidney narrow side more than the cause of chronic pyelonephritis , which is also a common cause of renal atrophy .
Generally the development of chronic kidney disease kidneys shrink to renal insufficiency, especially renal failure, uremia , serum creatinine, blood urea nitrogen increased, serious kidney damage, renal parenchymal injury , kidney will be reduced . So be sure to remind patients of renal atrophy great attention to this , a strong occult renal disease , if the glomerular filtration rate below 50 %, that is a serious clinical symptoms of kidney damage was consequential . Renal atrophy after diagnosis must actively find reasons to troubleshoot the condition.

In addition, renal atrophy reason there are two things : renal tuberculosis ( unilateral renal narrow , with contralateral hydronephrosis or compensatory increase ) , renal artery stenosis and congenital hypoplasia.
