Renal atrophy is according to the kidney volume and the person’s age 、gender and body height and weight in comparison to each other .Generally speaking , when chronic kidney disease develop into renal insufficiency especially kidney failure 、uremia ,the serum creatinine 、urea nitrogen will rise ,the kidney injury serious , renal parenchymal will get damaged ,kidney will shrink .The normal size of kidney (major axis): The left side is 11-1305cm(an average of 12.2cm),the right side is 10.8-13cm(an average of 11.9cm),which is equal to three adjacent lumbar body including the sum of the intervertebral disc half of the width to length .
Adult renal parenchyma thickness is about 1.5-2 .0cm ,the elderly also have no obvious difference ,2.0 cm belong to thickening .According to the survey with renal length to diameter and thickness measurement of renal parenchyma identify acute and chronic renal failure ,coincidence rate was 92.6%.Regular check the renal size can contribute to observe progress lesion for patients with chronic kidney disease .
1.Patients with renal atrophy should give up smoking and drinking ,and have a good rest .
2.If it is the unilateral renal atrophy ,patients can consider excision .
3.The increased creatinine can solve through dialysis ,control the intake of protein .
4.There are a lot of reasons of causing renal atrophy ,including various system disease factors such as all kinds of kidney diseases 、reno-vascular disease 、kidney injury cannot get effective treatment will cause renal atrophy .The development of all kinds of kidney disease is kidney fibrosis ,will show kidney shrink in the end ,so can take anti-fibrosis treatment when curing renal atrophy .
