Whether the size of adult left kidney 8.55*5.01cm is serious or not needs to be clarified for its etiology, and cannot be generalized. If the left kidney is small due to congenital causes, it is usually not serious if the renal function is normal; if the left kidney is shrunken due to pathological causes such as chronic kidney disease, with the development of the disease, it may progress to uremia, which is more serious at this time.
Generally speaking, the length, width and thickness of Chinese adult kidney are 10.5~11.5cm, 5~7.2cm and 2~3cm respectively, therefore, the left kidney of adult 8.55*5.01cm suggests that the left kidney is shrunken. If the left kidney is shrunken due to congenital factors, at this time, if the renal function is normal, there is no need for special treatment and it is usually not serious.
Small kidneys may also be caused by renal atrophy due to chronic kidney diseases, such as chronic renal failure, double renal artery stenosis, etc. All of them may cause kidney size reduction, which may lead to renal function decline and develop into uremia in serious cases if they are not detected in time and effectively treated. This situation is more serious.
If patients find that the size of the kidneys is shrinking, it is recommended to go to regular hospitals in a timely manner, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
