Acute kidney injury favors elderly

The high risk group of acute kidney injury refers to the existence of certain factors, compared with the general population, the risk of acute kidney injury is extremely high. The first is the decline of the body function of the elderly. Patients with renal failure, the service center, said: "with the growth of the elderly, the size of the kidney, kidney reserve decreased, more likely to suffer from acute kidney injury."

The kidney is responsible for maintaining the stability of the human body environment, excretion of excess water and metabolic waste. According to the director of bovine heart, the basic unit of the structure and function of the kidney is a renal unit, each of which consists of about 1 million units. Since the age of 40, the number of renal function unit gradually reduced, approximately every 10 years and the kidney volume naturally reduced weight 10%; decrease of renal blood flow, every 10 years fell about 10%; glomerular filtration function also decreased year by year, about 8% every 10 years of decline.

"The kidney of the elderly to stimulate the external stress and the ability to compensate for the decline, coupled with a variety of other diseases, often doomed to the elderly belong to the high risk of acute kidney injury." Renal failure patient service center.

Patients with post renal factors, such as hypertrophy of the prostate and bladder contraction, lead to poor urination.

The service center for patients with renal failure suggest that ordinary people at least once a year the urine test, a simple urine routine examination need only a few dollars, provide useful clues for diagnosis of kidney disease can be found as soon as possible, for the existing basis of kidney disease, timely correction and removal of risk factors to provide help. As for the high-risk groups of acute kidney injury, vigilance, feeling unwell early medical treatment, according to the specific circumstances at any time, as appropriate, the detection of urine routine, renal function and renal B ultrasound.
