Renal failure— Is a condition in which the kidneys as a result of any disease no longer do their job in a sufficient amount for the body. This leads to disruption constant throughout the internal environment, which leads to malfunction of organs and tissues.
Renal failure may be acute or chronic.
In acute renal failure (ARF), the kidneys quickly disrupted due to heavy volume and destruction of renal tissue. The reasons for such lesions can be both in the kidney (cell death under the influence of poisons, alcohol substitutes, drugs, acute inflammation, or lack of blood supply), and outside of it (heart failure, massive blood loss, bilateral ureteral obstruction, etc.). Fortunately, this process is often reversible.
Chronic kidney failure (ESRD) occurs when slowly progressive kidney disease, when the amount of working kidney tissue decreases gradually and is usually irreversible. Lead to this inflammatory (more often — glomerulonephritis), exchange, system, neoplastic, vascular, and hereditary diseases. As a result of this impaired water excretion and metabolism products, leading to a gradual self-poisoning organism products of nitrogen metabolism, increases the load on the heart and blood vessels due to the increased volume of fluid is a variety of other disorders in the organism.
In the initial stages of CKD process can be monitored using an appropriate diet and medication. As the disease patients require regular hemodialysis using the apparatus of the "artificial kidney", And ideally they should be transplanted kidney.
