Acute renal failure develops rapidly, usually in less than a few days. It is most common in people who are already hospitalized, especially in critically ill condition, who need intensive treatment. Acute renal failure can be fatal and requires prompt and timely action. Often this process is reversible. Good physical health is essential to restore normal or near-normal kidney function.
Acute renal failure is very severe and is a dramatic condition in which the kidneys suddenly stop producing urine and the patient stops urinating. This can be a consequence of various diseases and injuries – severe acute kidney disease, major blood loss, severe shock injuries, dehydration (incessant vomiting and diarrhea), severe infections and more. An acute renal failure that lasts more than three months turns into a chronic one.
With the chronic renal failure there is a gradual and irreversible failure of the kidney function. Many are the diseases that may cause herein including: a hypertension disease, a diabetes, chronic diseases of glmerulus and kidney infections, gout, renal-stone disease, tissue and congenital malformations in the kidney structure. There are medicines that may also cause irreversible kidney damage.
Unlike acute renal failure, chronic renal failure sometimes occurs covertly and unnoticed. To control these processes, a urine test should be performed 1-2 times a year, even if there are no complaints. A signal to suspect kidney disease is the presence of albumin in the urine and possible blood cells (leukocytes). In these situations, timely consultation with a specialist is mandatory.
