Chronic renal failure represents a slow decline in kidney function over time. Chronic renal failure may be caused by a number of disorders, which include long-standing hypertension, diabetes, congestive heart failure, lupus or sickle cell anemia. If renal function declines to a low enough level (end-stage renal disease) kidney dialysis may be necessary. A sudden decline in renal function may be triggered by a number of acute disease processes.
means that your kidneys are declining in their functioning. The word chronic means that it is long standing condition. Kidney functioning is generally low.
Damage to the kidneys that cannot be reversed, usually progressive in nature.
Slow and progressive loss of kidney function over several years, often resulting in end-stage renal disease. People with end-stage renal disease need dialysis or transplantation to replace the work of the kidneys.
The slow and progressive deterioration of kidney function. Initially, there may be little to see or find, and this means that many patients present for medical help very late in their disease.
Kidney failure that takes place over a long period of time. Chronic renal failure is usually not reversible.
a slow and progressive loss of kidney function over several years, often resulting in total kidney failure or ESRD.
An irreversible condition in which the kidneys function at about one-quarter or less than normal level.
Slow progressive loss of kidney function over the span of years, resulting in permanent kidney failure. Chronic kidney disease is common and may go undiagnosed until the process is far advanced and renal failure is on the horizon. People with permanent kidney failure need dialysis or a transplanted kidney to do the work of their failed kidneys. See the entire definition of Chronic renal failure
(CRF) Irreversible, progressive impaired kidney function. The early stage, when the kidneys no longer function properly but do not yet require dialysis, is known as Chronic Renal Insufficiency (CRI). CRI can be difficult to diagnose, as symptoms are not usually apparent until kidney disease has progressed significantly. Common symptoms include a frequent need to urinate and swelling, as well as possible anemia, fatigue, weakness, headaches and loss of appetite. As the disease progresses, other symptoms such as nausea, vomiting, bad breath and itchy skin may develop as toxic metabolites, normally filtered out of the blood by the kidneys, build up to harmful levels. Over time (up to 10 or 20 years), CRF generally progresses from CRI to End-Stage Renal Disease (ESRD, also known as Kidney Failure). Patients with ESRD no longer have kidney function adequate to sustain life and require dialysis or kidney transplantation. Without proper treatment, ESRD is fatal.
Chronic renal failure (CRF, or "chronic kidney failure", CKF, or "chronic kidney disease", CKD) is a slowly progressive loss of renal function over a period of months or years and defined as an abnormally low glomerular filtration rate, which is usually determined indirectly by the creatinine level in blood serum.
