- A disorder characterized by gradual and usually permanent loss of kidney function resulting in renal failure.
- A neoplastic or non-neoplastic condition affecting the kidney. Representative examples of non-neoplastic conditions include glomerulonephritis and nephrotic syndrome. Representative examples of neoplastic conditions include benign processes (e.g., renal lipoma and renal fibroma) and malignant processes (e.g., renal cell carcinoma and renal lymphoma).
- A term referring to any disease affecting the kidneys.
- An irreversible and usually progressive reduction in renal function in which both kidneys have been damaged by a variety of diseases to the extent that they are unable to adequately remove the metabolic products from the blood and regulate the body's electrolyte composition and acid-base balance. (from msh98)
- Chronic, irreversible renal failure.
- Gradual and usually permanent loss of kidney function resulting in renal failure. Causes include diabetes, hypertension, and glomerulonephritis.
- Impairment of health or a condition of abnormal functioning of the kidney.
- Impairment of the renal function due to chronic kidney damage.
- Irreversible and usually progressive reduction in renal function in which both kidneys have been damaged by a variety of diseases to the extent that they are unable to adequately remove the metabolic products from the blood and regulate the body's electrolyte composition and acid-base balance.
- Pathological processes of the kidney or its component tissues.
- The end-stage of chronic renal insufficiency. It is characterized by the severe irreversible kidney damage (as measured by the level of proteinuria) and the reduction in glomerular filtration rate to less than 15 ml per min (kidney foundation: kidney disease outcome quality initiative, 2002). These patients generally require hemodialysis or kidney transplantation.
- You have two kidneys, each about the size of your fist. Their main job is to filter wastes and excess water out of your blood to make urine. They also keep the body's chemical balance, help control blood pressure, and make hormones.chronic kidney disease (ckd) means that your kidneys are damaged and can't filter blood as they should. This damage can cause wastes to build up in your body. It can also cause other problems that can harm your health. Diabetes and high blood pressure are the most common causes of ckd.treatment may include medicines to lower blood pressure, control blood glucose, and lower blood cholesterol. Ckd can get worse over time. Ckd may lead to kidney failure. The only treatment options for kidney failure are dialysis or a kidney transplantation.you can take steps to keep your kidneys healthier longer:
- choose foods with less salt (sodium)
- keep your blood pressure below 130/80
- keep your blood glucose in the target range, if you have diabetes
- Your kidneys are two bean-shaped organs, each about the size of your fists. They are located near the middle of your back, just below the rib cage. Inside each kidney about a million tiny structures called nephrons filter blood. They remove waste products and extra water, which become urine. The urine flows through tubes called ureters to your bladder, which stores the urine until you go to the bathroom. Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines. You are at greater risk for kidney disease if you have diabetes, high blood pressure, or a close family member with kidney disease. chronic kidney disease damages the nephrons slowly over several years. Other kidney problems include:
- cancer
- cysts
- stones
- infections
