Kidney Failure Vs. Renal Failure

by Kristin A. Ricca
  • Overview

    Kidney failure, also known as renal failure, can be acute or chronic and occurs when your kidneys do not filter properly, resulting in a buildup of harmful materials in your body.
  • Identification

    The kidneys eliminate excess fluid, electrolytes and waste material from your blood. If your kidneys are unable to filter, your body collects dangerous levels of fluid, electrolytes and waste resulting in acute or chronic kidney failure.
  • Acute

    According to MayoClinic.com, acute kidney failure is the sudden loss of the kidneys' ability to perform their filtering function. You may be able to recover normal kidney function if you are in good health.
  • Chronic

    Chronic kidney failure occurs over a period of time and has no cure. You may not experience any symptoms until kidney function has decreased to 25 percent or less.
  • Causes

    Acute kidney failure is caused by prerenal conditions disrupting blood flow to the kidneys, renal conditions damaging the kidneys and postrenal conditions impacting the removal of waste. Diabetes, hypertension, obstruction of urine flow, kidney diseases, renal artery stenosis and toxins cause chronic kidney disease.
  • Treatment

    In acute kidney failure, the underlying condition damaging the kidneys is treated, followed possibly by a special diet, medications and temporary dialysis. To delay the progression of chronic kidney failure to end-stage kidney disease, the underlying conditions are treated followed by special diet, medications, dialysis or transplant.
