Kidney failure, also called renal failure, can happen as a result of slow blood flow to the kidneys, direct injury to the kidneys or though the blockage of the kidney's urine drainage tubes, according to the Mayo Clinic. Kidney failure usually occurs in connection with another medical condition or event that directly affects kidney function.

Symptoms of kidney disease often do not manifest until the late stages of the disease, warns the National Kidney Foundation. For this reason, people are sometimes unaware of the disease until their kidneys fail. Early detection of chronic kidney disease can help prevent it from progressing to kidney failure.

Healthy kidneys clean the blood of waste products and extra water, make red blood cells and help control blood pressure, explains the National Kidney Foundation. When the kidneys fail, approximately 85 to 90 percent of kidney function is gone, and the kidneys are unable to maintain their life-sustaining role. While kidney failure has no cure, it is treatable through dialysis or a kidney transplant. Both treatments take over the role of removing wastes and extra fluids from the body.
