Your kidneys are 2 bean-shaped organs about the size of a fist, located near the middle of the back, below the rib cage. Kidneys filter blood by keeping compounds that are useful and removing waste and excess fluid, and they help regulate blood pressure and the number of red blood cells. Every 30 minutes, your kidneys filter all the blood in your body. The February 11, 2009, issue of JAMA includes an article about dietary phosphorus intake among patients with end-stage kidney disease. This Patient Page is based on one published in the December 12, 2001, issue of JAMA.

TYPES OF KIDNEY FAILURE

Kidney failure occurs when the kidneys cannot properly remove wastes, causing buildup of waste and fluid in the body. By checking blood and urine tests, your doctor can determine if you have kidney failure.

  • Acute kidney failure develops suddenly, sometimes because of severe infection, drugs or other chemical agents, or physical trauma. If the underlying problem can be successfully treated, complete recovery of the kidneys is possible.

  • Chronic kidney failure develops gradually over years and may cause weight loss, anemia (low blood cell count), nausea or vomiting, tiredness, headaches, decreased mental sharpness, muscle twitches and cramps, yellowish-brown skin color, unusual itching, and trouble sleeping.

  • End-stage kidney disease causes anemia, high blood pressure, bone disease, heart failure, and poor mental functioning.

TREATING KIDNEY FAILURE

  • Dialysis is the treatment used when the kidneys stop working altogether. In hemodialysis, blood is sent through a machine that filters away the waste products and returns the clean blood to the body. In peritoneal dialysis a fluid called dialysate is introduced into the abdomen; it captures waste products from the blood and is drained away.

  • Transplantation is the use of a new kidney from a donor to replace damaged kidneys. Transplants involve major surgery and usually require treatment to prevent rejection of the new organ.

See a doctor if you have pain or burning when you urinate, frequent urges to urinate, urine that is cloudy or dark, fever or a feeling of shakiness, or pain in your back or side below your ribs that does not go away. Treatment of high blood pressure and diabetes can help prevent kidney disease.
