Your kidneys are two bean-shaped organs about the size of your fist. Red-brown in color, they are located on either side of your spine in your upper abdomen. They are part of the urinary tract, and filter waste products, excess salt, and fluids out of the blood. These waste products are then excreted as urine.

Chronic and acute renal failure stem from different root causes. While acute renal failure is more likely to develop due to sudden injury, infection or rapidly developing medical conditions, chronic renal insufficiency tends to result from gradual damage caused by diabetes, cancer, or hypertension (high blood pressure).
Causes of Acute Renal Failure
Three separate types of acute renal failure (ARF) have been... Read more >
Kidney cysts are not common, but left untreated, they can cause damage that leads to eventual renal failure. Kidney cysts are usually caused by inherited genetic disorders. They require lifelong treatment: Cures for the disorders are currently unavailable.
