When blood flow in the arteries supplying the kidneys is completely blocked, the entire kidney or a portion of the kidney supplied by that artery dies (kidney infarction). Kidney infarction can lead to the inability of the kidneys to process and excrete the body's waste products (kidney failure). Blood vessel disorders of the kidneys have a number of causes, including blockages in the renal arteries or veins, inflammation of blood vessels , injury to the kidneys or blood vessels, and other disorders.
