Renal tubular acidosis

A condition in which the kidneys are unable to excrete normal amounts of acid made by the body. The blood is more acidic than normal, and the urine less acidic. Causes include kidney damage due to disease, drugs, or a genetic disorder; but in many cases the cause is unknown. The acidosis may result in osteomalacia, kidney stones (see calculus, urinary tract), nephrocalcinosis, and hypokalaemia (an abnormally low level of potassium in the blood).
