renal papillary necrosis

Destruction of the papillae of the kidney, usually as a result of pyelonephritis, diabetes mellitus, sickle cell disease, urinary obstruction, or the toxic effects of nonsteroidal anti-inflammatory drugs. If the necrotic tissue sloughs into the ureters, it may cause renal colic similar to the pain caused by a kidney stone.
