Summary
Renal papillary necrosis is a condition in which impaired blood supply to the kidneys leads to diffuse ischemia and subsequent necrosis of the renal papilla. Risk factors for renal papillary necrosis include diabetes, sickle cell anemia, and certain medications such as non-steroidal anti-inflammatory drugs (NSAIDs). Symptoms may include fever, flank pain, and blood in the urine. Treatment may include antibiotics, pain management, and in severe cases, surgery.
