Renal papillary necrosis

Summary of Renal papillary necrosis
Renal papillary necrosis is a nephropathy resulting from impaired blood supply leading to diffuse necrosis of the renal papilla. Lesions that characterize renal papillary necrosis come from an impairment of the blood supply and from subsequent ischemic necrosis that is diffuse. The pathophysiology of this condition can be due to analgesic nephropathy, which in turn is a result of long-term use of aspirin.
