Renal Necrosis

Renal necrosis is a kidney disease in which some or more of the papillae die. Renal papillae are the places in which the accumulating duct openings reach the kidney and urine flows into the ureters. Renal cortical necrosis is a rare cause of acute necrosis usually due to severely decreased renal arterial flow due to acute necrosis of the tubules. The condition is caused by significantly decreased kidney arterial perfusion due to feeding artery spasms, microvascular injury, or disseminated intravascular coagulation, and is the progression of acute tubular necrosis pathology.
