Acute renal cortical necrosis in a series of young men with severe acute pancreatitis

Diffuse renal cortical necrosis from any cause is rare in the Western World. Over the last 5 decades, there have been isolated case reports of acute cortical necrosis as a consequence of acute pancreatitis, but the long-term outcome of these patients has not previously been reported. Here, we report 3 young men, aged 16-21 years, who have presented over the past 19 years with severe acute pancreatitis associated with oliguric acute renal failure. They were all found to have diffuse renal cortical necrosis and consequently made no renal recovery. Despite the appreciable mortality associated with acute pancreatitis complicated by acute renal failure, they all survived the initial illness and all have successfully undergone renal transplantation. We present a detailed account of each patient including diagnostic strategies and discuss the possible factors contributing to a favorable outcome in these patients.
