When Drainage is Not Enough in Emphysematous Pyelonephritis Complicated by Necrotizing Fasciitis: A Case Report.

Necrotizing fasciitis (NF) is a rapidly progressive, life-threatening soft tissue infection characterized by widespread fascial necrosis, systemic toxicity, and high mortality without prompt surgical intervention. Emphysematous pyelonephritis (EPN) is a rare necrotizing infection of the kidney and perirenal tissues caused by gas-producing microbes, most often Escherichia coli, in patients with uncontrolled diabetes mellitus. We report the case of a 69-year-old man who developed NF with contiguous EPN. Despite aggressive surgical and medical management, he rapidly progressed to refractory septic shock and multi-organ failure, ultimately resulting in death. This case highlights the importance of early recognition of NF and determining its underlying cause, as delays in intervention may lead to uncontrollable sepsis.
