Emphysematous pyelonephritis (EPN) is an uncommon but necrotizing renal infection due to gas-forming coliform bacteria that usually occurs in patients with diabetes mellitus and/or obstructive uropathy. Bilateral EPN is rarely seen and recurrent infection in different kidneys has never been reported in the literature. Here we present a female diabetic patient who experienced two episodes of EPN in different kidneys within 2.5 years, resulting in death eventually. We discuss the pathogenesis, incompatibility between clinical features and radiological findings of EPN, and the principle of management for this life-threatening infection.
气肿性肾盂肾炎（EPN）是一种罕见的坏死性肾脏感染，由产气大肠菌引起，通常发生于糖尿病和/或梗阻性尿路病患者。双侧EPN罕见，文献中从未报道过不同肾脏的反复感染。本文报告一名女性糖尿病患者，在2.5年内不同肾脏发生两次EPN发作，最终导致死亡。我们讨论了EPN的发病机制、临床特征与影像学表现之间的不一致性，以及这种危及生命感染的治疗原则。
