Emphysematous pyelonephritis (EPN) is a rare and life-threatening sequalae of a urinary tract infection marked by a gas-producing necrotizing infection of the renal parenchyma requiring prompt treatment. It has been found to be correlated with uncontrolled diabetes mellitus and is more common in females due to their increased susceptibility to urinary tract infections. Early recognition and treatment of EPN are essential to improve the patient's prognosis and prevent further complications. In this case we highlight a progressive case of pyelonephritis complicated by emphysematous abscess formation requiring surgical management. A 49-year-old female with a history of diabetes, hypertension, asthma, and lupus who presented to the emergency department (ED) for evaluation of generalized weakness. Lactate was elevated and urinalysis was suggestive of infection. A computed tomography (CT) scan of the abdomen and pelvis revealed a large subcapsular fluid collection with multiple gas and air-fluid levels along the right kidney, as well as another suspected fluid collection adjacent to the upper pole of the right kidney. The findings suggested complicated pyelonephritis with emphysematous abscess formation. Urology was consulted and they suggested a perinephric drain be placed by interventional radiology (IR). The patient progressed well and was ultimately discharged days later in stable condition. Despite its rarity, healthcare providers should consider infectious processes such as EPN in the differential for generalized weakness and promptly initiate appropriate diagnostic and therapeutic measures.

气肿性肾盂肾炎(EPN)是尿路感染罕见且危及生命的后遗症,其特征为肾实质产气性坏死感染,需要及时治疗。已发现它与未控制的糖尿病相关,由于女性更易患尿路感染,所以在女性中更为常见。早期识别和治疗EPN对于改善患者预后及预防进一步并发症至关重要。在本病例中,我们重点介绍了一例进展性肾盂肾炎合并气肿性脓肿形成并需要手术处理的病例。一名49岁女性,有糖尿病、高血压、哮喘和狼疮病史,因全身乏力到急诊科就诊。乳酸水平升高,尿液分析提示感染。腹部和盆腔计算机断层扫描(CT)显示右肾有一个大的包膜下液性聚集区,伴有多个气体和气液平面,右肾上极附近还有另一个疑似液性聚集区。这些发现提示为合并气肿性脓肿形成的复杂性肾盂肾炎。咨询了泌尿外科,他们建议由介入放射科(IR)放置肾周引流管。患者病情进展顺利,最终在几天后病情稳定出院。尽管EPN罕见,但医疗服务提供者在鉴别全身乏力的病因时应考虑到如EPN这样的感染性疾病,并及时启动适当的诊断和治疗措施。
