Abstract
Emphysematous pyelonephritis (EPN) is a rare infectious disease affecting the renal and perirenal tissues, wherein gas formation occurs in the renal parenchyma, perinephric tissues, or collecting systems. It can be life threatening with mortality rates upto 60%. Here, we report a case series of EPN during the COVID pandemic with COVID test-positive patients who were diagnosed based on clinical signs, symptoms, and CT scans. One patient was conservatively managed, one underwent nephrectomy, and the others were treated with percutaneous drainage and pigtailing. Despite being critically ill, all the patients recovered uneventfully. Owning to the rarity of the lesion and variations in the clinical spectrum, the diagnosis of EPN is challenging. EPN requires early diagnosis and prompt management. The interventional technique depends on the clinical status of the patient and the severity of the lesion. Although the threshold of intervention is low in normal clinical practice, in covid patients, we tried to manage patients conservatively and intervened only when unavoidable.
