Emphysematous urinary tract infections (EUTIs) are rare, severe, and suppurative infections affecting various parts of the urinary tract. We report a case of a 75-year-old male presenting with hematuria and generalized weakness with uncontrolled diabetes mellitus (DM) and hypertension. He tested positive for COVID-19 on the second day of hospital admission. A non-contrast-enhanced CT of the abdomen and pelvis revealed gas within the left renal parenchyma, walls of the left ureter, and urinary bladder, establishing the diagnosis of EUTIs. The patient was treated using intravenous antibiotics without any surgical intervention, and four weeks later was stable and transported to long-term acute care (LTAC) facility. DM is the most common risk factor for the development of EUTIs and Escherichia coli is the most common causative pathogen.
