Cases 1 and 2 were a 84-year-old, 64-year-old female relatively. Case 2 had a history of uncontrolled diabetes mellitus. Both cases were referred to our hospital with a chief complaint of high fever. Initial diagnosis was acute pyelonephritis based on the findings of pyuria and right costovertebral angle knock pain. Abdominal computed tomography (CT) scan revealed a gas shadow in the right renal pelvis and calyx with right ureteral stone. The definitive diagnosis was emphysematous pyelonephritis (EPN). We selected transureteral catheterization into the right ureter immediately. Escherichia coli was identified from urine culture. Conservative therapy with antibiotics was also effective and general condition improved. Herein we discussed the etiology, symptomatology, choice of treatment and prognosis of emphysematous pyelonephritis. Recently CT is an effective imaging method for diagnosis at an early stage. Antibiotics therapy combined with transureteral drainage of gas-forming urolithiasis is effective as the initial conservative therapy.

Emphysematous pyelonephritis (EPN) is a rare but severe necrotizing infection often associated with diabetes, ureteral obstruction, and gas production in the renal parenchyma and perinephric area. This report describes a 54-year-old man with type 2 diabetes who presented with right lumbar pain and was diagnosed with EPN complicated by right ureteral calculi and perinephric gas accumulation. Despite initial improvement with fluid resuscitation, antibiotics, and drainage, inadequate blood glucose control led to a worsening of the infection, eventually involving the psoas major muscle and iliac vessels.

Emphysematous pyelonephritis is a necrotizing infection of the renal parenchyma by gas-forming organisms, with a risk of the gas extending into peri-nephric or para-renal spaces and in advanced cases, the involvement may be extensive and bilateral. It is a common complication in patients with long-term diabetes, primarily caused by Gram-negative organisms or, in some cases, anaerobes. The diagnosis of emphysematous pyelonephritis is made by clinical features and confirmed by computed tomography.

BACKGROUND Emphysematous urinary tract infections are rare and serious conditions that are often multifactorial in etiology and may be associated with the presence of renal stones. Diagnosis can be made by finding gas within the renal collecting system or parenchyma. However, the radiographic finding of gas within a renal stone is rare and little has been published to describe the significance of this finding, its promoting factors, and management.
