title: Bilateral emphysematous pyelonephritis with perirenal abscess cured by conservative therapy.
abstract: Emphysematous pyelonephritis is a rare life-threatening infection of the renal parenchyma. It usually affects unilateral kidney and occurs mostly in diabetic patients. It is characterized by the presence of gas within the renal parenchyma and requires prompt diagnosis and early aggressive therapy. Bilateral emphysematous pyelonephritis is even more rare and is associated with high mortality. We describe a case of a 62-year-old diabetic woman who presented with nonketotic hyperosmolar coma and bilateral emphysematous pyelonephritis caused by Klebsiella pneumoniae. Diagnosis of bilateral emphysematous pyelonephritis was confirmed by an abdominal computed tomographic scan and microbiologic studies. Our patient was successfully treated using percutaneous catheter drainage and long-term antibiotic therapy.
