title: Emphysematous pyelonephritis.
abstract: Emphysematous pyelonephritis is an uncommon infection of the renal parenchyma found most often in diabetic patients. The fortieth case of emphysematous pyelonephritis is reported and a plan for management is proposed based on differentiating this condition from gas-forming infections of the perinephric space and the renal collecting system.
