title: [Emphysematous pyelonephritis. A serious complication of diabetes mellitus].
abstract: Pyelonephritis emphysematous (PE) is a life threatening renal infection which is observed practically exclusively as a serious complication of diabetes mellitus. 95% of the 73 cases which have been reviewed were found in diabetic patients. The symptomatology resembles that of severe acute pyelonephritis but the disease differs from this in that, in PE, emphysema develops in the actual renal parenchyma and/or in the perirenal tissues. The most important single factor in the etiology appears to be ischaemia of the tissues which are employed as growth media for the microorganisms involved. Infections with E. coli, Klebsiella pneumoniae, Aerobacter and Proteus are the most commonly found. Isolated cases with Candida and Cryptococcus neoformans have been observed. The mortality in untreated cases of PE is 100%. With medical treatment alone, the mortality decreases to 73% while, when combined medical and surgical intervention is employed, the mortality can be reduced to 30%.
