Emphysematous pyelonephritis is a lifethreatening necrotizing kidney infection, characterized by accumulation of gas in the renal parenchyma and the surrounding tissues. Although it is most commonly seen in diabetic and inmunosupressed patients, it has also been reported in people suffering from obstruction of the kidney. It has a very high mortality and needs to be treated rapidly and aggressively. There have been reviewed 45 cases of high urinary infection treated at the San Juan de Dios Hospital, which show two emphysematous pyelonephritis cases. This text reports the findings and the patients response to the surgical treatment.
