Emphysematous pyelonephritis is rare but frequently fatal complication of renal parenchymal infection, most commonly occurs in diabetic patients and is often associated with urinary obstruction, prior urological abnormality or infection. From 1898 to 1984, about 50 cases of emphysematous pyelonephritis have been reported universally. The diagnosis of emphysematous pyelonephritis can be made only roentgenographically. In the last 2 years, we have had two cases of emphysematous pyelonephritis at our hospital. It is our purpose to report two patients who have survived with a brief review of the provious literature.
