[Emphysematous pyelonephritis. Two cases]. / La pyélonéphrite emphysémateuse. A propos de deux observations.

The emphysematous pyelonephritis is a rare and severe renal infection characterized by the presence of gas in renal parenchyma and its perirenal spaces. We report two cases of emphysematous pyelonephritis in two diabetic women (53 and 50 years old respectively). In the first case, the treatment was based on nephrectomy because of the presence of a septic shock and three risk factors, which are acute renal failure, hematuria and thrombopenia. In the second case, the treatment was only medical. The evolution was favorable in the two cases. We insist in this article that this diagnosis should be considered in every female diabetic patient having severe acute pyelonephritis resistant to a well-conducted medical treatment.
