[Emphysematous pyelonephritis and perinephritis].

The authors report an eighth case of emphysematous perinephritis and a new case of emphysematous pyelonephritis. The general features of these two diseases and their similarities are described: middle aged diabetic women, clinical picture of sepsis, gas images projected over the renal area with delayed excretion on intravenous pyelography, computed tomography reveals the exact site of the emphysematous images (perinephritic and or intraparenchymal). Emphysematous perinephritis may be an early form of emphysematous pyelonephritis. Surgical drainage of the renal compartment allows conservative management at this early stage.
