RESUMEN
Emphysematous pyelitis is uniquely characterized by gas-forming infection restricted to the renal collecting system. This disease entity is uncommon, and shows preferred occurrence in patients with diabetes mellitus or urinary tract obstruction. We report a case of bilateral emphysematous pyelitis in a diabetic end-stage renal disease patient undergoing peritoneal dialysis therapy. The patient was treated by medical treatment only and then recovered from infection, and she has maintained peritoneal dialysis until today. The authors report this case as a successful medical treatment for emphysematous pyelitis accompanying multiple risk factors, such as diabetes mellitus, amorphous medullary kidney stones, and even underlying maintaining peritoneal dialysis.
