Emphysematous renal tract disease due to Aspergillus fumigatus.

Emphysematous renal tract disease (ERTD) is a rare necrotizing infection of renal parenchyma and/or urinary tract caused by gas producing organisms. A case of acute emphysematous renal tract disease (ERTD) (emphysematous pyelonephritis along with emphysematous cystitis) caused by Aspergillus fumigatus in a non-diabetic patient, who did not apparently have any risk factor for fungal infection, is presented. Patient had refused for any surgical intervention. He was treated successfully with liposomal amphotericin B and 5-flucytosin and achieved complete recovery. Various causes of ERTD and available therapeutic options are discussed.
