Abstract:
Emphysematous pyelonephritis is a rare, severe form of necrotising infection of the kidneys and peri-nephric tissues with gas accumulation, occurring predominantly among patients with diabetes mellitus. Computed tomography scan can identify the distribution of gas in the affected reno-ureteral units and so establish and classify the diagnosis. We report a case of class 4 emphysematous pyelonephritis with emphysematous cystitis, occurring in a young Bangladeshi male, who presented with features of upper urinary tract infection. He had a background history of fibro-calculous pancreatic diabetes and chronic kidney disease. Imaging also revealed renal stones. He responded to conservative treatment.
