Emphysematous pyelonephritis and cystitis in a patient with uremia and anuria: A case report and literature review.

Background: Emphysematous pyelonephritis (EPN) or cystitis (EC) is a severe infection of the urinary tract with high mortality. EPN is uncommon among the patients of end stage of renal failure (ESRD) CASE PRESENTATION:: A 38-year-old male with uremia and anuria who was on hemodialysis was found to have gas formation in the bilateral pelvis, ureters, and urinary bladder by CT scan. The diagnosis was emphysematous pyelonephritis and cystitis. And Foley catheter was placed and bladder irrigation was performed. Escherichia coli infection was identified in urine culture and antibiotic was prescribed accordingly. Gas disappeared completely and the patient recovered uneventfully.

Conclusions: This is the first case report of asymptomatic EPN and EC in uremic patient, and conservative management was optimistic in this condition. More attention should be paid to EPN and EC happening to ESRD patients.
