Emphysematous pyelonephritis: outcomes of conservative management and literature review.

Emphysematous pyelonephritis (EPN) is a rare, necrotising infection of the renal parenchyma, predominantly associated with Escherichia coli infection and unless promptly recognised and dealt with, it carries a poor prognosis. The current treatment is one of antimicrobial therapies together with nephrectomy in a majority of patients. We report an elderly man with multiple comorbidities with a diagnosis of EPN whose condition improved with antimicrobial and supportive therapy, and no surgical intervention was required. © BMJ Publishing Group Limited 2018.
