Patients with diabetes account for 85-100% of cases. The current treatment is one of the potent antimicrobial therapies together with kidney drainage and fluid resuscitation. Nephrectomy should be considered if patients deteriorate or do not improve on conservative treatment. We report a case of 62-year-old woman with multiple comorbidities, with a diagnosis of EPN whose condition did not improve despite the standard treatment approach.Keywords: Emphysematous, pyelonephritis, nephrectomy, diabetes
