Nephron-sparing surgery in case of emphysematous pyelonephritis.

Emphysematous pyelonephritis is fatal necrotizing infection where life saving emergency nephrectomy is recommended for severe cases, but we performed nephron sparing surgery. Elderly diabetic female presented with left flank pain and fever for 15 days. On examination tender lump was palpable in left lumbar region. Investigations showed hyperglycemia, leucocytosis and creatinine 3.0 mg/dl. NCCT-KUB suggested class 3B-EPN. Following emergency pigtail, a repeat CT-scan suggested upper and lower pole destruction. In open drainage both poles debrided with sparing of middle pole. Follow-up CECT-KUB showed spared kidney with normal function. No literature for nephron sparing surgery in similar cases of EPN was found.
