Extensive bilateral emphysematous pyelonephritis with calculi managed conservatively with antibiotics and DJ stent

Bilateral emphysematous pyelonephritis cured by antibiotics alone in a black African woman

A 78-year-old black woman with a 10-year history of diabetes mellitus was admitted to the intensive care unit. Upon admission, she presented with chills, nausea, and left flank pain. The presence of hyperglycemia (fasting blood glucose, 19.7 mmol/L) and an altered consciousness required immediate treatment with insulin analog. Laboratory investigations and enhanced computed tomography scan led to the diagnosis of bilateral emphysematous pyelonephritis (EPN). The patient responded well to conservative treatment with antibiotics, and was finally discharged after 22 days when the computed tomography scan showed resolution of all the pockets of air. This case and associated literature review of 25 previously reported cases of bilateral EPN show the changing trend of EPN management from emergency nephrectomy toward conservative treatment with potent antibiotics and/or percutaneous drainage, and has been associated with higher survival rates compared to emergency nephrectomy.
