Xanthogranulomatous Pyelonephritis in a Surgically Complicated Patient: A Case Report

Abstract

ABSTRACT Xanthogranulomatous pyelonephritis is an uncommon destructive process that is associated with urinary tract infection and/or obstruction. We present the case of a 63 year old female who had an unusual case of xanthogranulomatous pyelonephritis due to Streptococcus intermedius in the left kidney. CT scan revealed a chronic obstructive pyelonephritis with associated staghorn calculi, and renal histopathology confirmed xanthogranulomatous pyelonephritis with foamy macrophages. She was a surgically complicated patient, who underwent two ventral hernia repairs along with her left nephrectomy. She ultimately had a complete recovery after surgical treatment and antibiotics.
