Pyélonéphrite xanthogranulomateuse

Overview

Xanthogranulomatous Pyelonephritis is a rare and severe form of chronic kidney infection characterized by destruction of kidney tissue and replacement with inflammatory cells and lipid-laden macrophages.

This condition is often associated with long-standing urinary tract obstruction and infection. It usually affects one kidney and may require surgical treatment if severe.
