Affected patients usually have massive destruction of the kidney due to granulomatous tissue containing lipid-laden macrophages; the appearance may be confused with renal malignancy.

Empiric antibiotics were given and fever curve went down smoothly. Xanthogranulomatous pyelonephritis with non-function kidney was impressed, and right laparoscopic radical nephrectomy was arranged. Grossly, the calyx of kidney was filled with grayish granulomatous pus (Figure 2-4.). The patient was discharged under stable condition.
