[10 cases of xanthogranulomatous pyelonephritis]

Xanthogranulomatous pyelonephritis (XGP) is a chronic inflammation of the kidney usually associated with renal stones, recurrent urinary tract infections or endocrine disorders. A correct preoperative diagnosis is rarely made, since no specific clinical or radiological pattern is known. Differential diagnosis must include renal tuberculosis and renal carcinoma. Ten cases of XGP are reported. Clinical findings, radiological and pathological features, biolaboratory abnormalities are discussed.
