Renal pseudotumours caused by xanthogranulomatous pyelonephritis

Abstract

Five cases of xanthogranulomatous pyelonephritis are described. Wilms9s tumour was suspected preoperatively in 2 of the cases and a renal tumour appeared to be confirmed at laparotomy in three. Pathological examination is diagnostic and the condition appears to be always unilateral. Nephrectomy is curative.
