We report on two cases of xanthogranulomatous pyelonephritis (XGP) in children. In one patient preoperative diagnosis could be made on the basis of computerized tomography. Although XGP is a pathology diagnosis, new imagine techniques should allow its suspicion in a growing number of cases. This unusual disease should be suspected in from of a IVP showing non-functioning kidney specially when associated with urinary infection and/or lithiasis. Nephrectomy should be performed in all cases.
