Xanthogranulomatous pyelonephritis in children. Report of 7 cases and one associated with nephroblastoma

8 cases of XGP in children are reported. The presence of urolithiasis together with xanthogranulomatous lesion in 7 cases and of nephroblastoma in one may be of help in understanding the aetiopathogenesis. In all the cases the involved kidney did not function thus necessitating subcapsular nephrectomy via retroperitoneal approach.
