[Renal carbuncle and perirenal abscess in children and adolescents].

Renal abscesses are rare in childhood. The diagnosis is often complicated by non-specific symptoms and the typical signs of urinary tract infections are frequently absent. The currently available imaging methods are necessary and helpful for a differentiated therapeutic approach; nevertheless, cases are continuously being found in which a renal abscess is only diagnosed intraoperatively. In most patients a combined intravenous therapy including an antibiotic which is effective against staphylococci is sufficient. The therapy is supported if necessary by percutaneous abscess drainage. Open revision or even nephrectomy is rarely required.
