Renal cortical suppurative infection
Renal cortical suppurative infection is a serious infection caused by Staphylococcus aureus entering the renal cortex through the blood. When there is no liquefied renal inflammatory mass, it is called acute focal bacterial nephritis. When an abscess is formed, it is called renal cortical abscess or suppurative nephritis. When several abscesses merge, it is called renal carbuncle. With the development of broad-spectrum antibiotics today, the incidence of renal cortical suppurative infection has decreased compared with the past due to the timely use of antibiotics to control the primary infection focus, and most of them are manifested as acute focal bacterial nephritis.
