kidney abscess

An abscess in the kidney, typically following pyelonephritis or a blood-borne infection. The most common causative organisms are gram-negative bacteria from the lower urinary tract that spread to the kidneys and Staphylococcus aureus from a blood-borne infection. Immunocompromised patients may develop abscesses caused by Nocardia, Candida, or Aspergillus. Occasionally, Mycobacterium tuberculosis and Echinococcus are responsible agents. Synonym: renal abscess


Antimicrobial agents are used in combination with surgical drainage. Occasionally, nephrectomy or retroperitoneal exploration is required.
