2024年9月27日 · Renal abscess — Focal renal abscesses typically occur in the setting of pyelonephritis, particularly in patients with anatomical abnormalities that predispose to infection.

Pyelonephritis in general, emphysematous pyelonephritis, malakoplakia, and xanthogranulomatous pyelonephritis are discussed in detail separately. Renal and perirenal abscesses can complicate …

Xanthogranulomatous pyelonephritis (XPN) is an unusual variant of chronic pyelonephritis. Most cases occur in the setting of obstruction due to infected renal stones [1-6].

Autopsy examination showed a confluent bronchopneumonia with several small abscesses and acute pyelonephritis with abscess formation. Legionella pneumophila, serogroup 4, was isolated in pure culture from lung tissue postmortem and was also shown by direct immunofluorescence in the kidney and spleen.

This topic will review the approach to adults with acute complicated UTI, which we define as a UTI that has possibly extended beyond the bladder (ie, UTI with fever or other systemic symptoms, suspected or documented pyelonephritis, and UTI with sepsis or bacteremia).

Renal abscesses can be managed by medical treatment only, reserving interventional treatment for large collections or patients with clinical impairment. Early diagnosis is an important factor in the outcome of renal and perinephric abscesses.

An infected cyst and acute pyelonephritis are the most common kidney infections, although complications such as a perinephric abscess and bacteremia can occur [ 3,4 ].

2024年4月5日 · Acute complicated UTIs not complicated by gas formation and renal abscesses are discussed in detail elsewhere. (See "Acute complicated urinary tract infection (including pyelonephritis) in adults and adolescents" and "Renal and perinephric abscess".)

Septation of the perinephric abscess is frequent, which makes drainage more difficult than that of renal abscess. Focal renal abscesses typically occur in the setting of pyelonephritis …

Low suspicion for infected cyst – For patients who have acute pyelonephritis without a suspected infected cyst or abscess, we treat with antimicrobial therapy for a minimum of 10 to 14 days.
