Hong, Sung Joo

Abstract

Perinephric abscess is a collection of pus in the space between the kidney and Gerota's fascia. The abscess usually is confined to Gerota's fascia but may extend in several directions, such as a draining flank abscess through Petit's triangle or subphrenic abscess. Rarely, this abscess perforates interpersonally or into the colon. Recently the majority of perinephric abscesses revealed that Gram negative organisms are more prevalent and are attributable to renal disease.
