Psoas Abscess Secondary to Urinary Tract Fungal Infection

摘要

Psoas abscess is a rare condition where infection spreads from a nearby or distant septic focus to the psoas sheath. The causative bacterial organisms at distal sites reach the psoas via lymphatic or hematogenous spread, whereas infection from nearby sites that include the urinary system reaches the psoas directly. There are few reports that account for bacterial infection after endourological procedures as the cause of direct spread of infection to the psoas muscle.² We report a case of psoas abscess caused by fungal infection that spread from an injured left ureter to the psoas sheath.
