Complicated perirenal abscess: Diagnostic and therapeutic approach: case report.

Abstract

Perirenal abscess is an uncommon but potentially life-

threatening infection of the perirenal space, associated with

high morbidity and mortality when diagnosis and treatment

are delayed. Its clinical presentation is often nonspecific,

making early recognition difficult and favoring progression

to sepsis and organ failure. Predisposing factors include

diabetes mellitus, urinary tract obstruction, nephrolithiasis,

and recurrent urinary tract infections. Diagnosis relies on

clinical suspicion supported by imaging studies, with

computed tomography being the diagnostic modality of

choice. Treatment depends on abscess size, patient clinical

status, and response to antibiotic therapy, and may require

percutaneous or surgical drainage. We present the case of a

male patient with a complicated left perirenal abscess

requiring hospital management, along with a narrative review

of the literature focusing on its pathophysiology, diagnosis,

and therapeutic options.
