Prostate abscess: MRSA spreading its influence into Gram-negative territory: case report and literature review

Prostate abscess is a rare complication of an ascending urinary tract infection (UTI). Its incidence has reduced secondary to routine and early use of antibiotics for treatment of UTIs. Prostate abscess has been reported in patients with uncontrolled diabetes, prolonged indwelling urinary catheters, prostate biopsy or other instrumentation of lower urinary tract. Prostate abscess is most commonly associated with Gram-negative bacteria. Staphylococcus aureus is rarely implicated and has been reported in patients with underlying risk factors like long-term or uncontrolled diabetes, intravenous drug abuse or bacteraemia. We present a rare case of prostate abscess due to methicillin resistant S aureus without obvious risk factors.
