A Rare Case of Prostatic and Bilateral Renal Abscesses Caused by Community-acquired Methicillin-resistant Staphylococcus aureus Infection.

Gram-negative bacilli are usually implicated in the formation of prostatic abscesses (PA) which is a rare complication of prostatitis. However, PA methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a substantial cause of PA in recent years. Predisposing factors for MRSA prostatitis include immunocompromised states such as human immunodeficiency virus (HIV), uncontrolled diabetes, intravenous drug use (IVDU), urethral instrumentation, bladder outlet obstruction, preexisting prostatic disease, recent prostatic procedure, and chronic dialysis among others. MRSA PA should be promptly diagnosed and appropriately treated as delay in diagnosis can be detrimental. We present a case of a patient with a remote history of IVDU who developed simultaneous bilateral renal and PA caused by MRSA in the absence of MRSA bacteremia. Since our patient did not have the traditional risk factors for MRSA infection, we can argue that he was infected by the community-acquired strains of MRSA.
