Chronic bacterial prostatitis (CBP) is most often caused by Escherichia coli or other gram-negative Enterobacteriaceae, and typically affects men 36 to 50 years of age. After an episode of acute bacterial prostatitis, approximately 5% of patients may progress to CBP. [1] Patients may present with a history of relapsing urinary tract infections (UTIs), which may be episodic or persistent. The UTIs are typically not associated with systemic signs of infection. Other irritative or obstructive urologic symptoms may also be present. (See Presentation).
