Prostatitis is inflammation of the prostate gland that can be caused by bacterial infection or occur without infection (chronic pelvic pain syndrome). It often leads to pelvic or perineal pain, urinary frequency, urgency, painful urination, and discomfort during or after ejaculation. Acute bacterial prostatitis typically presents with fever, chills, and a tender, enlarged prostate, while chronic forms cause milder, recurring symptoms. Diagnosis is based on history, physical exam, urine or prostatic fluid cultures, and sometimes imaging. Treatment depends on the type—ranging from antibiotics for bacterial causes to alpha-blockers, anti-inflammatories, or pelvic floor therapy for chronic nonbacterial cases.
