- Acute bacterial prostatitis: A sudden infection, usually from bacteria ascending the urinary tract, causing fever and marked urinary symptoms. It is uncommon but serious.
- Chronic bacterial prostatitis: A low-grade infection that lingers in the prostate and causes repeated urinary tract infections with the same organism.
- Chronic prostatitis / chronic pelvic pain syndrome (CPPS): The most common form - persistent pelvic pain and urinary symptoms without demonstrable infection, likely involving nerve sensitization and pelvic floor muscle tension.
- Asymptomatic inflammatory prostatitis: Inflammation found incidentally during testing for other conditions; it needs no treatment.
- Pain: Aching in the perineum (the area between the scrotum and rectum), lower abdomen, low back, or genitals; ejaculation may be painful.
- Urinary symptoms: Burning, frequency, urgency, a weak stream, or a sense of incomplete emptying.
- Flu-like illness: In acute bacterial prostatitis, fever, chills, and body aches come on quickly.
- Sexual symptoms: Discomfort during or after ejaculation, reduced desire, and occasionally blood in the semen - alarming to see, but usually from inflammation rather than anything sinister.
- Antibiotics: Bacterial prostatitis is treated with antibiotics that penetrate prostate tissue well, such as trimethoprim-sulfamethoxazole or ciprofloxacin - typically for two to four weeks in acute cases and longer courses for chronic bacterial infection. Finishing the full course is essential to prevent relapse.
- Alpha-blockers: Medications such as tamsulosin relax muscle at the bladder outlet, easing urinary symptoms.
- Anti-inflammatories and comfort measures: NSAIDs, warm sitz baths, and avoiding prolonged cycling can reduce pain.
- Chronic pelvic pain syndrome: Improves most with a combination approach - pelvic floor physical therapy, stress management, and medication tailored to symptoms - rather than repeated antibiotics.
- Urinary retention: A swollen prostate can block urine flow entirely, sometimes requiring a temporary catheter.
- Prostate abscess: A walled-off pocket of infection that fails to clear with antibiotics alone and may need drainage.
- Bloodstream infection: Bacteria can spread from the prostate into the blood and cause serious systemic illness, which is why fever with pelvic pain is treated urgently.
- Epididymitis: Infection spreading to the coiled tube behind the testicle, causing scrotal pain and swelling.
