This document discusses different types of prostatitis, including acute bacterial, chronic bacterial, chronic prostatitis/chronic pelvic pain syndrome, and asymptomatic inflammatory prostatitis. It describes symptoms such as painful urination, pelvic discomfort, and lower back pain. Causes include bacterial infections from the urinary tract as well as pelvic trauma. Treatment involves antibiotics, warm baths, stress reduction, and avoiding irritants. A prostatic abscess may develop as a complication of acute prostatitis and requires drainage and antibiotics. Benign prostatic hyperplasia can also cause urinary symptoms as the prostate gland enlarges.
