Inflammation of the prostate gland, usually affecting men aged 30–50. It is often caused by a bacterial infection that has spread from the urethra. A urinary catheter increases the risk. Prostatitis causes pain when passing urine and increased frequency of urination; it sometimes causes fever and a discharge from the penis. There may be pain in the lower abdomen, around the rectum, and in the lower back, and blood in the urine. Diagnosis is made by rectal examination and tests on urine samples and urethral secretions. Treatment is with antibiotic drugs. The condition may be slow to clear up and tends to recur.
