Prostatitis is the general term for inflammation of the prostrate gland. As with benign prostatic hyperplasia (BPH), the inflamed prostate pinches the urethra, resulting in many of the same symptoms; frequent and urgent urination, increased night-time urinating, and a stop-and-start urine stream. Other symptoms include pain between the rectum and the back of the scrotum, in the lower back, above the pubic bone, in the lower abdominal area, or in and around the groin and testicles. Prostatitis can also result in dysuria which is painful or difficult urination. Prostatitis with no known cause may be termed nonbacterial prostatitis.
