Nonbacterial Prostatitis. In nonbacterial prostatitis, inflammation occurs, but no bacteria are present. It is 8 times more common than bacterial prostatitis. The causes of nonbacterial prostatitis have not been determined. In one study, alfuzosin, an alpha-blocker drug that is used for BPH, provided some modest relief in patients with prostatitis and chronic pain. The routine use of drug therapy does not seem to help this condition. More research is needed.
Prostatodynia. Although it is considered a form of prostatitis, prostatodynia is a noninflammatory disorder characterized by prostate pain, but neither inflammation nor bacteria are present. The causes of prostatodynia are unknown.
Congestion of the Prostate (Prostatosis)
Congestion of the prostate, sometimes called prostatosis, is a benign condition in which the prostate seems to be swollen by excess fluid. It can cause frequent, slow, or uncomfortable urination, but it responds well to a program of frequent ejaculation and sitz baths.
Prostate Cancer
On occasion, prostate cancer can mimic BPH, since both conditions may cause obstruction of the urethra. Bladder cancer can sometimes cause urinary bleeding, frequency of urination, or a sense of urgency, also symptoms of BPH.

Other Conditions Affecting the Urinary Tract
Several other conditions can impair the lower urinary tract, including tumors, reactions to medications, and spinal cord injuries. Diseases that affect the nervous system, such as diabetes, multiple sclerosis, and shingles, can desensitize the nerves so that they fail to sense fullness and do not trigger the contraction of the bladder.
