Diagnoses
You may first notice symptoms of BPH yourself, or your doctor may find that your prostate is enlarged during a routine check-up. The doctor can determine the size of the prostate gland during a physical examination.

The diagnosis is made with several of the following tests:

Symptom Score
This is a brief questionnaire that provides a numerical value to the symptoms associated with urination.  The higher the score (maximum is 25), the more symptoms a man has and the more likely he will want to have treatment for relief of his symptoms.

Urinalysis
A urine sample is taken to look for signs of blood and infection.
