An on-line fillable questionaire of BPH symptoms on the Flomax website.  The questionaire calculates the AUA BPH Symptom Index Score that is often used by urologists to determine the severity of prostate problems.

A score of 0-7 is mild, 8-19 is moderate, and over 20 is considered severe.

Although the site is sponsored by a drug company, it contains useful information for BPH sufferers.
