Effect and Safety Of Detrol LA In Men With Overactive Bladder Symptoms With Or Without Bladder Outlet Obstruction

Study Overview
=================
Brief Summary
-----------------
The primary objective of the trial is to evaluate the effect of tolterodine ER plus tamsulosin versus placebo on patient perception of overall treatment benefit in men who have frequency and urgency, with or without urinary urge incontinence (UUI), with or without bladder outlet obstruction (BOO).
