The purpose of this study is to determine whether combination therapy with Tolterodine ER and Tamsulosin is more effective than monotherapy with tamsulosin alone in reducing stent symptoms. The second purpose is to determine if people have less stent discomfort if they take these medications starting 2 weeks before the stent is placed The investigators hope to show that the addition of Tolterodine ER to Tamsulosin will provide added benefits in reducing stent symptoms in patients who have had unilateral placement of a ureteral stent.
