Arms	Assigned Interventions
1. Tamsulosin alone: Placebo Comparator	Drug: Tamsulosin hydrochloride oral
2. Tamsulosin + solifenacin (low dose): Experimental	Drug: Tamsulosin hydrochloride oral Drug: Solifenacin succinate oral
3. Tamsulosin + solifenacin (high dose): Active Comparator	Drug: Tamsulosin hydrochloride oral Drug: Solifenacin succinate oral

Detailed Description:

Study drugs are administered for 14 weeks in total, including a 2-week run-in period (single blind) and a 12-week treatment period (double blind). After written informed consent, study drugs for the run-in period are orally administered once daily after breakfast for two weeks to subjects who fulfill the inclusion and exclusion criteria. Then, subjects are randomized and orally treated with study drugs for the treatment period once daily after breakfast for 12 weeks
