The first step: one-tailed test: the electroacupuncture group vs Solifenacin group is 79.5% VS 54.8%( α=0.05, β=0.20, n=51). The second step: two-tailed test :the electroacupuncture group vs Placebo group is 54.5% VS 20.9%,(α=0.05, β=0.20, n=37). To combine the first and second step, 51 cases in each group are needed. Allowing for a 10% dropout, 57 cases in each group are needed. So we set the sample size is 60.
