PRIMARY outcome

Timeframe: Baseline to 4 weeks after initial treatment

Population: Control arm: subject number S025 was removed from analysis for not meeting the requirement for analysis, thus control arm 27 subjects

Efficacy: Mean change of the total frequency per 3 days from baseline to 4 weeks after the treatment day based on the 3-day voiding diary. Change = Week 4 minus Baseline value

Efficacy:(measured the net change of variables from baseline to 1 month) Overactive bladder symptom score (OABSS) The OABSS is a 4-item questionnaire developed to evaluate OAB symptoms. The maximal scores are 2, 3, 5 and 5 for daytime frequency, nighttime frequency, urgency and urgency in continence, respectively. The OABSS range = 0 to 15 ((asymptomatic to very symptomatic). Change = Week 4 minus Baseline value
