Study population: Women with overactive bladder syndrome who completed urodynamic study and bladder diary and received Mirabegron 25 mg per day

Brief summary: Recurrence of female overactive bladder syndrome (OAB) is not uncommon. It is important to decrease the recurrence of female OAB. However, factors predicting recurrence of female OAB, especially for those women who need retreatment is undetermined. Thus, the aim of this study was to elucidate factors predicting retreatment of female OAB.

Detailed description: The medical records, including pad testing, urodynamic studies, lower urinary tract symptoms related questionnaires and bladder diaries of all consecutive women with OAB, who visited urogynecologic clinics in a tertiary referral center, were reviewed. Persistence interval was defined from the date of prescription of mirabegron to the date of discontinuation of mirabegron treatment. Statistical analysis was performed with Kaplan-Meier estimator. Multivariable Cox proportional-hazard model with all variables with p \< 0.25 in the univariate analysis was performed to predict OAB retreatment probability.
