Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The null hypothesis for this study is that the combination of solifenacin and Percutaneous Tibial Nerve Stimulation (PTNS) is not different from PTNS alone. However the investigators anticipate a 20% improvement in patients receiving combination therapy as measured by the OAB-q (Overactive Bladder questionnaire) scores.
