Brief Summary:
Abstract
Introduction: Urgency Urinary Incontinence (UUI) is a common condition with a prevalence of 9-31% in women in the United States. Despite current treatments, a high number of women have symptoms refractory to first- and second-line treatment approaches.
Aims: The primary aim of this randomized controlled trial is to compare the efficacy of percutaneous tibial nerve stimulation (PTNS) and mirabegron treatment versus PTNS with placebo on change in the number of UUI episodes over a 12-week treatment course. Secondary aims include comparing the efficacy of combined treatment of PTNS and mirabegron versus PTNS with placebo on improvement in urinary incontinence symptom specific distress and quality of life related to UUI over a 12-week course of PTNS.
Methods: A total of 54 consented participants will be recruited and randomized with 27 patients in the PTNS with mirabegron (daily 50 mg dose for the 12-week course) group and 27 patients in the PTNS with placebo group. Demographics and baseline data will be analyzed by student's t-test and chi-squared test or Fischer's Exact test as appropriate.
Hypothesis: We anticipate that combination therapy will prove superior to monotherapy for reducing the number of UUI episodes over a 12-week treatment course.

Detailed Description:
Specific Aims:
Introduction/Background: Urgency Urinary Incontinence (UUI) remains a challenging clinical problem for urogynecologists as they treat women and seek to find better therapies. There is a wealth of literature addressing individual therapies for first, second, and third line treatments for UUI. There are three main third line treatment options for UUI including percutaneous tibial nerve stimulation (PTNS), sacral neuromodulation, and intradetrusor botox. At the current time, there are limited studies that have looked at a combination of second and third-line therapy therapies for UUI. While some anticholinergic medications have been studied in combination with percutaneous tibial nerve stimulation (PTNS) such as solifenacin, tolterodine, and trospium, there is limited data on the combination of mirabegron, a beta-3 agonist, and PTNS for treatment of refractory UUI. The studies that looked at anticholinergic medications in combination with PTNS revealed improvement in UUI compared to PTNS plus placebo. However, there are patients who do not tolerate anticholinergic medications well because of side effects. A relatively new finding as reported by the American Urogynecologic Society (AUGS) about avoiding anticholinergic medications in women greater than age 70 secondary to increased risk for cognitive impairment, dementia, and Alzheimer's disease is further impetus to conduct this trial \[1\]. The rationale for studying mirabegron in combination with PTNS versus PTNS plus placebo is important as mirabegron does not have the significant side effect profile that anticholinergic medications have and better tolerated in the older population. Therefore, more research should be performed to evaluate the effect of the combination of mirabegron and PTNS for refractory UUI. The purpose of this study is to evaluate the combination of PTNS and mirabegron and compare that to PTNS plus placebo in the treatment of refractory UUI.
Hypothesis: Combination therapy of PTNS and mirabegron, a beta-3 agonist, will contribute to greater improvement in the number of urgency urinary incontinence episodes as measured by a 3-day bladder diary compared to PTNS plus placebo in women.
Method: This is a randomized clinical trial comparing the efficacy of combination therapy with PTNS plus mirabegron to PTNS plus placebo in women with refractory urgency urinary incontinence.
Primary Aim: The primary aim of this study is to compare the efficacy of combined treatment of PTNS and mirabegron versus PTNS plus placebo on change in the number of UUI episodes at 12 weeks.
Secondary Aims:
* Comparing urinary symptom specific distress and quality of life over a 12-week course of PTNS.
* Comparing the side effect/adverse event profile of combined treatment of PTNS and mirabegron versus PTNS plus placebo over a 12-week course of PTNS
* Comparing the treatment efficacy and adverse events of combined treatment of PTNS and mirabegron versus PTNS plus placebo in women \> 70 years of age as a sub analysis within the study
