This study is for women diagnosed with urinary urgency incontinence (UUI) or overactive bladder (OAB). Some patients continue to have symptoms even while taking medication for OAB. The purpose of this study is to estimate the number of women who respond to a medication called mirabegron and estimate change in symptom severity over 12 weeks of therapy. A secondary goal is to correlate the female urinary microbiome (FUM) with response to treatment and change in symptom severity over 12 weeks of therapy.
Mirabegron is an FDA-approved medication for urgency incontinence. Evaluation of mirabegron's influence on clinical symptoms may need to take into account the effect of the female urinary microbiome (FUM) on a patient's response to treatment. Compared to asymptomatic patients, several bacterial species are more common in patients with overactive bladder. Currently, physicians have limited ability to personalize a patient's urinary urgency incontinence treatment and, consequently, the prescribed medication may provide minimal symptom relief. Since the FUM can be assessed prior to treatment, this study proposes to determine if baseline FUM assessment can provide insight into future symptom relief with mirabegron treatment.

Response to Therapy
Response to therapy was measured using the Patient Perception of Bladder Control (PPBC) questionnaire which measures patients' perceived bladder condition on a 6-point ordinal scale ranging from 1 (no problems at all) to 6 (many severe problems). Women reporting a PPBC score of 4 or 5 by week 12 responded to therapy. Women reporting a PPBC score of 1, 2, or 3 by week 12 did not respond to therapy.
Time frame: 12 weeks
Change in Overactive Bladder Questionnaire (OAB-q) Health Related Quality of Life (HRQL)
The Overactive Bladder Questionnaire (OAB-q) Health Related Quality of Life (HRQL) score is a measure of patients' bladder symptom severity. It ranges from 25 to 150 where higher scores indicate greater quality of life.
Time frame: 12 weeks
Change in Urinary Distress Inventory (UDI)
The Urinary Distress Inventory is a 29-item questionnaire that asks patients to report how bothered they are by symptoms of urinary urgency on a scale from 1 (not at all) to 4 (quite a bit). The total score ranges from 0 to 300 where higher scores indicate worsening symptom severity.
Time frame: 12 weeks
Change in Pelvic Organ Prolapse Distress Inventory (POPDI) Score
The Pelvic Organ Prolapse Distress Inventory (POPDI) is a 16-item questionnaire that asks patients to report how bothered they are by symptoms of urinary urgency on a scale from 1 (not at all) to 4 (quite a bit). The total score ranges from 0 to 300 where higher scores indicate worsening symptom severity.
Time frame: 12 weeks
Change in Colo-Rectal-Anal Distress Inventory (CRADI)
The Colo-Rectal-Anal Distress Inventory (CRADI) is a 17-item questionnaire that asks patients to report how bothered they are by symptoms of urinary urgency on a scale from 1 (not at all) to 4 (quite a bit). The total score ranges from 0 to 400 where higher scores indicate worsening symptom severity.
