What is being measured
The primary outcome is the main question the study is designed to answer.
Improvement From Baseline in the Incontinence Symptom Severity Index (ISSI) in the Myrbetriq™ Group at the 2 Week Follow-up Compared to Placebo Group.
Incontinence symptom severity index is a self-assessment instrument for voiding symptom severity. It assesses 8 symptom domains: emptying, urgency, urge incontinence, nocturia, daytime frequency, stress incontinence, leakage with physical activity, and pad use. absent/mild (0-6), moderate (7-16), severe (>16).
Measured: 2 weeks
Improvement From Baseline in the Number Micturitions Per 24 Hours in the Myrbetriq™ Group at the 2 Week Follow-up Compared to Placebo Group.
Only seven patients were enrolled and two of them withdrew after the first dose. Patients did not provide baseline micturitions. They were given a voiding diary after randomization to be conducted prior to their next follow-up visit. Therefore, improvement in the number of micturitions at 2 weeks cannot be analyzed from baseline
Measured: 2 weeks
Improvement From Baseline in the Number of Incontinence Episodes in the Myrbetriq™ Group at the 2 Week Follow-up Compared to Placebo Group.
Only seven patients were enrolled and two of them withdrew after the first dose. Patients did not provide baseline number of incontinence episodes. They were given a voiding diary after randomization to be conducted pror to their next follow-up visit. Therefore, improvement in the number of incontinence episodes at 2 weeks cannot be analyzed from baseline.
Measured: 2 weeks
Improvement From Baseline in the Incontinence Symptom Severity Index (ISSI) in the Myrbetriq™ Group at the 1 Week Follow-up Compared to Placebo Group.
Only seven patients were enrolled and two of them withdrew after the first dose. Therefore, we are only left with 5 patients completing the study.

Secondary outcomes (4)
Improvement in Pain and Discomfort Perception Using a 10 Point Visual Analog Scale for Pain Assessment (VAS) at the 1 and 2 Week Follow-up.
Only seven patients were enrolled and two of them withdrew after the first dose. Therefore, we are only left with 5 patients completing the study. Visual analog scale is from 1-10 (10 being the worse possible pain).
Measured: 1 week, 2 weeks
Improvement From Baseline on the Patient Global Impression of Severity (PGI-S) at the 2 Week Follow-up.
Only seven patients were enrolled and two of them withdrew after the fist dose. Therefore, we are only left with 5 patients completing the study. PGI-S is a four item questionnaire asking for patient enumeration of their urinary symptoms when compared to symptoms prior to surgery (1= normal, 2=mild, 3=moderate, 4=severe)
Measured: 2 weeks

This outcome measure will be listed in 1) mean number of days that pain medications were taken
