Brief Summary
Patients with overactive bladder (OAB) will be randomly assigned (like a flip of a coin) to receive 100 units of onabotulinumtoxinA injected into the bladder at either 3 sites or 10 sites. Patient satisfaction and the effectiveness of the medication will be evaluated.

Outcome Measures
Primary Outcomes (1)
Number of Incontinence Episodes Per Day
Participants will be asked to complete a 3-day voiding diary. On the diary participants will record the number of occurrences of voids over a 24 hour period for 3 consecutive days. Number of voids at 3 months are recorded.
3 months after the initial injection
Secondary Outcomes (6)
