Study Summary

OnabotulinumtoxinA is an effective treatment for both idiopathic and neurogenic overactive bladder and was FDA approved for this indication in 2013. The standard technique for injecting onabotulinumtoxinA into the detrusor is mixing 100 units of onabotulinumtoxinA into 10mL of injectable normal saline and injecting 20 sites with 0.5mL in the posterior wall of hte bladder for idiopathic overactive bladder and mixing 200 units into 30mL and injecting 30 sites with 1mL for neurogenic overactive bladder. The purpose of this study is to compare the efficacy of a technique using a reduced number of injections with the same dosage of onabotulinumtoxinA to the standard technique. The hypothesis is that the reduced technique will not be inferior in terms of efficacy as the standard technique and that there will be a lower incidence of urinary tract infections and urinary retention requiring catheterization post-procedure.

Primary Outcome

The overactive bladder questionnaire short form is a validated questionnaire assessing both symptoms and quality of life related to overactive bladder. The survey has two subscales, a health related quality of life scale and a symptom severity scale. Each subscale is scored separately with a range of 0 to 100. For health related quality of life a score of 0 indicates worst quality of life and 100 indicating best quality of life. For symptom severity, the scores also range from 0 to 100 but with
