Brief summary
Currently, in clinical practice there has been no standardization in the number of injections a single dose of intradetrusor onabotulinumtoxin A is administered in. Given the increasing use of this treatment modality, the aim of this study is to compare outcomes for patients given a 100 unit dose of onabotulinumtoxin A split into 5 as compared to 20 injections for the treatment of overactive bladder or urgency urinary incontinence refractory to medical treatment.
Detailed description
The intradetrusor injection of onabotulinumtoxin A for treatment of idiopathic overactive bladder and urgency urinary incontinence refractory to anticholinergic or β-agonist treatment was approved by the United States Food and Drug Administration (FDA) in 2013. Since then, multiple randomized placebo-controlled trials have demonstrated the effectiveness of the treatment. Currently, Allergan, Inc. and the FDA recommend the intravesical administration of onabotulinumtoxin A with dilution to 100 units/10 mL with preservative-free 0.9% Sodium Chloride Injection, as 20 injections of 0.5 mL each. Currently, in clinical practice there has been no standardization in the number of intravesical injections, with a single dose of onabotulinumtoxin A being administered in as few as 1 injection to as many as 40 injections into the detrusor muscle. Given the increasing use of this treatment modality, the investigators aim to compare patient outcomes for patients given a 100 unit dose of onabotulinumtoxin A split into 5 as compared to the recommended 20 injections for the treatment of idiopathic overactive bladder or urgency urinary incontinence refractory to medical treatment.
Interventions
Intradetrusor onabotulinumtoxin A is administered cystoscopically with 100 unit dose given as either 5 or 20 injections in a single procedure based on the arm the participant is randomized into.

Masking description
Participants are randomized into one of two treatment arms (receiving 5 versus 20 injections per treatment with intradetrusor onabotulinumtoxin A) and are not notified of which arm they are participating in.

Eligibility
Inclusion criteria
* Women \>=18 years of age with diagnosis of urinary urgency, urinary frequency, urgency urinary incontinence, overactive bladder. * Procedure scheduled in either the outpatient clinic or the operating room to be performed without use of sedation, general, or neuraxial anesthesia.
Exclusion criteria
* Male gender. * Women \<18 years of age. * Non-English speaking. * Pregnancy (patient will self-report pregnancy). * Participant has symptoms of overactive bladder due to any known neurological reason (e.g. spinal cord injury, multiple sclerosis, cerebrovascular accident, Alzheimer's disease, Parkinson's disease, etc.) * Participant uses clean intermittent catheterization or indwelling catheter to manage urinary incontinence. * Participant has a history or current diagnosis of bladder cancer or other urothelial malignancy. * Participant has a known allergy or sensitivity to any botulinum toxin preparation. * Participant has any medical condition that may put her at increased risk with exposure to onabotulinumtoxin A, including diagnosed myasthenia gravis, Eaton-Lambert syndrome, or amyotrophic lateral sclerosis. * Participant is scheduled for administration of onabotulinumtoxin A with use of sedation, general, or neuraxial anesthesia.
