In-office Assessment of Voiding Function Following Botox Injection for Overactive Bladder

In-office Assessment of Voiding Function Following Botox Injection for Overactive Bladder; Does Measuring Post Void Residual Impact Management

The purpose of this study is to describe the rates of elevated post void residual (PVR) (defined as >200mL) in Cincinnati Urogynecology Associates patients following Botox injection, as well as to document how many patients required treatment with clean intermittent self-catheterization (CISC).

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Approximately 16% of all women have symptoms of overactive bladder (OAB), whereas 30% of the elderly population are affected. Patients who do not respond to, or cannot tolerate, first and second line therapy with behavioral modifications and pharmacotherapy are offered additional treatment options. Third line therapy involves injection of onabotulinumtoxinA (Botox©, Allergen) into the bladder detrusor muscle.

Botox was approved for use for the diagnosis of OAB in 2013. Cincinnati Urogynecology Associates (CUA), TriHealth Inc. has incorporated intravesical Botox injections into the management algorithm for refractory OAB, since 2014. Currently, patients who fail to improve after a trial of first and second line therapy are offered treatment with Botox.

The standard practice is to request patients return to the office for a routine PVR measurement using straight catheterization within approximately two-four weeks following their Botox injection. This is done regardless if patients are exhibiting symptoms of urinary retention. Patients with an elevated PVR are treated with CISC if they are symptomatic.

Nevertheless, many studies suggest that patients are accurately able to self-identify symptoms of urinary retention, and treating asymptomatic urinary retention may not be necessary.

The investigators aim to describe how many patients with PVR >200mL had symptoms following intravesical injection of Botox for OAB.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

All patients who underwent onabotulinumtoxinA injections for overactive bladder by one of four fellowship trained female pelvic medicine and reconstructive surgeons at TriHealth between October 1, 2015 and October 1, 2019. These patients will be identified by CPT codes recorded in the EPIC electronic medical record.

Description

Inclusion Criteria:

  • OnabotulinumtoxinA injections in the bladder for overactive bladder
  • Completed a post injection appointment at which time PVR was collected (approximately 10 to 28 days following Botox injection)
  • Age >18
  • English speaking

Exclusion Criteria:

  • OnabotulinumtoxinA injection for any other cause than overactive bladder
  • Patients requiring self-catheterization at baseline
  • Failure to complete a postoperative appointment within 4 weeks of Botox injection

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 8, 2019

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
