About this study

Official title: Optimal Intravesical Lidocaine Volume for Pain Relief During Office Intra-detrusor Onabotulinum Toxin a Injections: a Prospective Randomized Superiority Trial

The purpose of our study is to evaluate the efficacy and safety of different volumes of bladder-numbing medication for pain relief at the time of office bladder Botox injections. This is a randomized prospective, double-blind superiority trial comparing 200 ml 2% lidocaine versus 30 ml 2% lidocaine for office Botox injections.

Read the detailed description

The volume of 2% intravesical lidocaine solution and efficacy for pain relief at the time of office intradetrusor Botox A injection has not been well studied. Studies evaluating intravesical lidocaine show that it is not sufficiently absorbed by human bladders to achieve serum toxicity levels and only provides superficial local anesthetic effect. Experts agree that intravesical local anesthetic can be given in the office, with approximately 30 to 40 mL of 2% lidocaine instilled via catheter into the bladder for about 20 minutes before injection. However, there is little evidence regarding this strategy, and future research would help standardize recommendations.

The purpose of our study is to evaluate the efficacy and safety of higher volume pre-procedure intravesical lidocaine solution for pain at the time of intradetrusor office Botox injections. This is a randomized prospective, double-blind superiority trial comparing 200 ml 2% lidocaine versus 30 ml 2% lidocaine for office Botox injections.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Visual Analog Scale (VAS)

    1. Determine the efficacy of pain relief via the Visual Analog Scale (VAS, scored 0-100 on 100 mm scale with 0 indicating no pain and 100 indicating the worst pain possible) in women randomized to 200 ml 2% lidocaine without epinephrine versus 30 ml 2% lidocaine without epinephrine prior to office intravesical onabotulinum toxin A (Botox) injections i. Perceived maximum VAS during the procedure and post-procedure ii. Superiority limit 20 mm on 100 mm VAS scale

    Measured: on day of enrollment and procedure

Secondary outcomes (7)
  1. Patient Global Impression of Severity (PGI-S)

    Likert scale describing current severity of urinary tract condition: 1. Normal, 2. Mild, 3. Moderate, 4. Severe; higher scores indicate worse symptoms

    Measured: through study completion, an average of 1 year

  2. Overactive Bladder Satisfaction with Treatment Questionnaire (OAB-Sat-q)

    An 11-item questionnaire that assesses patient satisfaction with their overactive bladder (OAB) treatment. It includes three sub-scales (satisfaction, side effects, and endorsement) and two single-item assessments (convenience and preference). Scores range from 0-100, higher scores indicate higher satisfaction with treatment. Used to assess treatment satisfaction over time.

    Measured: This will be assessed pre and post-intervention for all participants through study completion, an average of 1 year

  3. Patient Satisfaction Questionnaire Short-Form (PSQ-18)

    An 8-item question assessing satisfaction with medical care experience, measured on a Likert scale with 1 "Strongly agree" and 5 "Strongly disagree", for questions 1-3, 5-6, and 8 lower scores indicate higher satisfaction. For questions 4 and 7 lower scores indicate dissatisfaction.

    Measured: through study completion, an average of 1 year

  4. Patient Global Impression of Improvement (PGI-I)

    7-point Likert scale with 1 indicating "Very much better" and 7 indicating "Very much worse", lower scores indicate more improvement

    Measured: through study completion, an average of 1 year

  5. Bladder diary

    3-day bladder diary with objective patient reported data reporting voids per day, frequency between voids (measured in minutes or hours), episodes of incontinence per day

    Measured: through study completion, an average of 1 year

  6. Post-void residual volume

    Measure voided volume and obtain post-void residual volume either by bladder scan or straight catheterization in the office at 2-week follow up appointment (or additional time points if indicated) following bladder Botox injection

    Measured: through study completion, an average of 1 year

  7. Adverse events

    All adverse events will be recorded and tracked, including urinary tract infection, urinary retention, persistent hematuria, or additional suspected procedural related complications

    Measured: through study completion, an average of 1 year

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 19 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
