Local Anesthesia Before Bulkamid Injection (LAB)

May 13, 2025 updated by: Medstar Health Research Institute

Post-procedural Pain Associated With Periurethral Block at Time of Bulkamid Injection for SUI: a Randomized Controlled Trial

While recommended pre-anesthesia for polyacylamide hydrogel (PAHG, Bulkamid) injections for stress urinary incontinence and intrinsic sphincter deficiency can include intraurethral anesthetic gel with or without periurethral block, there is no existing literature to guide choice of anesthesia. This is a single-blinded randomized control trial to evaluate post-procedure pain with choice of anesthesia before PAHG injection.

Conditions

Conditions

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Visual analog scale (VAS) for pain
Time Frame: Ascertained at end of procedure (withdrawal of cystoscope)
Visual analog scale for pain uses a scale from 0-10 corresponding to reported pain levels with 0 indicating no pain and 10 indicating most severe pain possible
Ascertained at end of procedure (withdrawal of cystoscope)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Duration of procedure
Time Frame: Ascertained at end of procedure (within 5 minutes of withdrawal of cystoscope)
in seconds
Ascertained at end of procedure (within 5 minutes of withdrawal of cystoscope)
Incomplete bladder emptying
Time Frame: Ascertained on day-of-procedure (within 1 hour of withdrawal of cystoscope)

Ascertained on day-of-procedure (within 1 hour of withdrawal of cystoscope)
Need for re-injection of PAHG
Time Frame: Assessed at follow-up 2 weeks post-procedure

Assessed at follow-up 2 weeks post-procedure
International Consultation on Incontinence Questionnaire for Urinary Incontinence (ICIQ-UI)
Time Frame: Assessed at baseline and at two-week and twelve-week follow-up visit
3 items on frequency/quantity of leakage and impact on quality on life (range 0-21 with lower score indicating lower severity of incontinence symptoms and higher score indicating higher severity of incontinence symptoms)

1 item on relative change in symptoms following treatment (range 1-7 with lower score indicating greater improvement in incontinence symptoms following intervention and higher score indicating lower improvement in incontinence following intervention)
Assessed at two-week and twelve-week follow-up visit
