September 24, 2018 updated by: Kang Su Cho, Gangnam Severance Hospital

What is the Most Effective Local Anesthesia for Prostate-stained Ultrasonography-guided Biopsy in PPB and PNB?: A Single Center, Prospective, Randomized, Double Arm Study

This study assesses differences in the effects of pelvic plexus block and periprostatic nerve block among various anesthetic methods that reduce the pain caused by prostate biopsy.

Study Overview

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.

Detailed Description

Recently, various types of local anesthetic methods have been attempted to reduce biopsy-related pain leading to changes in the type of anesthetic agents and site of injection. Of these anesthetics and combinations, pelvic plexus block and periprostatic nerve block seem to be the very effective way to control prostate biopsy-related pain. However, few studies have compared these two methods.

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.

Ages Eligible for Study

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • abnormal prostate finding on digital rectal examination
  • serum PSA level of > 2.5 ng/mL
  • Transrectal ultrasonographic abnormal lesion

Exclusion Criteria:

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Pelvic plexus block
The injections of 2.5 mL of 2% lidocaine were made to the pelvic neurovascular plexus located at the end of the seminal vesicle under Doppler US guidance on each side
Procedure: Pelvic plexus block
Injections of 2.5 mL of 2% lidocaine were made to the pelvic neurovascular plexus located at the end of the seminal vesicle under Doppler US guidance on each side
Active Comparator: Periprostatic nerve block
The injections of 2.5 mL of 2% lidocaine were made to the neurovascular bundles at the junction of the prostate-bladder-seminal vesicle.
Procedure: Periprostatic nerve block
Injections of 2.5 mL of 2% lidocaine were made to the neurovascular bundles at the junction of the prostate-bladder-seminal vesicle on each side.

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-1
Time Frame: day 7~14
Visual analog scale (0-10) during anesthesia procedure higher values represent a worse outcome.
day 7~14
Visual analog scale-2
Time Frame: day 7~14
Visual analog scale (0-10) at insertion of ultrasound probe higher values represent a worse outcome.
day 7~14
Visual analog scale-3
Time Frame: day 7~14
Visual analog scale (0-10) during biopsy procedure higher values represent a worse outcome.
day 7~14
Visual analog scale-4
Time Frame: day 7~14
Visual analog scale (0-10) at 15 min after the biopsy procedure higher values represent a worse outcome.
day 7~14

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
Rate of Complication
Time Frame: day 14~28
Complications after biopsy
day 14~28
Procedure time
Time Frame: day 7~14
Total time taken for prostate biopsy

Primary Completion (Anticipated)

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.
