A Novel Application of 2% Lidocaine Injection for Male Rigid cycstoscopy-a Patient-blinded Randomised Trial

April 22, 2024 updated by: Cheng Shunhua, Second Xiangya Hospital of Central South University
The goal of this clinical trial is to learn about a novel application of lidocaine injection in male patients who needs rigid cycstoscopy test. The main question it aims to answer is:Does New Application of Lidocaine Liquid Provide Pain Relief for Patients During Cystoscopy? Before the cycstoscopy,Participants will be randomly divided into three different anesthesia mode groups,namely are Group A (intraurethral lidocaine gel alone), Group B (intraurethral lidocaine gel + lidocaine 2% injection), and Group C (intraurethral lidocaine gel + liquid paraffinl).Patients only need to prepare and cooperate according to routine surgical operations，which is group B or group C.

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

The primary objective of this clinical trial is to investigate the efficacy of a novel application of lidocaine injection in alleviating pain for male patients undergoing rigid cystoscopy procedures. Rigid cystoscopy is a common diagnostic examination used to visualize the interior of the bladder and urethra. However, it can be associated with discomfort and pain for patients.

The central question driving this study is whether the new application of lidocaine liquid can provide effective pain relief during cystoscopy. To address this question, participants will be randomly assigned to one of three anesthesia mode groups: Group A, which will receive intraurethral lidocaine gel alone; Group B, which will receive intraurethral lidocaine gel along with lidocaine 2% injection; and Group C, which will receive intraurethral lidocaine gel along with liquid paraffin.

Those assigned to Group B or Group C will only need to prepare and cooperate according to routine surgical operations. This standardizes the pre-procedural preparation process across the study groups, ensuring consistency in the approach to anesthesia administration.

By comparing the pain levels experienced by patients in each group during cystoscopy, the study aims to determine the effectiveness of the new lidocaine application method in providing pain relief. This information will be crucial in improving the patient experience during cystoscopy procedures and potentially optimizing anesthesia protocols for future clinical practice.

Interventional

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.

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
Access the pain score using the Visual Analogue Scale (VAS)
Time Frame: The procedure was evaluated using the visual analogue scale immediately afterward (referred to as "during the procedure" for the study's purposes) and again five minutes later.
Access the pain score assessed using the Visual Analogue Scale (VAS) during the procedure

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.
