This randomized controlled trial aims to investigate the impact of Virtual Reality (VR) as a non-pharmacological distraction method on patient-reported pain and anxiety during the removal of ureteral double-J (DJ) stents. Despite being a standard urological procedure, stent removal is often reported by patients to be a source of significant anxiety and procedure-related pain. By utilizing a standardized distraction environment via VR goggles, this study evaluates whether this intervention can effectively modulate the patient's perception of the procedure. The primary outcomes are measured using the State-Trait Anxiety Inventory (STAI) to assess psychological anxiety and the Visual Analog Scale (VAS) to quantify the intensity of pain experienced throughout the stent removal process.
The removal of ureteral double-J (DJ) stents is an essential procedure in urological practice. However, many patients express concerns regarding the potential for procedural pain, discomfort, and underlying anxiety, which can complicate the clinical experience. While various analgesic and anxiolytic strategies exist, there is a growing clinical imperative to evaluate effective, non-invasive, and non-pharmacological interventions to enhance patient comfort.
This prospective, randomized, interventional study will recruit patients scheduled for routine DJ stent removal. The study will allocate participants into an experimental group (receiving VR distraction during the procedure) and a control group (undergoing standard care). The VR intervention consists of immersive visual and auditory stimulation designed to divert the patient's attention from the invasive nature of the procedure.
The study will employ a longitudinal assessment approach:
By integrating virtual reality into the clinical workflow, this research aims to provide evidence-based insights into improving patient experience, potentially reducing the need for pharmaceutical pain management, and standardizing comfort protocols for outpatient urological interventions.

State-Trait Anxiety Inventory (STAI) Score
Evaluation of patient anxiety levels using the State-Trait Anxiety Inventory (STAI), comprising the State Anxiety (STAI-S) and Trait Anxiety (STAI-T) subscales. Both STAI-S and STAI-T are administered prior to the procedure, whereas only the STAI-S is administered following the procedure. Each subscale yields a score ranging from 20 to 80, where higher scores indicate greater severity of anxiety and lower scores indicate lower levels of anxiety.
Time frame: Ten minutes before the procedure and ten minutes after the procedure
Visual Analog Scale (VAS) Pain Score
Evaluation of patient pain intensity experienced during the procedure, assessed using the Visual Analog Scale (VAS) administered after the procedure. The scale ranges from 0 to 10, where higher scores indicate greater pain severity (worse outcomes) and lower scores indicate less pain or no pain (better outcomes).
Time frame: Ten minutes after the procedure
Plan to share: No
Start is estimated for Sep 2026; primary completion for Feb 2027, 5 months later.
Of 3,734 non-industry interventional studies with no phase under Pain, half reached primary completion within 10 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 23. This study's planned 5 months is below that.
Counting every sponsor, half of 3,833 studies reached it within 10 months; a quarter within 4 and three quarters within 23.
