An interventional study of Standard Lighting and music in Lower Urinary Tract Symptoms, Urinary Incontinence and Voiding Dysfunction, sponsored by Baskent University Ankara Hospital. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-29.
Sponsored by Baskent University Ankara Hospital · Not applicable, Interventional, and Supportive care
This study is designed to evaluate the effects of environmental modifications, specifically music and lighting conditions, on anxiety in patients undergoing urodynamic study (UDS). Approximately 220 adult participants are planned to be randomly assigned to one of four intervention groups. Anxiety levels before and after the procedure will be assessed using the State-Trait Anxiety Inventory (STAI). The study aims to determine the independent and combined effects of music and lighting on patient anxiety during UDS.
Urodynamic study (UDS) is an important diagnostic procedure for evaluating lower urinary tract dysfunction. Because UDS requires urethral and rectal catheterization, many patients experience anxiety before and during the procedure. This study is designed to evaluate whether environmental modifications, including relaxing music and dim lighting, reduce anxiety during UDS.
Approximately 220 adult participants are planned to be enrolled and randomly assigned in a 1:1:1:1 ratio to one of four groups: standard lighting without music, standard lighting with music, dim lighting without music, and dim lighting with music. Anxiety will be assessed before and after the procedure using the State-Trait Anxiety Inventory (STAI). Secondary outcome measures will include heart rate and blood pressure changes. The study will evaluate the independent and combined effects of music and lighting using a 2 × 2 factorial design.
983 studies on the registry are indexed under Urinary Incontinence; 180 are open to participants now.
This study's enrollment of 220 is above the median of 66 across 739 interventional studies indexed under Urinary Incontinence.

Participants undergo urodynamic study under standard lighting without music.
Other: Standard Lighting
Participants undergo urodynamic study under standard lighting while listening to relaxing instrumental music.

Standard lighting (500 lux) during the urodynamic study.
Relaxing instrumental Zen-style music played during the urodynamic study.
Ambient lighting is reduced to approximately 50 lux throughout the urodynamic study to provide a dimly lit examination environment.
Change in State-Trait Anxiety Inventory (STAI) Score
The primary outcome is the change in State-Trait Anxiety Inventory (STAI) score from before to after the urodynamic study. The STAI is a validated questionnaire used to assess anxiety, with higher scores indicating greater anxiety. The change in score will be compared between the four intervention groups.
Time frame: Immediately before and immediately after the urodynamic study
Plan to share: No — Individual participant data will not be publicly shared because the study contains potentially identifiable clinical information. De-identified aggregate data may be available from the corresponding investigator upon reasonable request, subject to institutional and ethical approval.

Ran from Jul 2026 to primary completion in Sep 2026, 2 months.
Of 301 non-industry interventional studies with no phase under Urinary Incontinence, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 37. This study's 2 months is below that.
Counting every sponsor, half of 364 studies reached it within 15 months; a quarter within 7 and three quarters within 35.
