RCT on Running Water Sound During Urodynamic

NCT07451548 | Recruiting

• 1 other identifier: water sound in urodynamic
• Study Type: interventional
• Target: 240
• Locations: 1 country
• Sites: 2

Brief Summary

This study aims to see if listening to recorded running water sounds during a bladder function test (urodynamic study) helps patients feel calmer and makes it easier for them to empty their bladder during the test. Bladder tests can cause anxiety or discomfort, which sometimes affects results. Playing running water sounds may help patients relax and improve their experience, based on earlier research. Participants will be randomly placed into one of two groups. One group will listens to running water sounds during the test while the other group will have the test done in the usual way without additional auditory intervention. Participants rate their anxiety before, during, and after the test using simple scales. Parameters of the test will be recorded for analysis.

Conditions

Lower Urinary Tract Symptoms (LUTS)

Keywords

Urodynamics; Anxiety; Running water sound; Maximum flow rate

Outcome Measures

Primary Outcomes (1)

• Maximum urinary flow rate (Qmax) measured by urodynamic pressure-flow study

  Maximum urinary flow rate (Qmax), defined as the peak flow rate during voluntary voiding with an indwelling catheter in place, measured in milliliters per second (mL/s) using standard urodynamic equipment. This parameter reflects bladder outlet function and is recorded automatically by the urodynamic system.

  During the pressure-flow study phase of the urodynamic procedure

Secondary Outcomes (7)

• Anxiety level before urodynamic procedure measured by Visual Analogue Scale (VAS)

  Immediately before the start of the urodynamic procedure

• Anxiety level during pressure-flow study measured by Visual Analogue Scale (VAS)

  During the pressure-flow study phase of the urodynamic procedure

• Anxiety level within 15 minutes after urodynamic procedure measured by Visual Analogue Scale (VAS)

  Within 15 minutes after completion of the urodynamic procedure

• Detrusor pressure at maximum flow rate (PdetQmax) measured by urodynamic pressure-flow study

  During the pressure-flow study phase of the urodynamic procedure

• Proportion of participants able to micturate (void) during pressure-flow study phase

  During the pressure-flow study phase of the urodynamic procedure
