Running water sounds during a bladder function (urodynamic) test

Impact of Running Water Sound on Anxiety and Urodynamic Parameters: A Multi-Center Randomized Controlled Trial

NA · Princess Margaret Hospital, Hong Kong · NCT07451548

This study tests whether listening to recorded running water during a urodynamic (bladder function) test helps Chinese women with LUTS feel calmer and empty their bladder more easily.

What this trial studies

Participants are Chinese women scheduled for a urodynamic study who can read traditional Chinese and give informed consent. They will be randomly assigned to either listen to recorded running water during the test or undergo the test as usual without added sound. Anxiety levels will be recorded before, during, and after the procedure using simple visual scales, and urodynamic parameters such as maximum flow rate will be measured. Results will compare subjective anxiety and objective test measures between the two groups to see if the auditory intervention changes patient experience or test outcomes.

Who should consider this trial

Good fit: Chinese women aged 18–90 scheduled for a urodynamic study who can read traditional Chinese, provide written consent, and do not have hearing loss, severe cognitive impairment, or psychiatric conditions that would interfere with anxiety scoring.

Not a fit: Patients with hearing impairment, severe cognitive or psychiatric disorders that affect anxiety reporting, or those who cannot read traditional Chinese are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the intervention could reduce test-related anxiety and improve bladder emptying and the quality of urodynamic measurements, making the procedure more comfortable and reliable.

How similar studies have performed: Previous small studies and anecdotal reports suggest running water can help with voiding and reduce anxiety, but randomized data in urodynamic settings are limited.
