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.
