SUFU 2020: Audio-Visual Stimuli in an Oral Hydration Study: Heightened Response in Overactive Bladder Participants

Scottsdale, AZ (UroToday.com) Kaitlyn Maddra presents their research on audio-visual stimulation triggering urgency in overactive bladder patients. They aimed to quantify the changes in sensation with a non-invasive hydration study. They grouped healthy and OAB patients based on ICIq-OAB survey. A 6 question survey on triggers was provided.

The study participants were given an oral hydration protocol (3 Fill). They drank 2 liters of Gatorade G2 during fill 1 and water during fills 2 and 3. A tablet-based meter was used to measure bladder sensation from 0-100%. At 50% sensation, a 3-minute video was watched showing different scenes with water.

The change in sensation was calculated and the results are in the table below.

Kaitlyn concludes that there is a correlation between running water with trigger survey.

A non-invasive hydration protocol can help in identifying environmental triggers, but more research is needed.

There was a suggestion from the audience to have patients bring images of own bathroom. Previous research has been done with the patient's own bathroom photo and looking at fMRI had higher activation patterns of bladder fullness.
