Audiovisual Stimulus During Urodynamics

Many women have the need to run to the restroom frequently during the night and day, a condition called "overactive bladder". Embarrassing urinary leakage is also commonly associated with these symptoms. The investigators believe the primary cause in most cases is the bladder muscle contracting too frequently but are still not sure exactly why this happens and if it is triggered by factors in the environment. When bladder testing using pressure catheters ("urodynamics") is done these bladder contractions are often not picked up, even in women with overactive bladder. This may be partly due to the unnatural environment in which the testing is done without the presence of the usual visual or audible triggers, such as running water or seeing a toilet. The investigators propose adding an audiovisual stimulant to the usual bladder testing to see if this makes it more likely for bladder contractions to happen. One group of patients would have the usual bladder testing as part of their normal care. The other group would receive the normal care in addition to hearing a water fountain in the room and watching a video of things that may trigger overactive bladder symptoms; seeing public restroom signs in a mall, a toilet bowl being lowered and a kitchen sink with water running over dishes. The suspicion is that the proportion of patients in whom bladder contractions are seen will be higher for those with audiovisual triggers compared to those with the usual care. Women with overactive bladder or leakage with urge who are sent for urodynamics by their doctor will be asked if they wish to participate in the study.
