Editing Functional: Urodynamics (section)

== Conducting UDS ==

* Many patients undergoing UDS will have been started on medications that can affect bladder function. The clinician should decide in advance what information is desired and whether the study should be done on or off medication.
** If the goal of the study is to determine the therapeutic effect of a medication, UDS should be done with the patient on a regular dosing schedule for that medication.
** If the medication was started empirically to treat symptoms and the goal of the urodynamic test is to uncover the cause of those symptoms, consideration can be given to discontinuing the medication before testing because this may give the highest yield.
* '''UDS is performed in an “unnatural setting” and therefore does not always duplicate real-life situations.'''
** '''Failure to record an abnormality does not always rule out its existence''' (e.g. failure to demonstrate detrusor overactivity (DO) in a patient with urgency incontinence).
** '''Not all UDS observations are clinically significant.'''
