Although it seems like a grammatical mistake, the question truly is "what is urodynamics?" That is to say: what is urodynamics testing? The term refers to a certain test we use to determine how fluid moves through your bladder (hence: uro-dynamics).
From an administrative standpoint, it's important for you to know that the test takes about an hour and a half. That time can vary by as much as half an hour, but 90 minutes is the safest estimate to give if you are arranging transportation or blocking off time in your schedule.
It is also important to note that the test is non-surgical and does not require anesthesia. As such, you will not need to be driven to and from the appointment if you are otherwise capable of driving yourself. From a clinical standpoint, you should know that no formal preparation is required prior to the test. You do not need to fast prior to the appointment, and you do not need to observe any dietary restrictions.
However, to ensure that your test begins on time and proceeds promptly, we ask that you come to your appointment with a comfortably full bladder. If you arrive early for your appointment and urgently need to empty your bladder, notify the receptionist and discuss with her whether you should wait or use the restroom right away and drink more when you are finished.
Come back later this week for another instillation in our current series, “PFI Testing,” in which we break down the various tests performed in the PFI office in clinical terms and in layman’s terms.
