Oh my dear friend, I hope this turns out to be far less ominous than it is sounding.
I have at LEAST one CT per year to monitor my "Thoracic Aortic Aneurysm", and yes, I am intimately familiar with an cystoscope. Pray that you never have to endure a "Urodynamics Test", which for me at least, was THE most unpleasant and invasive thing.
I do so hope and pray that you are not stage IV anything
