Ultrasound: Each facility may have slightly different instructions on this. In general avoid drinking anything. It may be OK to take a few sips wih medication if you need to. Call your office and see what their particular instructions are.

It depends: Whether a urinary catheter is needed depends on the length of the operation as well as surgeon preference. Sometimes a catheter is placed for the operation only and removed before a patient wakes up from anesthesia. If the operation is uncomplicated and only involves taking out the gallbladder, then this is usually short enough to not need a catheter.
