What is going to happen?
You will lie on your back. Control x-rays will be done to exclude duct stones. A catheter will be inserted into the opening and contrast injected to opacify the duct. Several x-rays from different positions will be taken. After the procedure you will be given lemon juice to determine if the stimulus results in clearance of contrast from the duct.
Is it painful?
You may experience some discomfort during contrast injection as the duct dilates.
Do I need a booking?
It is preferable to make a booking to alleviate any delay for the patient.
