What is a catheter?
A catheter is a simply a thin tube which is inserted into your body. These tubes allow medication and fluids to be injected into your body without needing a needle to be inserted each time. There are many different kinds of catheters, each with a specific use. Some catheters can actually be implanted under your skin so that no part of the tube is visible from the outside. The type of catheter you will receive will be discussed with you at length prior to the procedure.
How long does the catheter stay in?
The length of time your catheter stays in is dependent on why it was inserted in the first place. The length of time will be discussed with you prior to starting the procedure. Some stay in for a couple of days, others stay in for months.
Can I go home after the procedure?
For most procedures you will be able to leave soon after completion. Occasionally the radiologist will want to monitor you for an hour or two. This monitoring is to ensure that it is safe for you to go home. If you have any problems after going home you will be given a number to call for assistance.
