Your Nephrostomy Catheter Change Appointment

This information will help you keep track of your nephrostomy catheter change appointment and help you understand when you need to call the Interventional Radiology Department. For more about how to care for your biliary catheter, review the information in Caring for Your Nephrostomy Catheter.

Scheduling Your Catheter Change Appointment

If that’s not possible, or if you need to change your appointment, please call 212-639-7946 at least 3 weeks before the date you would like to come in for your catheter change. To avoid wait times at the hospital, try to schedule your appointment as close to 8:00 am as possible.

Nephrostomy catheters are usually changed without sedation (medication to make you sleepy). You may have a little discomfort for a few minutes, but most people don’t find the procedure painful. If you do not have sedation, you can leave once your procedure is finished.

If you feel you need sedation for your catheter change, tell the person scheduling your appointment. If you will receive sedation, you will need to visit the pre-procedure area before your appointment. You will spend at least 4 hours at the hospital on the day of your procedure, and you will need a responsible adult to take you home afterward.
