How:

  1. Empty your bladder 1 hour before the scan/treatment.

  1. Drink 300 ml of fluid within the next 15 minutes. (2 glasses in total)

  1. The scan/treatment will be made with a filled bladder.

  1. You may go to the toilet immediately after your appointment.

Why:

  • Fewer side effects

A filled bladder ensures that part of the bladder lies outside the radiation field. Additionally, a filled bladder pushes the small bowel away from the radiation field. This can help to reduce side effects.

  • Accuracy of the radiation treatments

Consistent bladder filling is important for the accuracy of radiation treatments.

If you have difficulty following these instructions, please discuss this with the radiotherapy technicians
