This study aims to assess the use of primary X-ray beam collimation during ureteroscopy and its effect on patient radiation dose.
Methods:
A retrospective review of images and radiation doses of patients undergoing ureteroscopy.
Results:
The use of primary X-ray beam collimation during ureteroscopy is associated with lower radiation doses to the patient. Only 3% of images had evidence of collimation.
