  1. Radiation risk to the urologist during endourologic procedures, and a new shield that reduces exposure.

    Article - En anglais


    With the increasing use of endourologic procedures to diagnose and treat urologic problems, the urologist's exposure to radiation from fluoroscopy becomes an important safety consideration.

    Although collimation of the x-ray beam generally prevents direct radiation exposure by the urologist, the patient absorbs radiation during the procedure and becomes a secondary source of exposure through radiation scatter.


    We measured radiation exposure to the urologist during endourologic procedures using standard body shields and thyroid collars.

    We repeated our surveys using a newly designed urologic surgery radiation shield.


    We found dose rates to the urologist of up to 1100 mrem per hour of flouroscopy time.

    The maximum yearly whole-body exposure as recommended by the National Council on Radiation Protection is 5000 mrem, or 5 rem.


    Urologists should be cognizant of this radiation risk, and the concepts of time, distance, and shielding are critically important to know in efforts to reduce radiation exposure.

    We introduce a newly designed fluoroscopic drape which reduces the radiation dosage to the urologist from scatter nearly 70-fold.

    We found this shield to be very practical and easy to use, and we offer it as an effective safeguard against secondary radiation exposure.
