Abstract

PURPOSE: Fluoroscopy is valuable in modern endourology. We present the results of a survey where compliance to radiation safety measures was tested according to surgical exposure, and level of understanding of the radiation rules and risks associated with it.

METHODS: A 52-item, anonymous questionnaire, structured by 6 ESUT/EULIS experts was distributed at 3 different endourological meetings during 2017-2018. Main aim was to evaluate level of knowledge on radiation physics and the protective measures taken against radiation exposure by participants. Fisher's exact test, Kruskal-Wallis test and ROC curve were used for statistical analysis.

RESULTS: 211 responses were evaluated. Number of correct answers (median 7.00) differed significantly according to age (p = 0.001), working position (p = 0.005), working field (p < 0.001), number of semirigid (p < 0.001)/flexible URS (p < 0.001) and PNL (p < 0.001) performed per year. Physicians aged 50-60 years, consultants, academics and those who performed more procedures achieved higher scores. In our study 51.7% of responders used shields in the operating room, 89.6% wore lead aprons, 84.4% thyroid shields, while glasses and gloves were used by 14.7% and 8.1%, respectively. Age, working field and number of correct answers did not affect significantly the use of protection in contrast with endourology fellowship training, working position and lessons on radiation. Interestingly, residents, untrained endourologists and those who were provided with lessons on radiation were more compliant.

CONCLUSIONS: Our study revealed that majority of modern urologists advocate radiation protection during endourology practice. Senior consultants and academic urologists performing a high volume of procedures seem to understand physics and rules of radiation use.
