On February 6, 2018, the European Atomic Energy Community reduced the annual equivalent dose limit for the lens from 150 to 20 mSv/year, because of its association with cataracts at low radiation doses. Our aim was to estimate the radiation doses received by the lens during endourologic procedures that require fluoroscopy. Multicenter study including prospective data of annual eye dosimeters between 2017 and 2020. Four endourologists used an eye dosimeter in endourologic procedures that require fluoroscopy (ureteroscopy, retrograde intrarenal surgery, and percutaneous nephrolithotomy). Surgeons 1 and 2 wore leaded glasses; surgeon 1 also used the as low as reasonably achievable (ALARA) protocol. Descriptive statistical analysis using SPSS 25.0 was conducted. Surgeons 1, 2, 3, and 4 performed a median of 159, 586, 102, and 129 endourologic procedures per year, respectively, for a total of 641, 2340, 413, and 350 procedures between 2017 and 2020. The median annual dose of lens radiation exposure was 0.16, 1.18, 3.79, and 1.42 mSv per year, respectively, which corresponds to 0.001, 0.009, 0.024, and 0.012 mSv per procedure. The two surgeons who used leaded glasses registered a lower radiation dose per procedure (0.001 0.027). Similarly, the urologist who used the ALARA protocol registered the lowest lens radiation dose compared with the three surgeons who did not use it (0.001 0.023). The endourologists who participated in this study effectively comply with current guidelines on radiation exposure to the lens. Registered eye lens radiation does not seem to be related to the number of procedures but rather to the use of leaded glasses and the ALARA protocol.
2018 年 2 月 6 日，由于低剂量辐射与白内障有关，欧洲原子能共同体将晶状体的年当量剂量限值从 150 降低到 20 mSv/年。我们的目的是估计需要透视的腔内泌尿外科手术中晶状体所接受的辐射剂量。
这是一项包括 2017 年至 2020 年期间年度眼剂量计的前瞻性数据的多中心研究。四位腔内泌尿外科医生在需要透视的腔内泌尿外科手术中使用眼剂量计（输尿管镜检查术、逆行性肾内手术和经皮肾镜取石术）。外科医生 1 和 2 佩戴了铅眼镜；外科医生 1 还使用了尽可能低的合理可行（ALARA）方案。使用 SPSS 25.0 进行描述性统计分析。
外科医生 1、2、3 和 4 每年分别进行中位数为 159、586、102 和 129 次腔内泌尿外科手术，总计 2017 年至 2020 年期间共进行 641、2340、413 和 350 次手术。晶状体辐射暴露的年平均剂量分别为每年 0.16、1.18、3.79 和 1.42 mSv，相当于每次手术 0.001、0.009、0.024 和 0.012 mSv。使用铅眼镜的两位外科医生记录的每次手术辐射剂量较低（0.001 0.027）。同样，使用 ALARA 方案的泌尿科医生与未使用该方案的三位外科医生相比，晶状体辐射剂量最低（0.001 0.023）。
参与这项研究的腔内泌尿外科医生有效遵守了目前关于晶状体辐射暴露的指南。登记的眼晶状体辐射剂量似乎与手术数量无关，而与使用铅眼镜和 ALARA 方案有关。
