To retrospectively investigate scatter radiation (SCR) exposure among staff in the endourology operating theatre.
During surgeries under fluoroscopic guidance, five professional groups (urological surgeon [US], surgical nurse [SN], assistant surgical nurse [ASN], anaesthetist [A], and anaesthesia care [AC]) wore real-time dosimeters (Philips DoseAware System) on their head and chest over lead aprons between July 2023 and February 2024. The SCR data were analysed and correlated with procedural and patient factors.
In total, 249 procedures were performed, including 86 retrograde intrarenal surgeries and 10 percutaneous nephrolithotomies. Median SCR exposure was 38.81, 17.20, 7.71, 11.58, 0.63, 0.23, 0.12, and 0.15 Microsievert (µSv) for US chest (USC), US head (USH), SN chest (SNC), SN head (SNH), A chest (AC), AC chest (ACC), ASN chest (ASNC), and ASN head (ASNH), respectively. There was a significant correlation between DAP and SCR doses detected by USC, USH, SNC, SNH, AC, and ACC dosimeters ( < 0.05). The median chest-to-eye conversion factor (CECF) was 2.11 for the US and 0.71 for the SN.
This study, using real-time dosimetry, is among the first to assess staff occupational SCR exposure in endourology. It highlights a substantial SCR exposure, indicating an occupational health hazard that warrants further investigation.
回顾性调查泌尿外科手术室工作人员的散射辐射（SCR）暴露情况。
在2023年7月至2024年2月期间，五组专业人员（泌尿外科医生[US]、手术护士[SN]、助理手术护士[ASN]、麻醉医生[A]和麻醉护理[AC]）在荧光透视引导下进行手术时，在铅衣外的头部和胸部佩戴实时剂量仪（飞利浦剂量感知系统）。对SCR数据进行分析，并与手术和患者因素相关联。
共进行了249例手术，包括86例逆行肾内手术和10例经皮肾镜取石术。US胸部（USC）、US头部（USH）、SN胸部（SNC）、SN头部（SNH）、A胸部（AC）、AC胸部（ACC）、ASN胸部（ASNC）和ASN头部（ASNH）的SCR暴露中位数分别为38.81、17.20、7.71、11.58、0.63、0.23、0.12和0.15微西弗（µSv）。USC、USH、SNC、SNH、AC和ACC剂量仪检测到的DAP与SCR剂量之间存在显著相关性（<0.05）。US的胸部到眼睛转换因子（CECF）中位数为2.11，SN为0.71。
本研究采用实时剂量测定法，是首批评估泌尿外科工作人员职业性SCR暴露的研究之一。它突出了大量的SCR暴露，表明这是一种需要进一步调查的职业健康危害。
