The aim was to compare the findings of non-contrast computerized tomography (NCCT) evaluated by urology specialists with the findings of experienced radiologists, who are accepted as a standard reference for patients who present with acute flank pain.
Five hundred patients evaluated with NCCT were included in the study. The NCCT images of these patients were evaluated by both radiologists and urology specialists in terms of the presence of calculus, size of calculus, the location of calculus, the presence of hydronephrosis, and pathologies other than calculus, and the results were compared.
The evaluations of urology specialists and standard reference radiology specialists are consistent with each other in terms of the presence of calculus (kappa [κ]: 0.904), categorical stone size (κ: 0.81), the location of calculus (κ: 0.88), and hydronephrosis (κ: 0.94). However, the evaluations of urology specialists in detecting pathologies other than calculus, which may cause acute flank pain or accompany renal colic, were found to be inadequate (κ: 0.37). The false-negative rate of detecting pathologies outside of the urinary system by the urology specialists is calculated as 0.86.
Although the urology specialists can evaluate the findings related to calculus sufficiently with NCCT, they may not discover pathologies outside of the urinary system.
本研究旨在比较泌尿外科专家对非增强计算机断层扫描（NCCT）结果的评估与经验丰富的放射科医生的评估结果，放射科医生的评估结果被视为急性腰痛患者的标准参考。
本研究纳入了500例接受NCCT检查的患者。放射科医生和泌尿外科专家对这些患者的NCCT图像进行了评估，内容包括结石的存在、结石大小、结石位置、肾积水的存在以及除结石以外的其他病变，并对结果进行了比较。
泌尿外科专家和标准参考放射科专家在结石存在情况（kappa[κ]：0.904）、结石分类大小（κ：0.81）、结石位置（κ：0.88）和肾积水（κ：0.94）方面的评估结果相互一致。然而，发现泌尿外科专家在检测可能导致急性腰痛或伴随肾绞痛的除结石以外的其他病变方面评估不足（κ：0.37）。泌尿外科专家检测泌尿系统以外病变的假阴性率计算为0.86。
虽然泌尿外科专家能够通过NCCT充分评估与结石相关的结果，但他们可能无法发现泌尿系统以外的病变。
