Renal colic is a common disease in Europe and a common cause of visit to the Emergency Department. Clinical diagnosis is usually confirmed by imaging modalities. Unenhanced computed tomography (CT) is considered the best diagnostic test due to its excellent accuracy detecting ureteral stones. However, ultrasound (US) should be considered as the primary imaging technique. It is a reproducible, non-invasive and non-expensive imaging technique, achieving accurate diagnosis in most cases without the need for radiation. Diagnosis is based on the presence of ureteral stones, but indirect findings such as the asymmetry or absence of ureteric jet, an increase of the resistive index or a colour Doppler twinkling artefact may help to suggest the diagnosis when the stone is not identified.
• Renal colic diagnosis is usually confirmed by imaging modalities. • Imaging diagnosis of renal colic is based on the detection of ureteral stones. • CT is the most accurate imaging technique to identify ureteral stones. • US allows correct diagnosis in most cases without using radiation. • US should be used as the first imaging modality in patients with renal colic.
肾绞痛在欧洲是一种常见疾病，也是急诊就诊的常见原因。临床诊断通常通过影像学检查来确诊。非增强计算机断层扫描（CT）因其检测输尿管结石的准确性极高，被认为是最佳诊断检查方法。然而，超声（US）应被视为主要的成像技术。它是一种可重复、无创且成本低廉的成像技术，在大多数情况下无需辐射即可实现准确诊断。诊断基于输尿管结石的存在，但当未发现结石时，诸如输尿管喷流不对称或缺失、阻力指数增加或彩色多普勒闪烁伪像等间接征象可能有助于提示诊断。
• 肾绞痛的诊断通常通过影像学检查来确诊。• 肾绞痛的影像学诊断基于输尿管结石的检测。• CT是识别输尿管结石最准确的成像技术。• US在大多数情况下无需使用辐射即可做出正确诊断。• US应作为肾绞痛患者的首选成像方式。
