目标。非增强螺旋计算机断层扫描 (UHCT) 正迅速成为评估成人疑似肾绞痛的首选成像方式；然而，此前尚未出版过关于青少年群体使用该药物的系列文章。我们评估了 UHCT 在评估该年龄组疑似肾绞痛方面的效用。方法。 17 名年龄在 8 岁至 18 岁之间（平均 14.7 岁）的患者到四家医院的急诊科就诊，以评估疑似肾绞痛。所有患者在初步评估后立即接受 UHCT 研究。使用 5 毫米的切片厚度，从 T-12 椎骨的中点到膀胱基底下方的点进行单次螺旋采集。胶片由机构放射科医生审查，并对结果进行量化。结果。在接受评估的17名患者中，8名患者未发现异常。 7 名患者体内出现结石，随后接受了适当的治疗。一名患者没有看到结石，但次要迹象表明最近有结石排出。最后一位患者没有结石；然而，注意到明显的双侧输尿管肾积水，需要进一步评估。仅在 1 名患者中发现单个静脉石，并且没有研究无法诊断。结论。 UHCT 是一种安全、快速的测试，用于评估青少年疑似肾绞痛。它对肾脏和输尿管结石具有高度敏感性和特异性，更重要的是，可以实现替代病理学的可视化。此外，可以看到次要迹象，有助于确定阻塞，如果没有看到结石，也很有帮助。静脉石可以模拟石头，在青春期很少见。我们认为 UHCT 可以快速分类和定位结石，应推荐作为评估疑似肾绞痛青少年的主要诊断方式。泌尿学 57: 342-546, 2001。(C) 2001，爱思唯尔科学公司。
Objectives. Unenhanced helical computed tomography (UHCT) is rapidly becoming the preferred imaging modality for the evaluation of suspected renal colic in the adult population; however, a series addressing its use in the adolescent population has not been previously published. We assessed the utility of UHCT in the evaluation of suspected renal colic in this age group.Methods. Seventeen patients between the ages of 8 and 18 years (mean 14.7) presented to the emergency departments of four hospitals for evaluation of suspected renal colic. All patients were studied with UHCT immediately after initial evaluation. A single helical acquisition was performed from the midpoint of T-12 vertebra to a point below the bladder base, using a slice thickness of 5 mm. Films were reviewed by the institutional radiologist, and results were quantified.Results. Of the 17 patients who underwent evaluation, no abnormality was detected in 8 patients. A stone was localized in 7 patients who were then appropriately treated. One patient had no stone visualized, but secondary signs suggested a recently passed stone. The final patient had no stone; however, marked bilateral hydroureteronephrosis was noted that led to further evaluation. A single phlebolith was seen in only 1 patient, and no study was nondiagnostic.Conclusions. UHCT is a safe, rapidly performed test for the evaluation of suspected renal colic in adolescents. it is highly sensitive and specific for renal and ureteral calculi and, more importantly, allows visualization of alternate pathology. In addition, secondary signs are seen that aid in determining obstruction and are helpful if no stone is visualized. Phleboliths, which can simulate a stone, are rarely seen in adolescence. We believe UHCT allows for rapid triage and localization of stones and should be recommended as the primary diagnostic modality for the evaluation of adolescents with suspected renal colic.
