目的回顾性研究速尿对CT平扫肾髓质高密度显影的影响。材料与方法这项回顾性的单一机构研究符合HIPAA标准，并得到机构评审委员会的批准；免除了知情同意的要求。这项研究确定了289名无输尿管梗阻的连续患者(152名男性，137名女性；平均年龄59岁)，他们接受了CT尿路成像的平扫；其中178名患者在成像前没有接受静脉注射速尿，111名患者接受了。记录肾髓质高密度、肾结石和膀胱尿液衰减水平，并比较在成像前未接受速尿治疗的患者和使用χ2和未配对学生测试的患者之间的差异。结果在接受速尿治疗的111例患者中，肾髓质密度增高的发生率(27/111，24%)低于未接受速尿治疗的患者(79/178，44%，P=.001)。接受速尿治疗的患者(−0.1HU)与未接受治疗的患者(6.4HU，P<；.001)相比，膀胱尿液衰减较低。多因素Logistic回归模型显示肾髓质高密度影与未使用速尿(P=.002)、年轻(P<；.001)和肾结石(P=.047)独立相关。结论在平扫CT前应用速尿与肾髓质高密度影降低有关。
PurposeTo retrospectively investigate the effects of furosemide on the visualization of renal medullary hyperattenuation at unenhanced computed tomography (CT).Materials and MethodsThis retrospective single-institution study was HIPAA compliant and approved by the institutional review board; requirement for informed consent was waived. This study identified 289 consecutive patients (152 men, 137 women; mean age, 59 years) without ureteral obstruction who underwent unenhanced scanning as part of CT urography; of these, 178 patients did not receive intravenous furosemide prior to imaging and 111 did. The presence of renal medullary hyperattenuation, renal stones, and bladder urine attenuation levels were recorded and compared between patients who did not receive furosemide prior to imaging and those who did by using the χ2and unpaired Studentttests. A multiple logistic regression model was used to evaluate independent predictors of visualization of renal medullary hyperattenuation.ResultsRenal medullary hyperattenuation was seen less commonly in patients who received furosemide (27 of 111, 24%) than in those who did not receive furosemide prior to imaging (79 of 178, 44%,P= .001). Bladder urine attenuation was lower in patients who received furosemide (−0.1 HU) compared with those who did not (6.4 HU,P< .001). A multiple logistic regression model revealed independent associations between the visualization of renal medullary hyperattenuation and the absence of furosemide administration (P= .002), younger age (P< .001), and presence of renal stones (P= .047).ConclusionFurosemide administration prior to unenhanced CT is associated with decreased visualization of renal medullary hyperattenuation.© RSNA, 2010
