摘要
目的:探讨延时尿路CT平扫对儿童IVU不显影病变的诊断价值。方法:2012年6月-2013年5月因泌尿系统病变行IVU检查的单侧或双侧肾脏不显影的31例患儿,行延时120min尿路CT平扫检查,检查结果与手术结果对照。结果:发现肾脏不显影的患儿31例(36侧),肾实质病变16.7%,肾盂病变19.4%,输尿管病变30.6%,反流病变33.3%,IVU/CT结果均与手术病理相符合。延时尿路CT平扫显示肾实质厚度无明显变化2.8%,肾实质变薄66.7%,肾实质菲薄30.6%;肾实质可见较明显强化16.7%,可见强化58.3%,未见明显强化25.0%。结论:延时尿路CT平扫对儿童IVU不显影病变临床诊断及肾功能评估提供依据。
Objective：To evaluate the value of delayed CT scanning in the diagnosis of disease in children with nondisplayed kidney on IVU.Methods：From June 2012 to May 2013,31 pediatric patients with unilateral or bilateral kidneys not displayed on IVU underwent delayed CT scanning 120 minutes after contrast injection for IVU.The diagnostic accuracy of IVU/CT was compared with the results of surgery.Results：Totally,36 kidneys didn＇t display on IVU in these 31 patients,there were renal parenchymal diseases in 16.7%,renal pelvic lesions in 19.4%,ureteral lesions in 30.6%,urine reflux in 33.3%.IVU/CT results were accorded with surgery and pathology findings.The delayed CT images displayed normal renal parenchymal thickness in 2.8%,thinning of renal parenchyma in 66.7%,marked thinning of renal parenchyma in30.6%.Renal parenchyma showed significant enhancement in 16.7%,mild enhancement in 58.3%,non-enhancement in 25.0%.Conclusion：Delayed CT scanning after IVU with non-displayed renal lesion on IVU might provide important reference for clinical diagnosis and renal function evaluation.
