目的 评价肾损伤的检查方法 ,探讨CT诊断和分类的临床价值。材料与方法 对 70例肾损伤CT表现作回顾性分析。结果 70例中左肾损伤 3 9例 ,右肾 3 0例 ,双肾 1例。CT表现为肾影增大 3 0例 ( 4 2 .9% ) ,肾轮廓不规则 15例 ( 2 1.4% ) ,肾包膜下血肿 43例 ( 61.4% ) ,肾内血肿 3 5例 ( 5 0 .0 % ) ,肾周积血 2 9例 ( 4 1.4% ) ,肾节段性梗塞 8例 ( 11.4% ) ,轻度肾实质挫伤 4例 ( 5 .7% ) ,肾撕裂或断裂 41例 ( 5 8.6% ) ,肾粉碎 5例 ( 7.1% ) ,肾动脉主干断裂或闭塞 2例 ( 2 .9% )。另外尚有肝、脾破裂等合并伤表现。结论 CT平扫加增强检查对肾损伤定性诊断准确率达 10 0 % ,分类诊断准确率达 92 .7% ,CT分类对临床选择治疗方案有重要指导价值。
Objective To evaluate the method of renal injury and to explore the clinical value of CT diagnosis and classification. Materials and Methods A retrospective analysis of CT findings of 70 cases of renal injury. Results 70 cases of left kidney injury in 39 cases, 30 cases of right kidney, kidney in 1 case. CT showed renal enlargement 30 cases (42.9%), kidney irregular 15 cases (2 1.4%), subencapsular hematoma in 43 cases (61.4%), intrarenal hematoma 35 cases (5 0%), 29 cases of renal hemorrhage (4 1.4%), 8 cases of renal segmental infarction (11.4%), mild renal contusion in 4 cases (5.7%), renal tearing or rupture There were 41 cases (5.66%), 5 cases (7.1%) with renal crushing and 2 cases (2.9%) with broken or occluded renal artery. In addition there are liver, spleen rupture and other manifestations of injury. Conclusions The accuracy of CT scan and contrast enhancement in the qualitative diagnosis of renal injury is 100%, and the diagnostic accuracy of classification is 92.7%. The classification of CT has important guiding value for the clinical treatment of choice.
