目的探讨腹部X线、超声与CT检查在肾错构瘤中的诊断价值。方法选取自贡市第一人民医院2012年7月—2016年1月收治的肾错构瘤患者40例,患者均行腹部超声、X线与CT检查。比较不同影像学检查结果,并分析不同影像学检查的图像特征。结果 CT检查灵敏度、特异度、符合率、Youden指数高于超声、X线检查,超声检查灵敏度、特异度、符合率、Youden指数高于X线检查(P<0.05)。CT检查在诊断肿块边界是否清楚、形态是否规整、有无包膜的符合率高于超声、X线检查,超声检查在诊断肿块边界是否清楚、形态是否规整的符合率高于X线检查(P<0.05)。3种影像学检查诊断肾盂内阳性结石的符合率均为100.00%。结论腹部CT、超声检查均适用于肾错构瘤诊断,诊断价值高。
Objective To investigate the diagnostic value of abdominal X-ray, ultrasonography and CT in renal hamartoma. Methods Forty patients with renal hamartoma who were admitted to the First People’s Hospital of Zigong City from July 2012 to January 2016 were examined by abdominal ultrasonography, X-ray and CT. Compare different imaging findings and analyze image features of different imaging studies. Results The sensitivity, specificity, coincidence rate and Youden index of CT examination were higher than those of ultrasound, X-ray examination, ultrasonic examination sensitivity, specificity and coincidence rate. The Youden index was higher than X-ray examination (P <0.05). CT examination in the diagnosis of mass border is clear, the shape is regular, with or without capsule in line with the rate higher than ultrasound, X-ray examination, ultrasound examination in the diagnosis of mass border is clear, the shape of the regularity of compliance rate is higher than the X-ray examination (P <0.05). The coincidence rates of three kinds of imaging diagnosis of positive renal pelvis were 100.00%. Conclusion Abdominal CT and ultrasonography are both suitable for the diagnosis of renal hamartoma, with high diagnostic value.
