目的:分析肾脏恶性肿瘤经超声显像诊断的价值,为提高该病的诊断水平和临床治疗提供科学依据。方法:从我院2010年9月-2014年9月确诊的肾脏恶性肿瘤患者中随机抽取80例进行研究,对其术前超声诊断资料进行回顾性分析,并和术后病理活检结果进行对比分析,总结误诊和漏诊的影响因素。结果:(1)经比较,术前超声诊断定性诊断的准确率为90.00%,误诊率和漏诊率分别为2.50%和7.50%;定位诊断的准确率为96.25%,误诊率和漏诊率分别为0.00%和3.75%;和术后病理诊断100%比较,不存在明显差异,没有统计学意义(P>0.05)。(2)经超声定性诊断,共有53例为肾细胞癌,8例为肾盂癌,5例为肾母细胞瘤,3例转移癌,剩余11例分别为分隔肾性占位、肾结核、肾柱肥大、肾囊肿板囊壁钙化、肾积水伴凝血块,其诊断符合率分别为89.83%、72.73%、71.43%和100.00%,其余则均为0.00%。结论:肾脏恶性肿瘤患者经超声显像具有较高的诊断价值,诊断准确率高,能动态反应恶性肿瘤的内部结构和形态的变化及特点,可以为该病的临床治疗提供重要的参考价值。同时,注意甄别极少数的特殊表现,减少误诊和漏诊,提高诊断准确率。
Objective: To analyze the value of ultrasound in the diagnosis of renal malignant tumors and provide a scientific basis for improving the diagnosis and clinical treatment of this disease. Methods: Totally 80 cases of renal malignancy were diagnosed from September 2010 to September 2014 in our hospital. The data of preoperative ultrasound diagnosis were retrospectively analyzed and compared with postoperative pathological biopsy results , Summarizes the factors of misdiagnosis and missed diagnosis. Results: (1) The accuracy rate of preoperative ultrasound diagnosis was 90.00%, the misdiagnosis rate and misdiagnosis rate were 2.50% and 7.50%, respectively. The accuracy rate of positioning diagnosis was 96.25%, the misdiagnosis rate and misdiagnosis rate were 0.00% and 3.75% respectively. There was no significant difference between the two groups (P> 0.05). (2) According to the qualitative diagnosis by ultrasound, there were 53 cases of renal cell carcinoma, 8 cases of renal pelvic cancer, 5 cases of nephroblastoma and 3 cases of metastatic carcinoma. The remaining 11 cases were divided into renal territory, renal tuberculosis and kidney Column hypertrophy, renal cyst wall calcification, hydronephrosis with coagulation, the diagnostic coincidence rates were 89.83%, 72.73%, 71.43% and 100.00%, respectively, the rest were 0.00%. Conclusion: Ultrasound imaging of renal malignant tumor patients has high diagnostic value, high diagnostic accuracy, can dynamically respond to changes in the internal structure and morphology of malignant tumors and features that provide an important reference value for the clinical treatment of the disease. At the same time, pay attention to screening a very small number of special performance, reduce misdiagnosis and missed diagnosis, improve diagnostic accuracy.
