目的:探讨和分析传统二维及彩色多普勒超声在诊断肾细胞癌中的价值。方法:对我院2008-2011年收治的40例手术病理证实为肾细胞癌的肾脏肿瘤患者的二维和彩色多普勒超声的检查诊断结果进行回顾性分析,并与CT检查结果相比较。结果:对患者的超声和CT检查结果与术后病理诊断进行对比,超声诊断率82.5%,CT诊断率92.5%,两种检查诊断率相比无显著差异(x2=2.9,P>0.05)。其中,彩色多普勒超声表现为抱球型和丰富血流型的肾癌,术前均定性诊断正确(29/29)。对于星点型的肾脏肿瘤,诊断符合率较高(4/6)。对于少血流型肿瘤,超声无法作出正确的定性诊断(0/5)。结论:传统二维及彩色多普勒超声在诊断肾细胞癌中具有很高价值,可以作为早期筛查的检查方法,尤其是血供丰富的肾癌,其对小肾癌也有较高的诊断率。
Objective: To explore and analyze the value of traditional two-dimensional and color Doppler ultrasound in the diagnosis of renal cell carcinoma. Methods: The diagnostic results of two-dimensional and color Doppler ultrasonography in 40 patients with renal cell carcinoma confirmed by surgery and pathology in our hospital from 2008 to 2011 were retrospectively analyzed and compared with the results of CT examination. Results: The results of ultrasonography and CT examination were compared with postoperative pathological diagnosis. The diagnostic rate of ultrasound was 82.5% and the diagnostic rate of CT was 92.5%. There was no significant difference between the two methods (x2 = 2.9, P> 0.05). Among them, color Doppler ultrasound manifests as hemoglobin and rich blood flow type of renal cell carcinoma, which are correctly diagnosed preoperatively (29/29). For the star point of renal tumors, the diagnosis of high coincidence rate (4/6). For less blood type tumors, ultrasound can not make a correct qualitative diagnosis (0/5). CONCLUSION: Conventional two-dimensional and color Doppler ultrasonography is of great value in the diagnosis of renal cell carcinoma and can be used as an early screening test, especially in the blood-rich renal cell carcinoma, which has a higher diagnosis of small renal cell carcinoma rate.
