目的评价二维灰阶(2D)及彩色多普勒超声(CDFI)对肾细胞癌的诊断价值。方法对66例经手术病理证实为肾细胞癌的超声表现及超声定性诊断进行回顾性分析,以术后病理为对照,得出超声对肾细胞癌病灶的检出率及定性诊断符合率。结果66例肾细胞癌中,超声正确诊断59例,误诊4例,漏诊1例,未能定性诊断2例,超声对病灶的检出率为98.5%(65/66),定性诊断符合率为89.4%(59/66)。结论超声对肾细胞癌的诊断有很高的临床应用价值,尤其超声体检普查对于肾癌的早期发现具有重要意义,可作为大量健康人群进行肾癌普查以及肾细胞癌患者术前诊断的首选检查方法。
Objective To evaluate the diagnostic value of two-dimensional gray scale (2D) and color Doppler ultrasound (CDFI) in renal cell carcinoma. Methods Sixty-six cases of renal cell carcinoma confirmed by surgery and pathology were retrospectively analyzed by ultrasound and ultrasound. According to the postoperative pathology, the detection rate and the coincidence rate of qualitative diagnosis of renal cell carcinoma by ultrasound were obtained. Results In 66 cases of renal cell carcinoma, 59 cases were correctly diagnosed by ultrasound, 4 cases were misdiagnosed, 1 case was misdiagnosed, 2 cases were not diagnosed qualitatively, and the detection rate of lesions by ultrasound was 98.5% (65/66). The coincidence rate of qualitative diagnosis was 89.4% (59/66). Conclusion Ultrasound has a high clinical value in the diagnosis of renal cell carcinoma. In particular, the ultrasound examination for the early detection of renal cell carcinoma is of great significance, as a large number of healthy people screening for renal cell carcinoma and renal cell carcinoma preoperative diagnosis of patients preferred examination method.
