目的 :探讨肾盂癌的二维及彩色多普勒超声检查方法 ,以进一步提高肾盂癌超声诊断准确率。方法 :肾盂肿瘤患者 4 0例 ,超声发现肾盂内肿块后观察其位置、形态、大小、内部回声及肿瘤内部和周边的彩色血流情况。结果 :二维超声及 CDFI检查准确率占 75 % ,2例误诊为肾癌 ,4例误诊为肾囊肿 ,4例漏诊。结论 :肾盂肿瘤较少见 ,因肿瘤过大或过小易造成漏、误诊。超声对肾盂肿瘤检查有很大帮助
Objective: To investigate the two-dimensional and color Doppler ultrasonography of renal pelvic cancer to further improve the diagnostic accuracy of renal pelvic cancer. Methods: Forty patients with renal pelvis and tumor were examined by sonography. The location, shape, size, internal echo and the color flow in and around the tumor were observed. Results: The accuracy of two-dimensional ultrasound and CDFI was 75%. Two cases were misdiagnosed as renal cell carcinoma, four cases were misdiagnosed as renal cysts and four cases were missed. Conclusion: The renal pelvis tumors are rare, due to tumor is too large or too small can easily lead to misdiagnosis. Ultrasound of renal pelvic tumor examination is very helpful
