目的:探讨影像学检查在小肾癌诊断中的应用价值。方法:回顾性分析我科35例术后经病理确诊为小肾癌患者的B超、IVU、CT、MRI等影像学资料,比较分析各影像学检查的优缺点。结果:35例小肾癌病例,常规行B超、IVU检查,并结合CT或MRI检查。其中,B超诊断肾癌23例,准确率65.7%。IVU提示有肾盂肾盏受压等间接征象5例(14.3%)。21例行CT检查,诊断肾癌20例,准确率95.2%。14例行MRI检查,诊断肾癌13例,准确率92.9%。结论:综合应用B超、IVU、CT和MRI检查对于小肾癌的早期诊断具有重要意义,尤以CT检查更具价值。
Objective: To investigate the value of imaging in the diagnosis of small renal cell carcinoma. Methods: We retrospectively analyzed the imaging data of 35 cases of small renal cell carcinoma confirmed by pathology, such as B-ultrasound, IVU, CT, MRI and so on, and analyzed the advantages and disadvantages of each imaging examination. Results: 35 cases of small renal cell carcinoma, routine B-ultrasound, IVU examination, combined with CT or MRI examination. Among them, B-diagnosis of renal cell carcinoma in 23 cases, the accuracy rate of 65.7%. IVU prompt pyelonephrosis and other indirect signs in 5 cases (14.3%). 21 cases of CT examination, diagnosis of renal cell carcinoma in 20 cases, the accuracy rate of 95.2%. 14 cases of MRI examination, diagnosis of renal cell carcinoma in 13 cases, the accuracy rate of 92.9%. Conclusion: Comprehensive application of B-ultrasound, IVU, CT and MRI examination is of great significance for the early diagnosis of small renal cell carcinoma, especially CT examination is more valuable.
