目的:探讨超声造影对输尿管肿瘤诊断的临床应用价值。方法:回顾性分析25例输尿管肿瘤常规超声及超声造影的声像图表现及诊断结果,评估超声造影的诊断准确性。结果:术后2例诊断为输尿管良性肿瘤,23例诊断为输尿管尿路上皮癌,常规超声和超声造影的诊断准确率分别为68%(17/25)和92%(23/25)。结论:超声造影作为一种新技术,在输尿管肿瘤诊断方面具有良好的应用前景,可提高输尿管肿瘤的临床诊断准确率。
Objective: To investigate the clinical value of contrast-enhanced ultrasound in the diagnosis of ureteral tumors. Methods: A retrospective analysis of 25 cases of ureteral tumors by conventional ultrasound and contrast-enhanced ultrasound imaging and diagnostic results to assess the diagnostic accuracy of contrast-enhanced ultrasound. Results: Two cases were diagnosed as benign ureteral tumors and 23 cases were diagnosed as ureteral urothelial carcinomas. The diagnostic accuracy of routine ultrasound and contrast-enhanced ultrasound were 68% (17/25) and 92% (23/25) respectively. Conclusion: As a new technique, CEUS has good application prospect in the diagnosis of ureteral tumors and can improve the diagnostic accuracy of ureteral tumors.
