目的探讨原发性输尿管癌的超声声像图特点并分析其误诊原因。方法回顾21例经超声检查可疑原发性输尿管癌的超声声像图特点,与术后病理对比分析。结果 21例中,18例为输尿管癌,3例误诊;其中,输尿管节段实变型14例,团块型5例,输尿管全程浸润型1例,单纯输尿管狭窄1例。结论超声对原发性输尿管癌具有一定的诊断价值,但有些病例的声像图与其具有共性特点而易误诊,应予注意鉴别及改进扫查方法。
Objective To investigate the characteristics of ultrasonography of primary ureteral carcinoma and analyze its causes of misdiagnosis. Methods The echographic features of 21 cases with suspected primary ureteral carcinoma underwent ultrasonography were retrospectively analyzed and compared with postoperative pathology. Results Among 21 cases, 18 cases were ureteral carcinoma and 3 cases were misdiagnosed. Among them, 14 cases of ureteral segment consolidation, 5 cases of lumps, 1 case of ureteral full infiltration and 1 case of simple ureteral stricture. Conclusion Ultrasound has some diagnostic value for primary ureteral carcinoma, but some cases have common features and misdiagnosis, and should pay attention to identify and improve the scanning method.
