输尿管癌的超声诊断价值

Diagnostic value of ultrasonography in ureteral cancer

目的探讨超声检查在输尿管癌诊断中的价值。方法分析34例输尿管癌患者声像图特点,并与手术结果对照。结果超声发现肾盂输尿管积水33例,单纯患侧肾盂积水1例;输尿管癌19例,肿瘤以较低回声为主,沿输尿管长轴方向生长;肿瘤长径平均25.3mm,输尿管扩张的直径平均11mm。位于输尿管下端的肿瘤可向膀胱内突出,表现为等回声;肿瘤内均探及条点状血流信号。超声误诊5例,漏诊10例。结论超声检查是输尿管癌的首选筛查方法,对临床高度怀疑输尿管癌的患者,超声检查要全面、多途径相结合。

Objective To analyze the diagnostic value of ultrasonography in ureteral cancer. Methods Thirty - four patients with ureteral cancer confirmed by surgery and histopathology were selected as the objects of this study, sign and results of ultrasonography were analyzed retrospectively. Results The sonography showed 33 patients with nephredema and hydroureter, 1 patient with nephredema. The sonography detected 19 patients with ureteral cancer. The tumour located in the ureter showed a homogeneous low echo. The tumour was distributed along the ureteral axis. Average length of the ureteral tumour was 25.3mm, average diagnosis of hydroureter was 11 mm. The tumour which located at the end of the ureter and extruded to the bladder showed iso - echoic. The blood flow was detected in all the tumours by CDFI. Five cases were misdiagnosed, and 10 cases were missed diagnosed. Conclusion ultrasonography is the first screening method for ureteral cancer. The sonography should be careful and overall to the patients with suspected ureteral cancer.
