高频与低频超声联合检查对原发性输尿管癌的诊断价值

The value of low frequency ultrasonography combined with high frequency ultrasonography in diagnosis of primary ureteral carcinoma

目的探讨高频与低频超声联合检查对原发性输尿管癌的诊断价值。方法回顾性分析我院11例经手术和病理证实的原发性输尿管癌患者的超声图像表现特点。所有患者均先行低频探头检查,了解输尿管的梗阻平面、扩张程度、输尿管内有无肿块;发现病灶后再行高频扫查,观察肿块的超声特征、输尿管管壁情况以及是否合并周围浸润或转移。结果 11例患者中,低频探头扫查检出输尿管内病灶7例,病变内部回声特征和血供情况显示不满意,联合高频超声检查,检出病灶10例,高频探头扫查时病灶及病灶内部血流显示率均较高,且病灶与周围组织关系显示更清晰。结论高频与低频超声联合扫查输尿管能提高对原发性输尿管癌的诊断准确率。

Objective To investigate the value of low frequency ultrasonography combined with high frequency ultrasonogra- phy in diagnosis of primary ureteral carcinoma. Methods The ultrasonic images of 11 patients with pathologically confirmed primary ureteral carcinoma were retrospectively analyzed. These patients were scanned with low frequency probe firstly. We made clear the plane of ureteral obstruction and the degree of dilation of ureter and there was a lump in the ureter or not. And then high frequency ultrasonography was combined with after the lesion was found. We observed the ultrasonic features of the masses, the condition of the ureteral wall and the surrounding invasion or metastasis Results Of the 11 patients, 7 patients were diagnosed by low frequency ultrasonodraphy. The detection rate of the internal ultrasonic characteristics and blood supply of the lesions were not satisfactory. 10 patients were diagnosed by high frequency combined with low frequency ultrasonography. The detected rate of high frequency ultra- sonography was high in detecting lesions and blood flow signal in the lesions. The relationship between the lesion and surrounding tissue showed more clearly. Conclusion High frequency combined with low frequency ultrasonography for the ureter can raise the di- agnosis accuracy rate of primary ureteral carcinoma.
