原发性输尿管肿瘤的超声诊断价值

Ultrasonographic Diagnosis of Primary Ureteral Tumor

目的:探讨原发性输尿管肿瘤的声像图特点。方法:回顾性分析经手术和病理证实的11例原发性输尿管肿瘤,对其大小、位置、声像图特点、肾积水程度及临床症状进行研究。结果:11例病灶中检出6例,位于输尿管上段1例,位于下段或末端5例,显示为高回声团块4例,显示为低回声团块2例,误诊为膀胱占位2例,因腹腔胀气严重,无法探及病灶的3例,11例均有肾积水。结论:原发性输尿管肿瘤声像图表现具有一定的特征,超声检查再结合其临床特点对其诊断与鉴别诊断具有重要价值。

Objective： To discuss the sonographic features of primary ureteral tumor. Methods A retrospective review was performed in 11 patients with pathologically confirmation. Tumor size, location, and sonographic features were evaluated. Results Six of the eleven cases were diagnosed successfully, one was on the upside of the ureter, the other five were on the bottom, among them, four cases had the mass with hyperechoic, two had the mass with hypoechoic. Two cases were diagnosed as the tumor of bladder by mis- take. And the other three cases can not be diagnosed because of the intestinal tympanites. All of them had the hydronephrosis. Conclusion The characteristic of ultrasonography combined with clinical feature will be of great value in diagnosis and differential diagnosis of primary ureteral tumor.
