二维超声及彩色多普勒血流显像评价肾盂移行细胞癌

本文应用二维超声及彩色多普勒血流显像（CDFI）检查肾盂移行细胞癌26例。结果显示：81％的病例具有典型的声像图，即患例肾窦回声分离，内有一弧立的实性肿瘤回声，以低回声表现居多。体积大且侵犯肾实质的肿瘤易误诊，而体积较小的肿瘤易漏诊。CDFI示86％（6／7）的肿瘤内部无血流信号。二维超声结合CDFI的诊断准确性为84.6％。作者分析了肾盂癌的超声诊断和鉴别诊断，认为二二维超声和CDFI联合应用对本病的诊断有很大帮助。

Two Dimensional Ultrasonography and Color Doppler Flow Imaging for Evaluating Renal Pelvic Transitional Cell Carcinoma

Two diamensional ultrasonography and color Deppler flow imaging were utilized to assess 26 patients with renal pelvic transitional cell carcinoma. Twenty-one (81 % ) tumors had ultrasonographic characters as discrete, solid masses causing separation of the central renal sinus echoes. Many neoplasms were hypoechoic. CDFI showed absence of visible vascularity in 6 of 7 tumors. The accurate diagnostic rate of the 2DUS with CDFI was 84. 6%.
