摘　　要：目的　探讨经直肠彩色多普勒超声对前列腺移行带增生结节和癌结节的诊断价值。方法　经直肠彩色多普勒超声对 37例增生结节和 1 4例癌结节的形态、内部回声、边缘情况进行对比观察 ,并测量动脉收缩期最大血流速度 (Vs)、阻力指数 (RI)、搏动指数 (PI)。并进行统计学处理。结果　前列腺增生结节表现为形态规则、边界清晰、血流对称分布。癌结节表现为形态不规则、边界毛糙、血流丰富且非对称性分布。各项血流主要参数 (Vs、RI、PI)癌结节相对增生结节明显增大 (P<0 .0 5 )。结论　前列腺移行带癌结节比增生结节血流灌注增加、速度增快、阻力增高。Objective To investigate the sonographic appearance and hemodynamic features of hyperplastic nodules and prostatic cancer nodules in the prostatic transitional zone via color Doppler ultrasonography and to evaluate their clinical significance. Methods A total of 37 cases with prostatic hyperplasia and 14 cases with prostatic cancer were detected to observe their sonographic appearance and to measure the systolic peak volocity(Vs),resistance index(RI) and pulsatility index(PI). Results The sonographic appearance of hyperplastic nodules revealed the shapes more regular and edge more clear than prostatic cancer nodules,The blood flow signals in prostatic cancer nodules were increased and multiple while in hyperplastic nodule the flow was not.There was statistically significant differences in the parameters of flow signals between prostatic cancer nodules and hyperplastic nodules( P <0 05). Conclusions Transrectal color Doppler ultrasonography has important value in distinguishing hyperplastic nodules and prostatic cancer nodules in transitional zone.
