目的：评价经直肠彩色超声多元素鉴别诊断前列腺增生与前列腺癌的应用价值。方法选取2011年2月至2013年5月期间收治的良性前列腺增生患者130例及前列腺癌患者30例作为研究对象，另选30例健康人作为对照组。三组研究对象均经超声引导穿刺后组织病理活检或是手术后组织活检确诊。采用多普勒超声诊断仪对三组各径线，以及前列腺病灶内部或周边动脉收缩期最大血流速度（Vs）、阻力指数（RI）及搏动指数（PI）进行观察。结果前列腺增生组与前列腺癌组患者前列腺平均体积大小相当，两组之间比较无统计学差异（ P ﹥0.05），两组患者前列腺体积与对照组相比显著增大，差异具有统计学意义（ P ﹤0.05）；与前列腺癌组和对照组相比较，前列腺增生组患者前后径、左右径增大较多，上下径增大偏小；与对照相组较，前列腺癌组患者上下径增大较多，前后径、左右径增大偏小。前列腺癌组 Vs、RI、PI 值明显高于前列腺增生组，差异具有统计学意义（ P ﹤0.05）。结论经直肠彩色多普勒超声探查在鉴别诊断前列腺增生与前列腺癌上是比较理想的一种检查手段。

Objective To evaluate by transrectal color ultrasonic multielement differential diagnosis of prostatic hyperplasia and prostate cancer. Methods From February 2011 to May 2013 in our hospital during the period,130 patients with benign prostatic hyperplasia and prostate cancer patients 30 cases were included as the research object. At the same time,we choosed 30 cases of healthy people as control group. The diag-nosis was established by ultrasound - guided puncture biopsy tissue pathology biopsy or surgical confirmation. Each diameter line detected by Doppler ultrasound,and prostate lesions internal or peripheral artery peak systolic velocity(Vs),resistance index(RI)and pulsatility index(PI) were observed. Results Patients with prostatic hyperplasia and prostate cancer group did not show statistical difference between two groups in the average volume size of prostate( P ﹥ 0. 05). The prostate volume in two groups of patients increase significantly compared with control group. The difference has statistical significance( P ﹤ 0. 05). Compared with the control group of prostate cancer,prostatic hyperplasia patients before and after about diameter,diameter is more,from top to bottom diameter smaller. With the photographic group,the group of patients with prostate canc-er and diameter,diameter,small diameter around. Prostate cancer patients can appear local jacksonian FengFuOu blood flow,its surrounding can form arc signal. The blood flow signal in prostate hyperplasia patients was less,form bow signal does not appear. Compared between two groups of the blood flow signal,statistically significant difference was found( P ﹤ 0. 05). Conclusion Transrectal color doppler ultrasound in the differen-tial diagnosis of prostate hyperplasia and prostate cancer is one of the ideal inspection method.
