摘　　要：目的讨论经直肠彩色多普勒超声(TRUS)诊断前列腺癌的临床价值,通过对前列腺癌结节大小、位置、形态及血流特点,评价前列腺癌的超声诊断特点。方法应用经直肠彩色多普勒超声对30例已确诊前列腺癌患者进行检查,观察前列腺癌病灶大小、内部回声、包膜是否完整及血流特点。结果经直肠彩色多普勒超声可清晰显示前列腺结构及前列腺癌的特点,而且可以检测到前列腺癌内部血流信号,阻力指数。结论结合临床指诊及实验室PSA检查,可对前列腺癌做出初步诊断,提高前列腺癌的诊断率。Objective to discuss clinical value of transrectal color Doppler ultrasonography(TRUS)in diagnosis of prostate cancer,and evaluate ultrasonographic characteristics of prostate cancer based on analysis of size,location,shape and blood flow characteristics of prostate cancer nodules.Methods examine 30 cases prostate cancer patients with transrectal color Doppler ultrasonography.Observe size,internal echo,capsule integrity and blood flow characteristics of prostate cancer.Results transrectal color Doppler ultrasound can show structure of prostate and characteristics of prostate cancer clearly,and detect blood flow signal and resistance index in prostate cancer.Conclusion combined with clinical indexes and laboratory PSA examination,primary diagnosis can be made for prostate cancer,to improve diagnostic rate of prostate cancer.
