[摘 要]目的: 探讨经直肠腔内彩色多普勒超声检查前列腺疾病的临床价值。方法: 对80例54～91岁男性经直肠指检(DRE)检出前列腺增大患者应用经腹壁及经直肠腔内超声(TRUS)检查，同时进行前列腺特异抗原(PSA)检 测分析，并全部经尿道电气化切除(TUVP)或经腹手术病理证实。结果: 前列腺癌19例，单纯前列腺增生以及伴有炎症、钙化、囊肿等共61例。经直肠超声检查前列腺癌的准确度为84%，而经腹超声检查与PSA检测前列腺癌的准确度分别为71%与68%，经直肠超声比经腹超声敏感性更高(P<0.01)，比PSA特异性更高(P <0.05)，差异有显著性意义。结论: 经直肠检查前列腺，图像清晰，测量准确，分辨力佳，是诊断前列腺疾患的最佳途径和方法之一，结合血流特征和PSA检测可提高对前列腺癌的诊断率。

    [Abstract] Objective: To evaluate the clinical value of transrectal color Doppler ultrasound in diagno- sing prostate disease. Methods: A total of 80 patients with prostatic hypertrophy due to digital rectal exami- nation(DRE) underwent abdominal ultrasound and transrectal ultrasound(TRUS) examination，the results were compared with the pathology and PSA . Results: Among 80 patients 19 cases of prostatic cancer(PC)were confirmed by transurethral electrovaporization of the prostate(TUVP) and pathology ......
