1、经冇•肠腔内彩色多普勒超声检杳对前列腺疾病诊断的临床价值【关键词】经直肠超声;,彩色多普勒;,前列腺;,PSA[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:対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,同吋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。结杲: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
2、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特界性更高(P<0.05),差界有显著性意义。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--,结合血流特征和PSA检测可提高对前列腺癌的诊断率。[关键词]经直肠超声;彩色多普勒;前列腺;PSAClinicalvalueoftransrectalcolordopplerultrasoundforprostaticdiseaseZHAOFeng,XINGHu,XUEYu,LIUMi

8、显示较人的前列腺肿块,对细微病变难以显示,限制了对早期前列腺癌的诊断,而前列腺特异抗原(PSA)虽己被广泛用于前列腺癌的筛选、诊断、随访,但PSA对前列腺癌组织并无特异性[1]。经直肠超声图像清晰,结合彩色多普勒血流参数,人大提高了对前列腺肿块的检出率,为临床提供了更准确的诊断信息。1对象与方法1.1病例2004年4月至2006年3月经直肠指诊
