经直肠彩色多普勒超声诊断前列腺癌的价值

目的 探讨经直肠彩色多普勒超声诊断前列腺癌的价值。方法 应用经腹壁超声及经直肠彩色多普勒超声对17例前列腺癌患者的前列腺进行对比观察。结果 经直肠超声较经腹壁超声对前列腺癌的诊断更具敏感性，二者对该病的检出具有显著性差异(P＜0．05)。应用能量图方法可以更清晰显示前列腺内异常病变区血流且阻力指数明显增高。结论 经直肠彩色多普勒超声检查可以早期提示前列腺癌，利于患者的早期治疗及预后，对前列腺癌的诊断具有重要价值。

The Value of Transrectal Color Doppler Ultrasound Used for Diagnosing Prostate Carcinoma

Objective To evaluate color Doppler ultrasound used for diagnosing carcinoma of prostate. Methods 17 patients of prostate carcinoma were observed by transrectal ultrasound and transabdominal ultrasound in comparison. Results Transrectal ultrasound was more sensitive to prostate carcinoma than transabdominal ultrasound.There was significant difference of diagnosis rate between them( P <0 05).With color Doppler energy,blood flow in abnormal area of prostate became clear and resistant index rose obviously. Conclusions Transrectal color Doppler ultrasound can indicate prostate carcinoma in the early period,which may do good to early treatment and have a therapeutic result.It has high value for diagnosing prostate carcinoma.
