【摘要】目的：探讨前列腺癌（prostate cancer，PCa）经直肠超声声像图特征进一步提高 PCa 穿刺活检阳性率。

方法：前列腺特异性抗原升高和（或）直肠指诊阳性或经直肠超声发现前列腺可疑结节的159例患者，分成对照组与观察组，对照组（70例）行超声引导经直肠12点前列腺系统穿刺；对确诊为 PCa 患者的声像图总结分析。

观察组（89例）在对照组总结出的 PCa 声像图特征的基础上行经直肠超声引导系统6点加目的性穿刺。

结果：对照组中确诊为 Pca 22例，阳性率31.4%（22/70），观察组中确诊为 Pca 29例，阳性率32.6%（29/89），两组比较差异无统计学意义（ P >0.05）。

结论：前列腺形态失常或包膜不完整、外腺低回声结节、团块、血流异常丰富的结节及血流弥漫增多均提示 PCa，是穿刺活检的重点。

%Objective:To investigate ultrasonographic features of prostate carcinoma( PCa)with transrectal ultrasound guided biopsies and increase the positive rate of prostate biopsy. Nethods:159 cases of patients referred for high prostate specific antigen and/ or abnormal digital rectal examination or suspicious prostate nodules found by transrectal ultrasound were divided into control group and improvement group. The 70 cases in the control group were treated with transrectal ultrasound guided systematic 12 cores prostate biopsy and the ultrasonographic features of the patients confirmed with PCa were analyzed and
summarized. The 89 cases in the improvement group were given transrectal ultrasound guided systematic 6 cores plus purpose puncture on the basis of the ultrasonographic features summarized in the control group.Results:22 cases in the control group were diagnosed with PCa with the positive rate as 31. 4 % ,and 29 cases in the improvement group were confirmed as 32. 6 % . There was no significant difference between the two groups( P > 0. 05). Conclusions:PCa is highly doubted in the case of the following ultrasonographic features:prostate irregular shape or incomplete capsules,hypoechoic nodules in the outer gland,block mass,nodes with abnor-mal and abundant blood flow,which are the focus of the biopsy.【总页数】2页(P34-35)
