摘　　要：目的评价经直肠超声(TRUS)结合彩色多谱勒血流图象(CDI)对前列腺穿刺活检的指导作用.方法依据TRUS结合CDI选择穿刺点,采用个体化方案对192例PSA＞4ng/m1、可疑前列腺癌(PCA)的患者,行经直肠前列腺穿刺活检,对其中12例PSA持续升高者行重复穿刺.结果 (1)PSA4～10ng/m170例,PCa9例(12.9%)、其中7例CDI有异常血流;阴性61例、其中9例CDI有异常血流.(2)PSA11～150ng/m1122例,PCa47例(38.5%)、其中37例CDI有异常血流;阴性75例、其中14例CDI有异常血流.CDI在PCa与穿刺阴性间比较有极显著性差异(P＜0.001),重复穿刺者12例中发现PCA5例.结论依据TRUS结合CDI采用个体化方案的前列腺穿刺活检术,能提高PCa检出率和减少并发症.Objective To evaluate the guiding effect of transrectal ultrasound (TRUS) combined with colordoppler image (CDI) on prostate biopsy. Methods Those who were suspected to suffer from PCA with their PSA areall higher than normal were examined, and the biopsy cores were chosen according to the transrectal ultrasound andcolor doppler image. Among those patients, 12 cases have a constantly high PSA have to take a second biopsy. ResultsPatients were divided into 2 groups. (A) In this group, there were 70 cases, their PSA were between 4 to 10ng/ml, and9 (12.9%) of them had PCa, while 7 of them had abnormal blood flow. On the other hand, the number of abnormal bloodflow in those who had a negative result (n=61) was 9. (B) In this group, 122 cases’ PSA were 11-150ng/ml. Positive PCaresult was found in 47(38.5%) cases, 37 of them had abnormal blood flow, while the number of abnormal blood flow innegative result (n=75) was 14. CDI has significant difference between positive and negative PCa (P<0.001). 5 cases ofPCa were found in those who received a second biopsy. Conclusion According to the transrectal ultrasound combinedwith color doppler image (CDI) guided prostate biopsy would enhance significantly the cancer detection rate and reducethe complication.
