目的比较各种前列腺系统穿刺活检方案在不同前列腺体积及血清前列腺特异性抗原水平的临床价值。方法对153例有前列腺穿刺活检指征的患者行经直肠彩超引导下前列腺15针系统穿刺活检术,通过选择不同穿刺部位及针数,形成6、8、10、12、15针法,并进行回顾性分析。结果本组共检出前列腺癌59例,其中6、8、10和12针法检出阳性率分别为72.9%(43/59)、83.1%(49/59)、88.1%(52/59)和98.3%(58/59);血清总前列腺特异性抗原>100μg/L的前列腺癌患者15例,6针法即可检出全部15例而无漏诊;前列腺体积≤40mL组8针法检出率100%(22/22),前列腺体积>40mL组12针法检出率97.4%(37/38)。结论 12针法检出率优于≤10针的前列腺穿刺活检方案。
Objective To compare the clinical value of various prostatic biopsy protocols in different prostate volumes and serum prostate-specific antigen levels. Methods 153 patients with prostatic biopsy indications underwent transrectal ultrasound-guided prostatic 15-needle biopsy, by selecting a different puncture site and the number of needles, the formation of 6,8,10,12,15-pin method and review Sexual analysis. Results 59 cases of prostate cancer were detected in this group, of which the positive rates of 6, 8, 10 and 12 were 72.9% (43/59), 83.1% (49/59) and 88.1% (52/59) And 98.3% (58/59) respectively. Serum total prostate specific antigen> 100μg / L in 15 cases of prostate cancer patients, all 6 cases were detected without any missed diagnosis; prostate volume ≤ 40ml group was detected by 8-pin method Rate of 100% (22/22), prostate volume> 40mL group 12 needle method detection rate of 97.4% (37/38). Conclusion The detection rate of 12-gauge needle is better than that of prostate needle biopsy with ≤ 10 needle.
