摘要
目的探讨体积大于50mL的前列腺阳性穿刺率与穿刺针数的关系并分析其原因。方法选择2006～2008年间于该院行超声引导下经直肠前列腺穿刺术的180例患者(其前列腺体积均大于50mL),按照穿刺针数分为6针组及12针组,计算并比较两组间的阳性穿刺率。结果6针组的阳性穿刺率为11.3%(9/80),12针组的阳性穿刺率为24%(24/100),两组间差异有统计学意义(P<0.05)。结论前列腺体积是影响穿刺率阳性的重要因素,当前列腺体积大于50mL时应增加穿刺针数,减少漏诊率。
Objective To investigate the relationship between core number and prostate cancer detection rate. Methods A total of 180 eases received transrectal ultrasound guided prostate biopsy for cancer detection at our hospital from 2005 to 2008. The total prostate volume of all cases were all larger than 50 millilitre. Patients were divided into two groups according the core numbers： 6 core group and 12 core group, and their cancer detection rate were compared. Results The cancer detection rate in the 6 core group was 11.3%, and 24% in the 12 core group. There existed significant differences between the two groups in cancer detection rate. Conclusion The prostate volume is an important factor in cancer detection rate. More core number is needed when the prostate volume is larger than 50.
