【摘要】 目的探讨经直肠超声引导前列腺穿刺活检的临床应用价值。方法 2011年1月至2012年1月,我科60例选患者在无麻醉情况下,采用经直肠超声引导10点前列腺穿刺活检,取出前列腺组织送病理检查。结果 60例患者中,前列腺癌检出率为53.3%。前列腺特异性抗原(PSA)水平的不同,前列腺结节超声显示率差异具有统计学意义(P=0.0246),前列腺结节显示率随PSA水平的增加而增加(P=0.0014);不同PSA水平组的病理结果差异具有统计学意义(P<0.0001),穿刺阳性率随PSA水平升高而逐渐上升。结论超声结节检出率会随着PSA水平升高而增大,前列腺癌的检出率均与PSA水平呈正相关。经直肠引导前列腺穿刺法阳性率较高,安全性好,具有很高的临床推广价值。更多还原

【Abstract】 Objective To evaluate the clinical value of transrectal ultrasound-guided prostate biopsy.Methods Sixty patients underwent 10 core prostate biopsy guided by transrectal ultrasound(TRUS) from January 2011 to January 2012.Results In 60 patients,the detection rate of prostate cancer were 53.3%(32/60).The display rates of prostate nodule by TRUS increased with the rising of prostate-specific antigen(PSA) levels(Z=-2.9971,P=0.0014).There was significantly different in display rates of prostate nodule of different PSA levels(χ2=9.3854,P=0.0246);The positive rates of biopsy increased gradually with the rising of PSA levels(Z=-4.3657,P<0.0001).There was significantly different in the pathological results of different groups(χ2=42.1727,P<0.0001).Conclusion The display of prostate nodule by TRUS increases with the rising of PSA levels.The detection rates of prostate cancer are positively correlated with PSA levels.The transrectal ultrasound-guided prostate biopsy has many advantages,such as more safety and less side effects,which will be valuable to the clinic.更多还原
