摘要
目的评估经直肠彩超引导下前列腺穿刺活检术在前列腺癌诊断和鉴别诊断中的价值。方法对直肠指检阳性或经直肠彩超检查怀疑有占位性病变的35例患者行经直肠彩超引导下前列腺穿刺活检。结果经直肠彩超引导下穿刺诊断前列腺癌的敏感度、特异度分别为84.2%、81.5%,与手术切检比较差异无统计学意义;前列腺癌病灶RI≥0.75者所占比例显著高于非前列腺癌结节者(P<0.05)。结论经直肠彩超引导下前列腺穿刺活检操作简单、安全,对前列腺癌的诊断具有重要的指导意义。
Objective To evaluate the value of transrectal ultrasound （TRUS）-guided biopsy for differential diagnosing prostate cancer （PCa） from other prostatic diseases. Methods Transrectal ultrasound-guided biopsy was performed on 35 patients whose digital rectal examination showed positive results, and TRUS results showed suspected abnormalities. Results The diag- nostic sensitivity of TRUS-guided biopsy was 84. 2%, and its specificity was 81.5%. Conclusion Biopsy guided by TRUS is convenient and safe, and has important significance for clinical diagnosis.
