摘要
目的经直肠超声实时弹性成像引导前列腺穿刺活检的临床价值。方法对100例年龄47～85岁疑前列腺癌而行超声检查未发现有结节的患者，随机分为两组，年龄上无明显差异，A组使用经直肠超声实时弹性成像引导穿刺活检，B组运用经直肠常规彩超引导穿刺活检，术后送病理检查，以手术后病理结果为金标准，比较两组的阳性率。结果所取标本均病理制片成功。所有患者手术后病理结果为前列腺癌的有60例，A组检出34例（68％），B组检出23例（46％），两者差异有统计学意义（P〈0．05）。结论经直肠超声实时弹性成像引导前列腺穿刺活检，特别是在常规超声检查未发现结节的患者，可根据不同区域弹性值的大小，选择硬度较大的区域进行有针对性的穿刺，可提高穿刺活检的阳性率。
Objective To explore the clinical value of prostate biopsy guided by transrectal ultrasound real - time elastography. Methods One hundred patients who were suspected prostate cancer but found no nodules by ultrasound examination, were included in the study. A and B group were performed with transrectal ultrasound real - time elastography and conventional transrectal ultrasound guided prostate biopsy Respectively. The specimens were sent to do pathological examination. The surgery pathology results as the gold standard. The detection rate of the two groups were compared. Results All the pathological specimens were taken successful. Fanally,60 patients were diagnosed with prostate cancer. Thirty- four（68% ） patients detected by A group and twenty five （50%） patients detected by B group, transrectal ultrasound real - time elastography was significantly accurate compared with conventional transrectal ultrasound （ P 〈 0.05 ）. Conclusion Prostate biopsy guided by real - time elastography transrectal ultrasound can improve the positive biopsy rate of pa- tients. Especially the patients who were not found nodules by routine ultrasound examination can according the size of the different areas of elasticity values to select a larger area hardness targeted puncture.
