超声引导下经会阴穿刺活检在前列腺癌诊断中的价值

目的：探讨超声引导下经会阴道前列腺穿刺活检诊断前列腺癌的价值。方法：对376例临床怀疑前列腺癌患者行直肠腔内超声引导下经会阴前列腺穿刺活检。分3组。A组：184例，为指检前列腺触及结节或前列腺增大、质硬怀疑前列腺癌者；B组：84例，为因前列腺增生行直肠腔内超声检查发现有异常回声区域者；C组：108例，为指检未及明显硬节而血中PSA＞10ng/ml者。结果：3组穿刺活检阳性率分别为44．5％（82／184），29．8％（25／84），57．4％（62／108）。结论：直肠腔内超声引导下经会阴穿刺活检取材准确，能清楚显示穿刺针的径路和深度，避免损伤邻近脏器，可重复操作，明显提高穿刺活检的阳性率。

Ultrasound guided transperineal prostatic biopsy for the diagnosis of prostatic cancer

Objective To evaluate transperineal prostat ic biopsy guided by ultrasound for prastatic cancer. Methods 376 patients with clinical symptoms and signs suspecting prostatic cancer or other prostatic entities with abnormal ultrasonic findings and a higher level of serum PSA (>10 ng/ml) were studied by intrarectal transperineal prostatic bi opsy guided by ultrasound.The patients were divided into three groups.A group:18 4 cases with clinical symptoms and signs suspected of prostatic cancer.B group: 84 cases with BPH had an abnormal ultrasonic finding.C group:108 cases had a hig her level of serum PSA (>10 ng/ml). Results The diagnost ic rate of 3 groups was 44.5%,29.8%,57.4% respectivly. Conclusions The advantages of the procedure were correct acquiring of prastate ti ssue,more accurate approach and depth of the puncturing needle,avoiding injury t o the nearby tissue and raising the diagnosis rate of prostatic carcinoma.
