Seventy-80% of prostatic carcinoma develops in the peripheral gland. Transrectal ultrasound (TRUS) has the capacity to identify nodules or hypoechogenic areas in the peripheral zone, suspected to be carcinoma. We describe a new echographic technic with endorectal probe (target compression test), to study hypoechogenic areas or nodules in the peripheral gland, during TRUS examination. Thirty-three patients, aged 49-77 years, with prostatic peripheral hypoechoic lesion at transrectal ultrasound, were studied. All patients underwent prostatic biopsy. Ten of the 11 positive patients (non compressible lesion) at the target compression test resulted to be affected by adenocarcinoma. Only 3 of the 22 negative patients (compressible lesion) at the target compression test resulted to be affected by adenocarcinoma. Even if our data have to be confirmed by further studies, they suggest that the target compression test may be a useful complementary test, during TRUS, in the evaluation of hypoechogenic areas in the peripheral gland.
70%至80%的前列腺癌发生在外周腺。经直肠超声（TRUS）能够识别外周区的结节或低回声区，怀疑为癌。我们描述了一种使用直肠内探头的新超声技术（目标压迫试验），以在TRUS检查期间研究外周腺中的低回声区或结节。对33例年龄在49至77岁、经直肠超声显示前列腺外周低回声病变的患者进行了研究。所有患者均接受了前列腺活检。在目标压迫试验中，11例阳性患者（不可压缩病变）中有10例被诊断为腺癌。在目标压迫试验中，22例阴性患者（可压缩病变）中只有3例被诊断为腺癌。即使我们的数据有待进一步研究证实，但它们表明目标压迫试验可能是TRUS检查期间评估外周腺低回声区的一种有用的补充检查。
