| 摘 要： | 目的 通过经直肠超声(TRUS)引导下的前列腺定点穿刺活检研究前列腺外腺低回声结节的性质。方法 42例患者因TRUS发现前列腺外腺低回声结节而疑患前列腺癌，行TRUS引导下结节定点穿刺活检，每个结节分别在纵向和横向上各穿刺1针。在双盲情况下进行病理诊断。结果 42例前列腺外腺低回声结节定点穿刺标本病理诊断前列腺增生症22例，占52．4％，前列腺癌20例，占47.6％。结论 TRUS发现的前列腺外腺低回声结节，除了前列腺癌之外，还包括良性增生结节，最终确诊有赖于病理学检查。

| Abstract: | Objective To study the characteristic of the hyperplasia hypoechoic nodules in outer gland of prostate with transrectal ultrasound (TRUS) guided biopsies. Methods 42 patients were suspected of prostatic cancer (PCa) for the existence of hypoechoic nodules in their outer glands of prostate. Each nodule was TRUS guided biopsied in sagittal and longitudinal section, respectively. The histological examinations were performed in double blind. Results Among the 42 patients, there were 22 cases of benign prostate hyperplasia (52.4%) and 20 cases of prostate cancer (47.6%). Conclusions The sonographic findings of the hypoechoic nodules in outer glands included not only PCa, but also benign hyperplasia nodules. Therefore, the definitive diagnosis must dependent on pathologic examinations. |
