目的 为进一步提高早期诊断前列腺癌的准确率。方法 应用经直肠超声对临床拟诊 2 1例前列腺癌患者进行检查 ,观察前列腺内腺及外腺回声 ,发现形态不规则低回声区 ,仔细分辨与周围组织关系 ,特别是与精囊的关系。结果 经穿刺活检及手术病理诊断 19例为前列腺癌 ,2例为前列腺增生。结论 经直肠超声显示前列腺癌声像图的特征性、敏感性较腹部超声检查明显提高 ,尤其是病灶小 ,直肠指检及 CT检查均为阴性 ,对前列腺特异性抗原 (PSA)增高患者经本法检查更能体现其优越性 ,能显示 <0 .5 cm病灶 ,可指导穿刺活检 ,不失为对前列腺癌早期诊断的一种可靠方法。
The purpose is to further improve the accuracy of early diagnosis of prostate cancer. Methods Twenty-one cases of prostate cancer were retrospectively studied by transrectal sonography. The echogenicity of the gland and the gland of the prostate was observed. The irregular hypoechoic region was found and the relationship with the surrounding tissues was carefully distinguished, especially the relationship with the seminal vesicle. Results of biopsy and surgical pathological diagnosis of 19 cases of prostate cancer, 2 cases of benign prostatic hyperplasia. Conclusion The transrectal ultrasonography showed that the characteristic and sensitivity of sonography of prostate cancer was significantly higher than that of abdominal ultrasonography, especially the small lesions, the negative digital rectal examination and the CT examination. All the patients with benign prostate-specific antigen (PSA) Law examination can better reflect its superiority, can show <0. 5 cm lesions, can guide the biopsy, after all, is a reliable method of early diagnosis of prostate cancer.
