目的探讨经直肠超声检查前列腺癌的临床价值。方法应用经直肠超声对临床拟诊53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的关系,并行彩色及能量多普勒血流显像。结果经穿刺活检及手术病理证实46例为前列腺癌,7例为前列腺增生,诊断符合率为86.8%。结论经直肠超声显示前列腺癌声像图的敏感性及特征性较腹部超声明显增高,结合直肠指检(DRE)及前列腺特异性抗原(PSA)测定可提高前列腺癌的检出率。
Objective To investigate the clinical value of transrectal ultrasound in the diagnosis of prostate cancer. Methods 53 patients with suspected prostate cancer were examined by transrectal ultrasound. The echoes of the gland and gland of the prostate were observed. The irregular hypoechoic region was found and the relationship with the surrounding tissue was carefully distinguished. The color and energy Doppler blood Flow imaging. Results The biopsy and surgical pathology confirmed 46 cases of prostate cancer and 7 cases of benign prostatic hyperplasia. The diagnostic coincidence rate was 86.8%. Conclusion The transrectal ultrasonography showed that the sensitivity and characteristic of sonography of prostate cancer were significantly higher than that of abdominal ultrasonography. Combined with digital rectal examination (DRE) and prostate specific antigen (PSA), the detection rate of prostate cancer could be increased.
