摘　　要：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 evaluate the clinical value of transrectal ultrasound (TRUS) examination of the prostate in the diagnosis of prostatic cancers (PC) .Methods Fifty-three patients with prostatic cancer were examined with TRUS. The echoes of the outer and inner gland were observed to distinct the relationship between abnormal sharp hypoechoes and the surrounding tissures with color Doppler flow imaging (CDFI) or power Doppler imaging (PDI). Results Forty-six cases of PC were confirmed by biopsy and pathology, the other 7 had hyperplasia of prostate. The dignostic accuracy rate was 86. 8%. Conclusions Ultrasonography has more high sensitivity and specifity than those of abdominal ultrasonography. TRUS combined with digital rectal examination (DRE) and PSA can improve the dignostic acuracy rate of PC.
