摘要
目的探讨前列腺癌声像图特征,提高前列腺癌活检阳性率.方法对血清PSA>4 ng/mL或直肠指检异常的患者行经直肠超声引导下前列腺穿刺活检,不同穿刺部位的标本分别标记送病理检查,对102例确诊为前列腺癌的患者的病理结果与声像图对照分析.结果 102例患者中二维声像图未提示明显异常38例(占37%),前列腺外周带或移行带见结节26例(占25%),外周带、移行带分界不清30例(占29%),前列腺见明显低回声团块8例(占8%).彩色多普勒显示:未见明显异常75例,局部血流汇聚或血管绕行8例,血流弥漫性增多10例,血流减少9例.二维声像图和彩色多普勒对显示前列腺癌的敏感性分别为63%(64/102)和26%(27/102).结论前列腺外腺低回声结节、前列腺内外腺界不清、前列腺团块、彩色血流汇聚或绕行的结节均高度提示前列腺癌,是穿刺活检的重点.
Objective To study the ultrasonographic features of the prostate carcinoma and improve the positive rate of prostate biopsy.Method The patients who had either serum PSA>4 ng/mL or abnormal findings of digital rectal examination underwent transrectal ultrasound guided biopsy and the biopsy samples were respectively marked.102 patients with prostate carcinoma proved by pathology were studied by comparison between the pathology and ultrasonography.Results Among the 102 patients,38 cases(37%)had no significant abnormal ultrasonography,26 cases(25%)were detected with nodes,30 cases(29 %)displayed nonuniform and unborder between the peripheral zone(PZ)and transitional zones(TZ),another 8 cases(8%)were detected low-echo masses.Color Doppler imaging showed normal in 75 cases,flows gathering or passing round at the node in 8 cases,widespread increasing in 10 cases and decrease in 9 cases.The sensitivity value of ultrasonography and color Doppler imaging respectively were 63%(64/102)and 26%(27/102).Conclusions The prostate carcinoma is highly doubted in the case of following ultrasonographies:low-echo-node in the peripheral zone;unclear border;transitional zone;low-echo mass of the prostate and the nodes of the prostate where color flow gather or pass round.These are the focal point of prostate needle biopsy.
