目的 探讨经直肠超声引导 13点前列腺系统穿刺活检术诊断前列腺癌的临床价值。 方法 对 160例直肠指诊阳性和 (或 )PSA >4ng/ml的患者行经直肠超声引导 13点前列腺系统穿刺活检术。即在标准的经直肠超声引导 6点前列腺系统穿刺活检术同时 ,增加前列腺中间部位及前列腺两侧旁正中线远侧的穿刺点数 ,共穿刺活检 13点。将增加的 7点活检部位病理结果与标准的 6点前列腺系统穿刺活检术进行比较。 结果 160例患者中确诊为前列腺癌者 5 6例 ( 3 5 % )。 5 6例患者如按 6点穿刺方法 ,将有 12例患者漏诊 ,占 2 1%。 160例患者均未出现严重并发症。 结论 经直肠超声引导 13点前列腺系统穿刺活检术可明显提高前列腺癌的临床检出率
Objective To investigate the clinical value of transrectal ultrasound-guided 13-point prostate biopsy in the diagnosis of prostate cancer. Methods One hundred and sixty patients with positive and / or PSA rectal examinations underwent transrectal ultrasound guided 13-point prostate biopsy. That is, in the standard transrectal ultrasound guided 6-point prostate biopsy at the same time, increase the middle of the prostate and prostate on both sides of the median line next to the puncture point, a total of biopsy 13 points. The pathological results of the increased biopsy site at 7 points were compared with the standard 6-point prostate biopsy. Results Of the 160 patients, 56 were diagnosed as prostate cancer (35%). Fifty-six patients underwent 6-point puncture and missed diagnosis of 12 patients, accounting for 21%. None of the 160 patients experienced serious complications. Conclusion Transrectal ultrasound guided 13-point prostate biopsy can significantly improve the clinical detection rate of prostate cancer
