目的探讨经直肠超声前列腺穿刺12点穿刺法在前列腺癌诊断及鉴别诊断中的作用及其并发症分析。方法对血PSA>4ng/L、直肠指诊阳性及经直肠超声检查前列腺声像图异常回声23例病人行经直肠超声引导下前列腺穿刺活检术;在前列腺两侧旁正中线矢状切面尖部、中部和底部各穿刺3点,左右侧外周带各3点,对超声检查发现前列腺结节增加穿刺1点。结果 23例病理结果前列腺癌12例,占52%,前列腺增生9例,非典型小腺泡增生1例,前列腺炎1例。结论 B超引导下经直肠前列腺12点穿刺活检术对前列腺癌的检出率高、操作简便、患者痛苦小、并发症少,是临床诊断前列腺癌的一种快速、安全、有效的诊断方法。
Objective To investigate the role and complications of transrectal ultrasound prostate puncture 12-point puncture in the diagnosis and differential diagnosis of prostate cancer. Methods Twenty-three patients underwent echocardiography guided prostate biopsy under the condition of PSA> 4ng / L, positive rectal examination and transrectal ultrasonography. Echo-guided prostatic biopsy was performed in 23 patients. The middle and bottom of the puncture 3:00, left and right side of the peripheral zone with 3 points on the ultrasound examination of the prostate nodules increased puncture 1:00. Results The pathological results of 23 cases of prostate cancer in 12 cases, accounting for 52%, 9 cases of benign prostatic hyperplasia, atypical small acinar hyperplasia in 1 case, prostatitis in 1 case. Conclusions B-guided 12-point transrectal prostate biopsy is a fast, safe and effective method for the diagnosis of prostate cancer. The detection rate of prostate cancer is high, and the operation is simple. The patient has less pain and fewer complications.
