经直肠二维及三维超声引导下前列腺系统性穿刺的比较

摘要

目的：比较经直肠二维及三维超声引导下前列腺穿刺活检的阳性率，评价这两种方法在临床应用中的价值。方法选取既往无前列腺癌病史的60例直肠指检或者前列腺特异抗原（PSA）异常（＞4.0ng/mL）的患者，随机分为两组，分别行2D-TRUS及3D-TRUS超声引导下的穿刺活检。结果3D-TRUS引导下的前列腺穿刺活检，其前列腺癌的阳性检出率高于2D-TRUS（50.0%∶36.7%），P=0.001，3D-TRUS阳性针数的比例明显高于2D-TRUS，P=0.000。结论3D-TRUS超声引导下的前列腺穿刺活检阳性检出率明显高于2D-TRUS。%Objective To compare the positive rate of per rectum two-dimensional and three-dimensional ultrasound guidance in prostatic systematicness puncture biopsy, to evaluate the value of clinical application of the two methods. Methods 60 patients with digital rectal examination or abnormal of prostatic specific antigen(PSA) (> 4.0ng/mL)without past medical history of prostate cancer were divided into two groups who were respectively actualized on prostatic systematicness puncture biopsy of two-dimensional and three-dimensional ultrasound guidance. Results The positive rate of prostatic cancer of 3D-TRUS(50.0%)in prostatic systematicness puncture biopsy was higher than which of 2D-TRUS(36.7%)(P=0.001), the number of positive needles of 3D-TRUS was obviously higher than which of 2D-TRUS(P=0.000). Conclusion The positive rate of 3D-TRUS in prostatic systematicness puncture biopsy was higher than which of 2D-TRUS.
