近年来,我国前列腺癌的发病率呈逐年增高的趋势~([1])。经直肠超声(transrectal ultrasound,TRUS)不仅是目前临床最常用的前列腺癌影像学筛查方法,同时也是前列腺穿刺最常用的引导方法。对TRUS有可疑目标的患者,经会阴途径TRUS引导的前列腺穿刺可采用系统穿刺(6~10点)加目标穿刺(X点)的穿刺方案;而对TRUS阴性的患者,在无其它影像学资料支持的情况下只能采用系统穿刺法。研究显示,约20%~30%的前列腺癌发生在移
In recent years, the incidence of prostate cancer showed a trend of increasing year by year ~ ([1]). Transrectal ultrasound (TRUS) is not only the most commonly used screening method for prostate cancer in clinic, but also the most commonly used method of prostatic biopsy. For patients with suspicious targets for TRUS, transperitoneal TRUS-guided prostatic biopsies may be performed using the puncture protocol (6 to 10 points) plus targeted punctuation (point X), whereas in TRUS-negative patients, no other imaging data Only support system puncture method. Research shows that about 20% to 30% of prostate cancer occurs in the shift
