回顾性研究了经直肠手指引导前列腺穿刺活检或细针抽吸的方法，对59例临床上怀疑为前列腺癌的病人作诊断性检查。结果发现前列腺癌的总阳性率为56％，其中前列腺穿刺活检为54．5％，细外抽吸为60％，两种不同的取材活检结果无明显差异（P＞0．05）。但细针抽吸的并发症少，适应证广。如果能在直肠指检的基础上结合超声波和血清前列腺特异抗原检查的材料来选择活检的适应证，则可使活检的阳性率提高到83％。
A retrospective study of transrectal finger-guided prostate biopsy or fine needle aspiration was performed on 59 patients with clinically suspected prostate cancer as a diagnostic test. Results found that the total positive rate of prostate cancer was 56%, of which prostate biopsy was 54.5%, and fine external suction was 60%. There was no significant difference in the results of two different biopsy samples (P>0.05). However, there are few complications of fine needle aspiration, which can be widely used. If the biopsy indication can be selected on the basis of digital rectal examination combined with ultrasound and serum prostate specific antigen, the positive rate of biopsy can be increased to 83%.
