摘　　要：目的探讨经直肠弹性成像在协助前列腺癌穿刺活检中的应用价值。方法选取125例前列腺特异抗原升高患者，行经直肠超声引导前列腺穿刺活检。每例患者先常规穿刺8个点，并选择弹性成像提示较硬的前列腺组织处活检2个点，记录弹性成像显示的每个穿刺点硬度，并根据硬度值将活检部位分为高硬度组和低硬度组，比较两组活检组织的病理结果。结果125例患者病理结果提示87例（67．9％）为前列腺增生，38例（32．1％）为前列腺癌。125例患者共活检1250针，每例患者弹性检查花费时间10～16min（平均为13．2±2．8min），高硬度组和低硬度组分别437个和813个，两组中病理提示为癌的分别为131个和162个，其中高硬度组的前列腺癌检出率明显高于低硬度组（P〈0．01）。结论经直肠弹性成像可提高前列腺癌的活检检出率。Objective To evaluate the value of transrectal real-time tissue elastography （TRTE） in transrectal prostate gland biopsy. Methods Totally 125 male patients with elevated prostate specific antigen were chosen for transrectal prostate gland biopsy. Eight points as well as two points that TRTE shown as hard tissue were punctured for each patients. According to the TRTE results, all the punctured points were divided into hard tissue or soft tissue. The pathologic results between the hard tissue and soft tissue were compared. Results Eighty-seven patients （67.9%） were diagnosed as benign prostatic hyperplasia and 38 （32.1%）as prostate cancer. Altogether 1250 biopsy tissues were taken and the time spent for TRTE in each patient was 10-16 min 03.2±2.8 rain in average）. Biopsy tissues shown 437 and 813 in hard and soft group, the case with the prastate cancer was 131 and 162 respectively. The hard tissue group had higher prastate cancer rate than the soft tissue group （P=0.00）. Conclusions Transrectal real-time tissue elastography could be a new method to improve the transreetal prostate gland biopsy for cancer.
