目的:评价经直肠超声引导下13针前列腺穿刺活检术在前列腺癌(PCa)诊断中的临床价值。方法:回顾性分析血清PSA>4ng/mL和(或)直肠指检前列腺结节及超声检查有异常的212例患者经直肠超声引导下13针前列腺穿刺活检的临床资料。其中直肠指诊异常者68例;超声显示有异常回声结节者63例。PSA<4.0ng/mL15例、PSA4.1-10ng/mL55例、PSA10.1-20ng/mL57例,PSA>20ng/mL85例。结果:212例活检中PCa72例,阳性率为32.6%,前列腺增生症140例。结论:经直肠超声引导下前列腺13针穿刺活检是诊断PCa的一种安全有效的检查方法。
Objective: To evaluate the clinical value of 13-pin prostatic biopsy guided by transrectal ultrasound in the diagnosis of prostate cancer (PCa). Methods: The clinical data of 13-needle biopsies guided by transrectal ultrasound guided by transrectal ultrasound were retrospectively analyzed in 212 patients with PSA> 4 ng / mL and / or digital rectal prostatic tract nodules and ultrasonographic abnormalities. There were 68 cases of abnormal digital rectal examination; 63 cases showed abnormal echo nodules by ultrasound. There were 15 cases of PSA <4.0 ng / mL, 55 cases of PSA 4.1-10 ng / mL, 85 cases of PSA10.1-20 ng / mL and PSA> 20 ng / mL. Results: There were 72 cases of PCa in 212 biopsies, the positive rate was 32.6% and the benign prostatic hyperplasia was 140 cases. Conclusions: Transrectal ultrasound-guided prostate biopsy of 13-pin needle is a safe and effective method for the diagnosis of PCa.
