经直肠前列腺穿刺活检161例临床分析

Clinical analysis of transrectal prostate biopsy(report of 161 cases)

目的评估经直肠前列腺穿刺活检在前列腺癌及前列腺其他疾病的诊断和鉴别诊断的价值。方法对直肠指诊阳性、血清PSA>4μg/L及超声检查前列腺声像图异常怀疑有占位性病变的161例患者进行经直肠的前列腺穿刺活检。结果穿刺活检的161例病理结果:良性前列腺增生(BPH)102例占63.35%,前列腺癌(PCa)50例占31.06%,前列腺炎7例占4.25%,前列腺高级别上皮内瘤变2例。结论经直肠前列腺穿刺活检其操作简单,并发症少,安全性高。在前列腺癌及其他前列腺疾病的诊断与鉴别诊断中有重要的临床价值。

Objective To evaluate the clinical diagnosis and differentiative diagnosis of transrectal prostatic biopsies utilized to detect prostate cancer （PCa） and other prostatic diseases. Methods Transrectal prostatic biopsy was performed on 161 patients whose digital rectal examination showed positive results, serum PSA over 4 μg/L, and ultrasound results showed unusual echo. Results The results showed 102 cases （63.35 % ）of benign prostate hyperplasia （ BPH ）, 50 （31.06% ） prostate cancer （PCa）, 7 （4. 25% ） prostatitis and 2 prostatic intra-epithelial neoplasia（PIN）. Conclusion Transrectal prostatic biopsy is convenient and safe, at the same time, patients have few complications. It can be a reliable assay in clinical diagnosis and differentative diagnosis of prostate diseases.
