经直肠超声引导下经会阴前列腺改良穿刺法的价值

目的评价经直肠超声（transrectal ultrasonography，TRUS）引导下经会阴前列腺改良穿刺法在前列腺穿刺活检中的作用，以期寻找有助于提高前列腺癌（Prostatic Cancer PCa）检出率的手段或方法。方法对151例前列腺特异性抗原（prostate specific antigenPSA）升高（〉4ug／L）和（或）TRUS发现有结节的患者在经直肠超声引导下经会阴行前列腺改良穿刺活检，穿刺标本送病理检查。结果151例患者中，共检出PCa49例（32％），上皮内瘤12例（8％），慢性炎症48例（32％），良性增生42例（28％）。与标准系统穿刺法相比，改良穿刺法可将PCa的检出率提高18％。本组资料有25例（17％）的患者术后出现血尿，无其它并发症发生。结论经直肠超声引导下经会阴前列腺改良穿刺法，有助于提高PCa的检出率。

Transrectal Ultrasound Guided Perineal Prostatic Improved Biopsy

Objective To evaluate the application of transrectal ultrasound(TRUS)guided perineal prostatic improved biopsy in order to find out the methods to improve prostate carcinoma(PCa)detectable rate.Methods Totally 151 cases with high serum PSA (>4ug/L)and/or the abnormal nodules found by TRUS were examined by TRUR guided perineal prostatic improved biopsy.Results In 151 cases,49 with PCa (32%),12 with prostatic epithelial sarcoma(8%),48 with chronic prostatitis (32%) and 42 benign prostate hyperplasia (28%).The detectable rate of PCa improved biopsy was increased 18% higher than that of normal ordinary biopsy.Hematuria was found in 25 patients (17%) after operation,but no other complications were found.Conclusions The TRUS guided prostatic improved biopsy can increase the detectable rate of PCa.
