超声引导下经直肠前列腺穿刺活检术的临床应用

目的 探讨经直肠超声引导前列腺穿刺活检术诊断前列腺癌的临床价值.方法 对69例直肠指诊阳性或PSA＞4ng/ml及前列腺B超有异常低回声结节病例,在行前列腺系统十点穿刺活检术同时对可疑回声区随机增加穿刺点.结果 共检出前列腺癌21例,占30.43%,前列腺良性增生并前列腺炎40例,占59.97%,前列腺炎5例,占5.80%,前列腺囊肿1例,占1.45%,前列腺不典型增生2例,占2.90%,随机增加穿刺活检检出7例,占10.15%,复检穿刺出前列腺癌3例,占4.35%.结论 前列腺穿刺活检为前列腺癌早期诊断的重要手段,经直肠超声引导定位准确,可随机增加穿刺点,能够提高前列腺癌检出率,无严重并发症.

Clinical Application of Transrectal Ultrasound Guided Prostate Biopsy in Diagnosing Prostate Carcinoma

Objective To explore the values of transrectal ultrasound(TRUS)guided biopsy of the prostate cancer.Methods Systematic 10 core prostate biopsy and option adding biopsy was performed on 69 patients who had prostate specific antigen(PSA)more than 4 ng/ml,or who had suspected prostate nodules on ultrasound or by digital rectal examination(DRE).Results 21 cases(30.43%)were prostate cancer,benign prostatic hyperplasia(BPH)with prostatitis were detected in 40 cases(59.97%);prostatitis 5 cases(5.80%);cyst of prostate 1 case(1.45%);prostatic light atypical hyperplasia 2 cases(2.90%);option adding biopsy 7 cases(10.15%)prostate carcinoma;3 cases(4.35%)prostate carcinoma was gained with biopsy again.Conclusion Biopsies of the prostate guided by transrectal ultrasound are helpful in early diagnosis of prostate carcinoma.transrectal ultrasound guided biopsy is accurate in locating.No patient had severe complications after biopsy.
