改良前列腺穿刺活组织检查技术的临床应用

The Clinical Application of Improved Prostate Biopsy Technique

目的探讨改良前列腺穿刺活组织检查(活检)技术对前列腺癌的检出率。方法对615例经直肠超声检查发现前列腺有可疑病灶的患者采用改良前列腺穿刺活检术,平均活检点数为8点。观察穿刺活检结果。结果患者均能耐受活检过程。615例患者中检出前列腺腺癌231例(37·6%),前列腺结节状增生358例(58·2%),前列腺炎症9例(1·5%)。结论经直肠超声引导经会阴前列腺外周带系统穿刺联合病灶直接活检技术可提高前列腺癌的检出率,且能被患者耐受。

Objective To evaluate the positive rate of prostate carcinoma by using improved prostate biopsy technique. Methods The improved prostate biopsy was performed in 615 patients, the cores obtained was 8 in average. Results All the patients could tolerate the approach, 231 patients were diagnosed as prostate carcinoma among 615 peoples （37. 6% ） ; 358 cases were as nodular hyperplasia of prostate （58. 2% ） ; 9 prostatitis （ 1. 5% ）. Conclusion Per rectum ultrasound guiding transperineal prostate peripheral zone systematic biopsy combined with direct biopsy technique of the focuses can increase the positive rate of prostate biopsy and be easily accepted by patients.
