直肠超声引导下8点及12点前列腺穿刺活组织检查常见并发症比较

comparison of complications incidence of 8-and 12-core prostate biopsy guided with transrectal ultrasound

目的 比较8点及12点前列腺穿刺活组织检查术后的并发症发生情况,探讨减少相关并发症的措施.方法 回顾性分析260例直肠超声引导下前列腺穿刺活组织检查患者的相关资料,其中132例患者接受8点穿刺,128例患者接受12点穿刺.结果 260例患者中感染12例,其中8点组7例,12点组5例;肉眼血尿34例,其中8点组15例,12点组19例;直肠出血16例,其中8点组7例,12点组9例;急性尿潴留13例,其中8点组6例,12点组7例,两组患者并发症的发生率差异均无统计学意义（均P＞ 0.05）,但是当前列腺体积≥45 ml时,12点的前列腺癌检出率高于8点（P＜0.05）.结论 8点及12点穿刺的并发症发生率相当,采取针对性的措施可以明显降低前列腺穿刺活组织检查并发症的发生率,当前列腺体积较大时首选12点穿刺.

Objective To compare complications incidence rates of 8-core and 12-core prostate biopsies guided with transrectal ultrasound retrospectively,and to study intervention ways to decrease complications.Methods The data of 260 consecutive patients undergoing first-time transrectal ultrasound-guided biopsy were analyzed.132 patients underwent 8-core biopsy and 128 patients underwent 12-core biopsy.Results In 8-core group,there were 7 cases of infections,15 cases of gross hematuria,7 cases of rectal bleeding and 6 cases of acute urinary retention,and in 12-core group,5 cases of infections,19 cases of gross hematuria,9 cases of rectal bleeding and 7 cases of acute urinary retention in 12-core group.There are no statistical differences of complications incidence rate between two groups （P 〉 0.05）.when prostate volume 〉 45 ml,detection rate of prostate cancer in 12-core group was significantly higher than that in 8-core group.Conclusions There are no statistical differences of complications incidence rate between 8-and 12-core prostate biopsy.Homologous measure must be taken to reduce complications.12-core prostate biopsy is recommended as prostate volume 〉 45 ml.
