经直肠直视下穿刺法在前列腺穿刺活检中的应用

目的探讨经直肠直视下前列腺穿刺活检方法的可行性。方法采用改良的俯卧位前列腺直视下穿刺方法行经直肠前列腺穿刺活检56例。利用庤上黏膜环形缝扎器（PPH）套件中的部分组件，即环形肛管扩张器及镜芯、肛镜缝扎器以协助显露直肠段前列腺。结果经直肠直视下前列腺穿刺活检方法可直视穿刺，穿刺深度和方向易控制。针刺布局规范，患者体位舒适，耐受适应好。无严重并发症发生。穿刺效果良好。结论经直肠直视下俯卧位前列腺穿刺活检方法简便，穿刺准确，值得推广。

Application of direct puncture of prostate in prostate biopsy

Objective To evaluate the feasibility of prostate biopsy under direct vision. Methods 56 patients recieved transrectal prostate biopsy under direct vision with a modified prone position.We used dilator and anal mirror suture device （parts of the PPH kit）to help revealing the prostate. Results Transrectal prostate biopsy under direct vision could achieve a very good view of prostate and made puncture easier by controlling the depth and direction.The puncture located well. The patient＆#39;s position was comfortable.The procedure were well tolerated in all patients.No serious complications occurred. Conclusions Transrectal prostate biopsy under direct vision with a modi-fied prone position is simple and accurate.It might be generalized in the future.
