摘　　要：目的探讨经直肠超声(transrectal ultrasonography,TRUS)引导并经直肠穿刺植入125I粒子技术的可行性及其在前列腺癌治疗中的应用。方法术前运用TRUS对本组42例前列腺癌患者进行前列腺体积研究;通过治疗计划系统(treatment plan system,TPS)制定计划;采用TRUS引导经直肠穿刺将125I粒子植入前列腺实施治疗方案;术后多排螺旋CT扫描判断粒子分布情况并作剂量分布评估,定期随访治疗效果和并发症情况。结果42例患者手术顺利完成,无因经直肠穿刺引起的严重并发症;术后运用CT扫描见粒子分布符合预定计划;剂量分布评估满意。结论TRUS引导经直肠穿刺125I粒子植入治疗前列腺癌技术简便快速、安全有效。Objective To discuss the technic and application of transrectal ultrasonography （TRUS） in per- rectum and ^125I seeds implantation and the treatment of the prostate cancer. Methods The prostatic volume of forty-two cases with prostate cancer were investigated by transrectal ultrasonography guidance pre operation. The treatment plan was established on the treatment Plan System （TPS） . ^125I seeds implantation was implemented through transrectal ultrasonography guidance. The ^125I seeds distribution and dose distribution were evaluated by multi-row spiral computer tomography （CT） . Regular follow-up and complication information were carried out after operation. Results The operations of forty-two cases with prostate cancer were completed successfully. No severe compIication appeared through per-rectum ^125I seeds implantation, The ^125I seeds distribution and dose distribution were in accord ance with the treatment plan by CT scan. Conclusions The technology of per-rectum ^125I seeds implantation in the treatment of prostate cancer is convenient, safe and efficient.
