Objective To discuss the technic and application of transrectal ultrasonography(TRUS)in per-rectum and ~(125)I 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).~(125)I seeds implantation was implemented through transrectal ultrasonography guidance.The ~(125)I 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 complication appeared through per-rectum ~(125)I seeds implantation.The ~(125)I seeds distribution and dose distribution were in accordance with the treatment plan by CT scan.Conclusions The technology of per-rectum ~(125)I seeds implantation in the treatment of prostate cancer is convenient,safe and efficient.
