目的 总结３ ２ Ｐ 介入法治疗前列腺增生症的疗效。 方法 采用介入法将放射活性１８５ ～４４４ Ｍ Ｂｑ 的３ ２ Ｐ 置入４１ 例前列腺增生组织内。 结果 随访２ 年。临床组３６ 例中的３１ 例国际前列腺症状评分（ Ｉ Ｐ Ｓ Ｓ） 、前列腺体积、剩余尿量及最大尿流率均有明显改善；病理组５ 例的前列腺增生组织纤维化萎缩。 结论 前列腺增生组织对放射线的敏感性较高，利用介入法行腺体内３ ２ Ｐ 辐射，可有效抑制增生组织的生长。
Objective To summarize the therapeutic effect of 3 2 P intervention on benign prostatic hyperplasia. Methods Thirty-two benign prostatic hyperplasia tissues with radioactive 185 ~ 444 M Bq were implanted by intervention method. The results were followed up for 2 years. Thirty-one cases in the clinical group had significantly improved I P S S, prostate volume, residual urine volume and maximal uroflow rate. In the pathological group, benign prostatic hyperplasia was observed in 5 cases. Conclusions The benign prostatic hyperplasia tissue is highly sensitive to radiation. Using interventional radiotherapy of 3 2 P in gland can effectively inhibit the growth of hyperplastic tissue.
