前列腺增生行电切术后其特异性抗原浓度变化的研究

目的：探讨良性前列腺增生（BPH）病人行标准经尿道前列腺电切术（TURP）后其前列腺特异性抗原（PSA）值的变化。方法：采用放射免疫法对62例因BPH而行标准TURP的病人术前及术后3～4个月的PSA进行测定。结果：PSA值由术前的4．3μg／L降为1．8μg／L，平均减少58％．前列腺体积由术前的46．5ml减少为24．4ml，平均减少48％，相当于每切除1g前列腺组织，PSA下降0．11μg／L；术后有84％的病人PSA值＜4μg／L，97％的病人＜10μg／L。结论：BPH行标准TURP后，其PSA值应在正常参考范围内，即＜4μg／L。

The study of PSA concentration after TURP of BPH

Objectives: To study the prostate specific antigen(PSA) concentration in benign prostate hyperplasia (BPH). Methods: PSA was determined preoperatively and 3~4 months postoperatively in 62 BPH patients who underwent standard TURP. Results:Mean PSA levels were reduced by 58%, from 4. 3 μg/L to 1. 8 μg/L. Prostate volume was reduced by 48%, from 46. 5 ml to 24. 4 ml. 84% BPH patients had a postoperative PSA concentration of less than 4 μg/L and 97% less than 10μg/L. Conclusions:After a standard TURP with BPH, PSA concentration should be expected to be within the normal (reference) range (less than 4 μg/L ).
