目的：探讨前列腺增生患者的血清特异性抗原升高的影响因素。方法：将来我院就诊的170例前列腺增生患者按照血清前列腺特异性抗原（PSA ）值分为A、B、C三组，分析患者的年龄、前列腺体积、国际前列腺症状评分（IPSS ）、残余尿和前列腺炎与血清PSA之间的关系，并对可能的影响因素做了多元回归性分析。结果：前列腺增生患者的年龄、前列腺体积、IPSS、残余尿和前列腺炎是影响血清PSA的因素，经过多元回归分析显示，年龄、前列腺体积、IPSS和前列腺炎是其独立影响因素。结论：影响血清PSA 的危险因素有年龄、前列腺体积、IPSS、残余尿和前列腺炎，其中年龄、前列腺体积、IPSS和前列腺炎是影响血清PSA升高的独立危险因素。%Objective :Elevated serum of patients with benign prostatic hyperplasia specific antigen fac-tors were analyzed .Methods :Our hospital 170 cases of patients with benign prostatic hyperplasia in the future in ac-cordance with the serum prostate-specific antigen (PSA) value was divided into three groups A ,B ,C ,analysis of the patient's age ,prostate volume ,IPSS ,residual urine and prostatitis serum PSA relationship ,and the possible effects of factors do multiple regression analysis .Results :Prostatic hyperplasia patients age ,prostate volume ,IPSS , residual urine and prostatitis influence factors of the serum PSA after multiple regression analysis showed that age , prostate volume ,IPSS and prostatitis independent impact factors .Conclusion:Affect serum PSA ,age ,prostate vol-ume ,IPSS ,residual urine and prostatitis risk factors ,including age ,prostate volume ,IPSS and prostatitis is an in-dependent risk factor for elevated serum PSA .
