目的 :揭示老龄人群前列腺增生的发病现状及血清睾酮水平的变化规律。方法 :以一汽集团 5 0岁以上男性为研究对象 ,另设 2组年龄对照 ,均行直肠指诊、经腹前列腺超声检查、放免技术测定血清睾酮与皮质醇含量。结果 :(1) 5 0岁以上人群中BPH发现率 ,直肠指诊诊断率为 6 0 0 5 % ,经腹超声诊断率为 6 9 5 7% ,并且随增龄明显增高 ;(2 )血清睾酮含量随增龄下降 ,二者间呈明显的负相关关系 (r =- 0 45 ,P <0 0 0 0 1) ;(3)前列腺体积与血清睾酮含量呈显著的负相关关系 (r =- 0 2 2 4,P <0 0 0 1)。结论 :在 5 0岁以上人群中BPH的发现率超过6 0 % ,并发现BPH的发病可能与血清睾酮含量下降有关。
Objective: To reveal the incidence of benign prostatic hyperplasia in elderly population and the change of serum testosterone levels. Methods: Taking FAW Group male over 50 years old as the research object, two groups of age control subjects were also enrolled in the rectal examination. The serum testosterone and cortisol levels were determined by abdominal ultrasonography and radioimmunoassay. Results: (1) The prevalence of BPH, rectal examination and rectal ultrasound were 50% and 50% respectively. The diagnostic rate of transabdominal ultrasound was 69.57%, which was significantly higher with age. (2) Serum There was a significant negative correlation between testosterone and aging (r = - 0 45, P 0 01 0). (3) There was a significant negative correlation between testosterone and serum testosterone (r = - 0 2 2 4, P <0 0 0 1). CONCLUSIONS: The prevalence of BPH was over 60% in people over 50 years of age and found that the incidence of BPH may be related to a decrease in serum testosterone levels.
