目的:探讨前列腺总体积(TV)和移行区体积(TZV)与年龄和性激素之间的关系。 方法:82例男性分为 两组,A组31例,年龄≤59岁,B组51例,年龄≥60岁,采用经直肠前列腺超声测定前列腺TV、TZV,采用放射免疫 法测定血清中总睾酮(T)、游离睾酮(fT)、雌二醇(E2)浓度。应用指数回归分析法和单因素方差分析法(ANOVA) 进行统计学分析。 结果:年龄与前列腺TV、TZV,TZV/TV比值差异有显著性(P<0.01);fT浓度与TZV呈显著 正相关性,E2浓度与TZV呈负相关性(P均<0.01),而T的浓度变化与TZV大小无明显的相关性(P>0.05)。 结论:TZV在60岁后有明显加速增长趋势,与血清中性激素浓度有关。
Objective: To investigate the relationship between total prostate volume (TTV) and transit volume (TZV) and age and sex hormones. Methods: 82 male patients were divided into two groups: group A, 31 cases, age ≤59 years, group B, 51 cases, age ≥60 years. Prostate TVS and TZV were measured by transrectal sonography. Total testosterone (T), free testosterone (fT), estradiol (E2) concentration. Statistical analysis was performed using exponential regression analysis and one-way analysis of variance (ANOVA). Results: There was a significant difference between age and prostate TV, TZV, TZV / TV (P <0.01), fT concentration was positively correlated with TZV, E2 was negatively correlated with TZV (P <0.01) There was no significant correlation between the concentration of TZV and the concentration of TZV (P> 0.05). Conclusion: TZV significantly accelerates the growth after 60 years of age, which is related to the concentration of serum hormones.
