摘　　要：目的　探讨不同年龄段前列腺体积、移行带体积及移行带指数变化的临床意义。　方法　北京市某社区 2 13例 5 0～ 79岁男性 ,分为三个年龄段 ,采用经直肠超声测量前列腺体积、移行带体积 ,计算移行带指数 ,并对三组资料进行统计学分析。　结果　 5 0岁～、6 0岁～、70～ 79岁三个年龄段例数分别为 75、81、5 7例 ,前列腺总体积平均值分别为 (2 3.82± 8.83)ml、(2 9.16± 10 .0 1)ml、(33.77± 11.74)ml;移行带体积平均值分别为 (1.5 2± 1.19)ml、(3.6 0± 3.6 6 )ml、(7.2 5± 7.0 2 )ml;移行带指数平均值分别为 0 .10± 0 .12、0 .13± 0 .11、0 .2 0± 0 .11。统计分析显示三组间移行带体积及其指数差别有显著性意义 ,前列腺总体积差别无显著性意义。　结论　前列腺总体积、移行带体积随年龄增长而增加 ,移行带增长速度明显快于前列腺总体积 ,移行带指数反映了前列腺总体积、移行带体积的变化差异。Objective To study the volume of total prostate and the volume of its transitional zone in different age groups of elderly men. Methods 213 elderly men of 50 to 79 years of age from a community of Beijing city were divided into 3 groups and studied. The volume of total prostate and the volume of the transitional zone were measured by rectal ultrasonography and the index of the transitional zone was calculated. All the data were evaluated with statistical analysis. Results The number of subjects in the 50～59 age group was 75,in the 60～69 age group 81 and in the 70～79 age group 57.The volume of total prostate was 23.82±8.83,29.16±10.01 and 33.77±11.74 respectively and the transitional zone 1.52±1.19, 3.60±3.66 and 7.25±7.02ml respectively. The index of transitional was 0.10±0.12, 0.13±0.11, 0.20±0.11 respectively. The difference in volume of the total prostate has not been statistically significant whereas the difference in the volume of the transitional zone between the 3 age groups has been significant. Conclusions The volume of total prostate and that of the transitional zone increases with age. The speed of hyperplasia of the transitional zone has been faster than that of the whole prostate.The index of the transitional zone indicates the difference of the whole prostate and the transitional zone in hyperplasia.
