良性前列腺增生患者前列腺体积和移行区体积随年龄变化的调查

目的:调查良性前列腺增生(BPH)患者各年龄段前列腺总体积(TPV)、前列腺移行区体积(TZV),计算TZV与TPV的比值即移行区指数(TZI)的数值。分析年龄与上述指标的相关性。方法:经直肠B超测量1 563例BPH患者前列腺和前列腺移行区最大左右径、前后径和上下径,根据公式分别计算出TPV、TZV以及TZI。分析年龄与前列腺体积各参数的相关性。结果:BPH患者各年龄组TPV、TZV和TZI值分别为:50~59岁年龄组TPV(32.27±15.76)ml、TZV(9.55±7.98)ml、TZI 0.28±0.13;60~69岁年龄组TPV(40.93±17.45)ml、TZV(14.94±11.83)ml、TZI 0.34±0.16;70~79岁年龄组TPV(46.56±20.31)ml、TZV(19.54±19.25)ml、TZI 0.39±0.16;80~89岁年龄组TPV(47.85±26.63)ml、TZV(20.40±16.78)ml、TZI 0.41±0.19。BPH患者的TPV、TZV与年龄成显著正相关性(r1=0.232,r2=0.256,P均<0.01),TZV与年龄的相关系数要高于TPV与年龄的相关系数。结论:BPH患者的TPV、TZV值随着年龄的增长而增加,但是TZV增长的幅度要高于TPV增长的幅度,前列腺增生以移行区增生最为显著,并且我国BPH患者的移行区指数与其他人种之间可能存在不同。

Volumes of Total Prostate and Transitional Zone Are Positively Correlated with Age in Benign Prostatic Hyperplasia Patients

Objective:To investigate the total prostate volume(TPV) and prostate transitional zone volume(TZV) in different age groups of benign prostatic hyperplasia patients,calculate the transitional zone index(TZI),and analyze correlation of age with the above parameters.Methods:We divided 1 563 BPH patients into 4 age groups(50-59,60-69,70-79 and 80-89 y),measured their TPV and TZV by rectal ultrasonography,calculated their TZI and evaluated all the data obtained by statistical analysis.Results:The TPV,TZV and TZI...
