经B超监测健康成人膀胱残余尿量的比较

Use B-ultrasound Comparison of the Bladder Post-void Residual Volume between Healthy Adults

目的比较健常成人不同性别、年龄段膀胱残余尿量的差异。方法随机选择20～29岁年龄段(男19例、女19例)、30～39岁年龄段(男29例、女33例)、40～49岁年龄段(男22例、女30例)、50～59岁年龄段(男10例、女15例)健康成人计177例。经腹部B超扫查,测量排尿后膀胱的上下径、左右径、前后径,计算膀胱残余尿量(公式:V=0.5d1.d2.d3)。结果(1)同年龄组男、女膀胱残余尿量比较无显著差异(P>0.01);(2)女性各年龄组间膀胱残余尿量比较无显著差异(P>0.01);(3)男20～29岁、男30～39岁与男50～59岁年龄组膀胱残余尿量比较有显著差异(P<0.01),男性其余组组间比较均无显著差异(P>0.01)。结论同年龄段男女排尿姿势不同、解剖不同不会引起膀胱残余尿量差异,不同年龄段男性膀胱残余尿量会随年龄的增大而增加;女性膀胱残余尿量与年龄无关。

Objective make an approach to the differences in the bladder post-void residual volume of healthy adults of different sexes and of different age groups. Methods choose 19 men and 19 women from the 20-29 years age group;choose 29 men and 33 women from the 30-39 years age group; choose 22 men and 30 women from the 40-49 years age group;choose 10 men and 15 women from the 50-59 years age group, and all of the 177 healthy adults are selected at random. Apply abdominal B-ultrasound for scanning and inspection, measure the up-down, left-right and front-back diameters of the bladder respectively after emiction;derive the bladder post-void residual volume by the use of the formula：V= 0.5d1 · d2 · d3. Results （1） there are no significant differences in the bladder post-void residual volume between the male and the female groups of the same age（P〉0.01）;（2）there are no significant differences among those different female age groups in the bladder post-void residual volume （P0.01） ;（3）there are significant differences among the 20-29 years male group and the 30-39 years male group compared with the 50-59 years male group in the bladder post-void residual volume （P〈0.01） ; there are no significant differences among the other male age groups（P〉0.01）. Conclusion Different urinating postures of male or female subjects from the same age group as well as theoretic differences between Dhvsiology and structure anatomy would not result in differences in the bladder post-void residual volume. Bladder post-void residual volume of the male subjects from different age groups increases as the age grows. However, the age has nothing to do with the bladder post-void residual volume of the female subjects from different age groups.
