PURPOSE
We present the 4-hour voiding observation as a method for basic assessment of bladder function in infants and nontoilet trained children.
MATERIALS AND METHODS
Voiding pattern, including number of voidings, voided volume, bladder capacity and residual urine for 4 hours, was determined noninvasively in 43 healthy infants.
RESULTS
The infants voided an average of 1 time per hour but with great variability. Bladder capacity increased with age according to the formula, 38 + 2.5 x age (months). Mean residual urine plus or minus standard deviation was 4.6 +/- 3.0 ml. In all infants residual volume was less than 5 ml. at least once during observation.
CONCLUSIONS
The 4-hour voiding observation is an easy noninvasive method of characterizing the voiding pattern, focusing especially on emptying difficulties, in infants and nontoilet trained children.
目的
我们提出4小时排尿观察法，作为对婴儿和未接受如厕训练儿童膀胱功能进行基本评估的一种方法。
材料与方法
对43名健康婴儿进行无创测定，确定其4小时的排尿模式，包括排尿次数、排尿量、膀胱容量和残余尿量。
结果
婴儿平均每小时排尿1次，但个体差异很大。膀胱容量根据公式“38 + 2.5×年龄（月）”随年龄增长。平均残余尿量加减标准差为4.6 +/- 3.0毫升。在所有婴儿中，观察期间至少有一次残余尿量小于5毫升。
结论
4小时排尿观察是一种简单的无创方法，可用于描述婴儿和未接受如厕训练儿童的排尿模式，尤其关注排尿困难情况。
