资料与方法：对43例健康婴儿4小时的排尿方式，包括排尿次数、排尿量、膀胱容量和剩余尿量进行无创测定。结果：患儿平均每小时排尿1次，但差异较大。膀胱容量随年龄增长按38 + 2.5 ×年龄（月）计算。平均残尿正负标准差为4.6±3.0 ml。所有婴儿的残尿量均小于5 ml，观察期间至少一次。结论：4小时排尿观察是一种简单、无创的排尿方式表征方法，尤其适用于婴儿和未训练如厕的儿童排尿困难。
Purpose: We present the 4-hour voiding observation as a method for basic assesMaterials 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.
