We describe the development of voiding patterns and bladder control in healthy children during the first 3 years of life.
We determined voiding patterns, bladder capacity and post-void residual urine volume per 4 hours individually and noninvasively every 3 months in 36 female and 23 male healthy infants using the 4-hour voiding observation.
Voiding frequency decreased slowly from 5 to 2 voiding episodes per 4 hours from ages 3 months to 3 years. We noted interrupted voiding in 33% of subjects at age 3 months but this condition was rare after age 2 years. Voiding during sleep occurred mainly during the first 7 months of life and did not continue after age 18 months. Bladder capacity increased from a median of 52 to 67, 68 and 123 ml. during years 1 to 3, respectively. As measured by post-void residual urine volume, bladder emptying was unchanged during years 1 and 2 but it decreased during year 3 (median 6 versus 0 and mean 4 versus 3 ml. per 4 hours).
During the first 3 years of life the number of voiding episodes, including interrupted voiding, post-void residual urine and voiding during sleep, decreased while bladder capacity increased.
我们描述了健康儿童在生命的头3年中排尿模式和膀胱控制能力的发展情况。
我们对36名健康女婴和23名健康男婴使用4小时排尿观察法，每3个月单独且无创地确定一次每4小时的排尿模式、膀胱容量和排尿后残余尿量。
排尿频率从3个月大到3岁时每4小时排尿次数从5次缓慢下降到2次。我们注意到3个月大时33%的受试者存在间断排尿，但2岁后这种情况很少见。睡眠中的排尿主要发生在生命的前7个月，18个月后不再继续。膀胱容量在1岁到3岁期间分别从52毫升中位数增加到67毫升、68毫升和123毫升。通过排尿后残余尿量测量，1岁和2岁时膀胱排空情况无变化，但3岁时下降（每4小时中位数6毫升对0毫升，平均4毫升对3毫升）。
在生命的头3年中，包括间断排尿、排尿后残余尿量和睡眠中排尿在内的排尿次数减少，而膀胱容量增加。
