The purpose with the present review was to describe what could be considered as normal urodynamic findings in neonates and infants. During the first months of life, urodynamics were characterised by small bladder capacity and high voiding pressure levels, the latter especially marked in male infants. Also dyscoordination at voiding was a common finding. However, detrusor overactivity (unstable contractions) during filling was uncommon in infants. Towards the end of infancy, findings became more in accordance with what is seen in older children. Concluding these findings concerning urodynamic pattern in early infancy high voiding pressure levels must be looked upon as normal and the same is true for intermittent increase in activity in the pelvic floor during voiding. However, instability during filling is rarely seen.
本综述的目的是描述新生儿和婴儿中可被视为正常尿动力学检查结果的情况。在生命的最初几个月，尿动力学的特征是膀胱容量小和排尿压力水平高，后者在男婴中尤为明显。排尿时的不协调也是常见的表现。然而，婴儿在膀胱充盈期出现逼尿肌过度活动（不稳定收缩）的情况并不常见。在婴儿期接近尾声时，检查结果变得更符合大龄儿童的情况。总结关于婴儿早期尿动力学模式的这些发现，高排尿压力水平必须被视为正常，排尿时盆底活动的间歇性增加也是如此。然而，膀胱充盈期的不稳定情况很少见。
