title: Bladder function in infants.
abstract: 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.
