Brief summary

The aim of this study is to analyse urinary neurotrophin levels in healthy children. Urine samples will be collected at 3 different times of day (morning, noon, and evening) at urge sensation from all age groups of children who gained bladder control, i.e. from 3-18 years of age. Urinary levels of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) normalised to urinary creatinine will be analysed. Age and daytime related variations will be reported for both boys and girls. These results will contribute to understanding the role of neurotrophins in the physiology of lower urinary tract and pathophysiology of idiopathic and secondary hyperactive bladder in children.

MeasureTime frameDescription
Concentration of urinary nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) normalised to urinary creatininCollection of urine samples and analysis will take approximately 6 months.We will collect urine samples from healthy children without lower urinary tract symptoms and analyse urine concentrations of neurotrophins (NGF and BDNF) normalised to urinary creatinin in order to report its normal age- and daytime-related variations.
