Bedwetting is present in 5 to 7% of children aged 7 to 8 years. The hi
story of the disorder and the examination of the child are of main imp
ortance. This is usually the first step to identify nocturnal enuresis
, bladder or urethral instability and other voiding dysfunctions. Ther
apeutic failure is often related to an inadequate analysis of the diso
rder. For nocturnal enuresis, the best results are obtained with alarm
s and/or desmopressine; bladder instability usually requires oxybutini
ne chlorydrate and urethral instability can be treated with biofeedbac
k therapy. The management of other voiding dysfunctions depends on uro
dynamic assessment.
