Nocturnal enuresis is a multifactorial condition and, as such, is acce
ssible to a variety of treatment modalities. In order to evaluate and
compare the efficacies of different treatments in patients with specif
ic pathophysiologies, studies should describe fully the patient popula
tion under investigation. In addition, many of the studies conducted t
o date have applied different outcome measures, making comparisons dif
ficult. Therefore, it is necessary to define standard outcome measures
that should be used universally. These may relate to the effect of th
e treatment on the number of wet nights per week, the effect on the fa
mily economy of a reduction in the number of episodes of enuresis and
the effect on the child's self esteem and/or quality of life.
