Aim. The aim of this paper was to examine the early morning spot urine osmolality and some other parameters easily detected from home chart recordings and history as predictive of the therapeutic response to desmopressin in children with monosymptomatic nocturnal enuresis.
Methods. Sixty seven monosymptomatic nocturnal enuretic children were included in the study. Age, sex, family history, the number of family members and siblings, existence of urgency symptoms, the history of urinary tract infection, sleep patterns, the number of wet nights per month and bedwetting in the same night were recorded. Additionally, spot morning urine osmolality was examined. All children were given desmopressin for at least 2 months. At the end of the treatment period, patients considered as responders and non-responders were compared in all these parameters.
Results. Although there was considerable overlap between groups, lower spot urine osmolality was the only data we found statistically significant as predictive of response to desmopressin. Moreover, male predominance, fewer wet nights per month and bedwetting per night were also associated with a better response.
Conclusion. We believe that it is important to characterize such different subgroups that could be used as predictors of a good response to desmopressin.
