title: Enuresis, sleep and desmopressin treatment.
abstract: OBJECTIVE
  To detect effects of desmopressin on sleep in enuretic children and to look for polysomnographical differences between responders and non-responders to desmopressin treatment.
  
  
  METHODS
  Twenty-one children with primary nocturnal enuresis were examined polysomnographically before treatment. All but one of the children then received treatment with desmopressin in standard dosage, and the response was documented. Seven of the children underwent a second polysomnographic registration while on treatment.
  
  
  RESULTS
  The time interval (+/- 1 SD) between sleep onset and the enuretic episode was 92 +/- 67 min without medication and 372 +/- 157 min when desmopressin was given (p = 0.003). Standard polysomnographic variables were not affected by the drug. Ten children were desmopressin responders and 10 were non-responders. The total sleep time was 455 +/- 56 min in the former and 408 +/- 31 min in the latter group (p = 0.04). The responders spent 27.4 +/- 5.5% of their total sleep time in rapid eye movement sleep, compared with 18.2 +/- 6.5% in the non-responder group (p = 0.004).
  
  
  CONCLUSIONS
  Desmopressin has no major effects on sleep as such but does delay bladder emptying. Enuretic children responding to desmopressin treatment have more rapid eye movement sleep than therapy-resistant children.
