title: Desmopressin in the treatment of nocturnal polyuria in the male.
abstract: OBJECTIVE
  To assess whether desmopressin (1-desamino 8-d-arginine vasopressin) is safe and effective in the treatment of nocturnal polyuria in elderly men.
  
  
  METHODS
  Twenty men (age 52-80 years) complaining of nocturia were found to have nocturnal polyuria, determined from frequency-volume charts and defined as the production of >33% of the 24 h urine volume overnight, averaged over a 1-week period. In a double-blind study of cross-over design, a 1-week placebo run-in period was followed by two 2-week periods of placebo or 20 microg intranasal desmopressin, and ended with an open 2-week treatment period with 40 microg desmopressin.
  
  
  RESULTS
  Desmopressin caused a significant reduction in nocturnal urine volume and the percentage of urine passed at night, but the reduction in nocturnal frequency was only significant during treatment with 40 microg desmopressin. Four patients on desmopressin experienced side-effects, three of which were thought to be due to fluid retention.
  
  
  CONCLUSIONS
  Desmopressin is an effective treatment for nocturnal polyuria in some elderly men. However, it can cause fluid retention and should not be given to patients with cardiac failure. Those undergoing treatment must be closely monitored.
