title: The relationship between desmopressin treatment and voiding pattern in children.
abstract: OBJECTIVE
  To collect data on voiding patterns at baseline (no treatment) and during short-term desmopressin treatment, with special reference to the functional and the mean bladder capacity.
  
  
  METHODS
  The study included 120 children (aged 6-16 years) with monosymptomatic nocturnal enuresis. While at home they recorded their fluid intake and diuresis in two separate periods, i.e. 2 weeks as a baseline registration and another 2 weeks during desmopressin titration. On four study days the children recorded the time and volume of all voids and of fluid intake. From the diaries their functional and mean bladder capacities, 24-h diuresis and day/night ratio of diuresis were determined.
  
  
  RESULTS
  The mean 24-h diuresis was significantly lower during short-term desmopressin treatment. In most of the enuretics the mean day/night ratio increased on desmopressin treatment. The mean functional and mean bladder capacities were unaffected by desmopressin. Those not responding had bladder capacities of approximately 100 mL less than full responders. Regardless of response, practically all the enuretics in the study had a smaller functional bladder capacity than expected for their age. Among responders the morning void was significantly larger than the following voids during the day, and among non-responders the fourth void was significantly larger than the previous voids in the day. Desmopressin treatment did not influence these volumes significantly.
  
  
  CONCLUSIONS
  Short-term desmopressin treatment does not affect functional and mean bladder capacity; 24-h urine production was reduced significantly (P<0.01) during desmopressin treatment.
