Diuretic treatment of nocturnal enuresis: preliminary results of an open pilot study.
OBJECTIVE
Since antidiuretic treatment with desmopressin in the evening has proven effective against enuresis, it would not be surprising if diuretic treatment in the afternoon would have similar effects. We are currently testing this in an open pilot investigation.


METHODS
A total of 33 children including 12 girls with a mean age +/-SD of 7.6 +/- 2.3 years with monosymptomatic enuresis were recruited from an outpatient primary care setting. Wet and dry nights were recorded for 2 weeks without medication, 2 weeks with 0.4 mg desmopressin orally at night and 2 weeks with 1 mg/kg furosemide 4 to 5 hours before bedtime.


RESULTS
The mean number of wet nights +/-SD during the 3 periods was 10.2 +/- 3.0, 6.7 +/- 4.7 and 7.8 +/- 4.5, respectively. The effects of desmopressin and of furosemide were statistically significant (p <0.0001 and p = 0.001), although the 2 treatments did not differ (p = 0.08). Only 6 children had a complete response (ie greater than 90% reduction in wet nights) to desmopressin and 5 responded to furosemide. Interestingly, 2 children had a clearly better response on furosemide than on desmopressin.


CONCLUSIONS
The treatment of enuresis with diuretic medication in the afternoon may be beneficial but needs to be tested in randomized controlled trials.
