Comparison of desmopressin and enuresis alarm for nocturnal enuresis
Insights
The enuresis alarm showed a higher improvement rate for nocturnal enuresis than desmopressin (DDAVP). However, desmopressin offers a rapid effect and is a useful alternative when conditioning treatment fails.
Area of Science:
- Pediatric Nephrology
- Urology
- Sleep Medicine
Background:
- Primary nocturnal enuresis affects a significant number of children.
- Current treatments include behavioral interventions like enuresis alarms and pharmacotherapy such as desmopressin (DDAVP).
Purpose of the Study:
- To compare the efficacy and safety of desmopressin (DDAVP) versus enuresis alarm in treating primary nocturnal enuresis.
- To evaluate long-term treatment effectiveness and relapse rates.
Main Methods:
- Randomized controlled trial involving 50 children with primary nocturnal enuresis.
- Participants were treated with either 20 micrograms intranasal desmopressin or an enuresis alarm for three months.
- Cross-over design for treatment failures and continued treatment for relapses over an additional three months.
Main Results:
- Improvement rates were 70% for desmopressin and 86% for the enuresis alarm, with no statistically significant difference.
- Desmopressin group showed significantly drier nights during the first week of treatment.
- Higher relapse rate observed in the desmopressin group (10 patients) compared to the alarm group (1 patient).
Conclusions:
- Enuresis alarm (conditioning treatment) is preferable for long-term management of nocturnal enuresis.
- Desmopressin (DDAVP) is a valuable alternative for rapid effect or when conditioning treatment is unsuccessful.
- No serious adverse effects were reported for either treatment modality.
Abstract:
Fifty children with primary nocturnal enuresis were randomised for a study comparing desmopressin (DDAVP) and enuresis alarm. Forty six completed the trial, 24 of whom were treated with 20 micrograms intranasal desmopressin nightly and 22 with enuresis alarm for three months. Failures were crossed over and relapses were continued on the same treatment for a further three months. The improvement rate was 70% in the group given desmopressin and 86% in the group treated with alarm; the difference was not significant. During the first week of treatment the group given desmopressin was significantly dryer, and at the end of the study 10 of these patients relapsed compared with one patient in the group given the alarm. No serious side effects were observed. This study confirms the role of conditioning treatment as preferable in long term treatment of nocturnal enuresis. When this fails or when a safe drug with rapid effect is needed, however, desmopressin is a useful alternative.

The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
