Which intervention has the best evidence for long-term success in preventing nocturnal enuresis?

• A. Sleep hygiene
• B. Desmopressin
• C. Fluid restriction
• D. Bed alarms

Answer: (D)

Bed alarms rely on conditioning the child to wake when the bladder is full, teaching arousal and voluntary voiding during sleep. This learning persists, so many children stay dry even after the alarm is stopped, giving durable long-term improvement. Trials and reviews repeatedly show higher long-term remission with alarm therapy compared to pharmacologic options or simple behavioral measures. Desmopressin can reduce wet nights quickly, but relapse after stopping is common, limiting its lasting effectiveness. Sleep hygiene and fluid restriction have only modest and less durable effects. So, bed alarms have the strongest evidence for sustained success in preventing nocturnal enuresis.
