The alarm is continued until there have been 14 consecutive dry nights. At this point, some authors recommend an 'overlearning'. This overlearning is continued until the patient has achieved seven dry nights in a row. If a relapse occurs, the treatment may be repeated with a success rate similar to the initial course of therapy. Because they tend to 'wear out' after two to three patients, it is most practical for parents to purchase a new alarm for their child.
Commercial companies advertise systems at a very high cost.
The public should be forewarned before purchasing these services. See Table 1 for suggested alarm systems. The enuretic children had an altered pattern of ADH secretion compared with control patients. The control patients had an elevation of ADH levels at night while the enuretic children had a constant level of ADH throughout a 24 h period. Therefore, it appears that in some children with nocturnal enuresis, high volumes of urine are produced at night with subsequent overflow of the bladder.
