Insights
Enuresis alarm systems significantly increase bladder storage capacity in children. This 12-week treatment improves maximum functional, daytime, and nocturnal bladder capacities, aiding in nighttime dryness.
Area of Science:
- Pediatric urology
- Sleep medicine
- Behavioral therapy
Background:
- Enuresis alarm systems are used to treat nocturnal enuresis, but their mechanism of action is not fully understood.
- These alarms help children wake before voiding and eventually sleep through the night dry.
Purpose of the Study:
- To investigate the effect of enuresis alarms on bladder storage capacities in children with nocturnal enuresis.
Main Methods:
- 28 children over 7 years old, not polyuric, with nocturnal enuresis, were enrolled.
- Patients used frequency/volume charts pre- and post-12 weeks of bell-and-pad alarm treatment.
- Physical and laboratory examinations were conducted prior to treatment.
Main Results:
- Maximum functional bladder capacity increased from 178.35 ml to 243.03 ml (p < 0.0001).
- Mean daytime bladder capacity increased from 111.11 ml to 148.45 ml (p < 0.0001).
- Maximum nocturnal bladder capacity increased significantly from 177.85 ml to 255.25 ml (p < 0.0001).
Conclusions:
- 12-week enuresis alarm treatment significantly increases bladder storage capacities.
- The study demonstrates improvements in maximum nocturnal, functional, and daytime bladder capacities.
- Alarm systems are effective in enhancing bladder storage for enuresis management.
Objective:
Despite a great number of studies, very little is known about the mechanism of action of enuresis alarm systems. Nevertheless, as a result of this treatment many children are able firstly to wake up before urination occurs and then, in time, to sleep through the night without voiding. The aim of this study was to investigate the effect of enuresis alarms on bladder storage capacities.
Material And Methods:
A total of 28 children aged >7 years who were not polyuric but who voided once every night, slept alone in their own bedroom and who were willing, along with their family members, to cooperate were recruited. Patients were asked to record their urine output using a frequency/volume chart for two consecutive days. After these records and the results of physical and laboratory examinations were taken into consideration, treatment was instituted with the bell-and-pad (alarm) system for a period of 12 weeks. At the end of this period, patients were asked to complete another frequency/volume chart.
Results:
The pre- and post-treatment maximum functional bladder capacity was 178.35 +/- 87.86 ml and 243.03 +/- 102.84 ml, respectively and the pre- and post-treatment mean day-time bladder capacity was 111.11 +/- 45.87 and 148.445 +/- 7.68 ml. Both of these differences were statistically significant (p < 0.0001 and <0.0001, respectively). The maximum nocturnal bladder capacity was found to be increased from 177.85 +/- 84.95 to 255.25 +/- 124.52 ml after treatment (p < 0.0001).
Conclusion:
Treatment with the alarm system for a period of 12 weeks was seen to be associated with a significant increase in bladder storage capacities (maximum nocturnal bladder capacity, maximum functional bladder capacity and mean day-time bladder capacity).

01:26The 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...
