The document provides guidelines for the practical management of enuresis. It defines enuresis as involuntary wetting during sleep by children over 5 years old without underlying medical issues. Primary enuresis involves never achieving nighttime continence, while secondary occurs after a period of being dry at night. Evaluation involves assessing the pattern of bedwetting, fluid intake, bladder diary, and psychology. Treatment is stepped, starting with general advice, alarms, and desmopressin as first-line options before considering second-line anticholinergics or third-line tricyclic antidepressants if needed. The goals are increasing dry nights and reducing the emotional impact.
3. Micturation reflexMicturation reflex
The micturition reflex is overridden by voluntary
control. Descending pathways from the cerebral
cortex can inhibit parasympathetic neurons and
stimulate motor neurons that excite the external
urethral sphincter and thus inhibit the micturition
reflex.

If primary nocturnal enuresis is not distressing to the child,
treatment is unnecessary, although parents should be reassured
about their child’s physical and emotional health and counseled
about eliminating guilt, shame, and punishment. (Grade B)

30. First line treatment
Alarm Desmopressin
an alarm is considered inappropriate, particularly if:
◆ bedwetting is very infrequent (that is, less than 1–2 wet beds per
week)
◆ the parents or carers are having emotional difficulty coping with the
burden of bedwetting
rapid-onset and/or short-term improvement in
bedwetting is the priority of treatment or
− an alarm is inappropriate or undesirable (see
recommendation
Alarm is the first line for
families who are well
motivated and well
informed
Do not exclude alarm treatment as an option for children and young
people with:
● daytime symptoms as well as bedwetting
● secondary onset bedwetting

Have the greatest chance of success in the child with signs of detrusor
overactivity, i.e. low daytime voided volumes.
Repeated courses can be used
Doses can be doubled in over 12 years children
The main side effects are dry mouth, headaches, constipation, retention
of urine and very occasionally unusual behaviour or night terrors
40. ImipramineImipramine
How Is It Given?How Is It Given?
• Start as a low dose (25 mg for children > 6 years, 50
to 75 mg for children > 11 years) and increase
fortnightly to the maximum dose allowed for the age
of the child (50 mg in children 7 to 12 years of age
and up to 75 mg in older children)
• The single daily dose should be given around 3
hours before sleep
• A course of treatment should last for 3 months
maximum before reducing the dose slowly and
stopping it for a week or so to assess progress

42. Take Home MessegeTake Home Messege
• The initial evaluation of the enuretic child should
focus on good history and with no radiology or
invasive procedures
• The first step in assessment is to exclude underlying
disorders, such as diabetes, kidney disease or
urogenital malformations
• The main goals of treatment are to increase the
number of dry night and to alleviate the emotional
impact of enuresis
43. Take Home MessegeTake Home Messege
• Positive reward systems have a better impact on the
enuretic child (Grade B)
• Bladder training, retention control training, and dry
bed training are no longer recommended
44. Take Home MessegeTake Home Messege
• Therapy is a stepwise process. Partial response is
better than no response
• The first-line treatment is the enuresis alarm or
desmopressin
• In therapy resistant cases occult constipation needs
to be ruled out
• The second line of therapy is anticholinergic
treatment combined with desmopressin
45. Take Home MessegeTake Home Messege
• In situations when all other treatments have failed,
imipramine treatment is warranted, provided the
cardiac risks are taken into account
