Diurnal enuresis in childhood.
OBJECTIVE
To review the clinical classification of childhood diurnal enuresis, to describe the evaluation process, and to discuss principles of management.


METHODS
An extensive literature review was performed with a MEDLINE search. Articles were selected according to date of publication, clinical relevance, and availability. Recent articles, cohort studies of at least 50 patients, and randomized clinical trials were preferred. Recent editions of classic textbooks were consulted. Evaluation and management activities discussed in this article are supported by original and relevant literature.


RESULTS
Most causes of childhood diurnal enuresis can be determined by a thorough history coupled with a complete physical examination and urinalysis and culture. Supplementary investigations include ultrasonography of the kidneys and bladder to screen for neurogenic bladder and urethral obstruction. When obstruction, ectopic ureter, or bladder dysfunction is suspected, voiding cystourethrography and urodynamic studies are needed. Evaluation of neurogenic bladder includes magnetic resonance imaging of the spine. Treatment is aimed at correcting poor toilet habits, preventing or treating urinary tract infections, and using appropriate medication.


CONCLUSIONS
In most instances, diurnal enuresis in childhood is a benign condition with an easily identifiable cause and an excellent prognosis with time and appropriate treatment.
