Abstract

Bedwetting is the involuntary elimination of urine at night, after a complete urinary voiding in individuals with five or more years of age. Nocturnal Enuresis (NE) can be either monosymptomatic (MNE), when it occurs in the absence of other symptoms, or polysymptomatic (PNE) in the presence of symptoms such as daytime and nocturnal urinary loss, urinary tract infection and / or encopresis. EN is called primary when involuntary urinary loss was never controlled, and secondary, when there has been adequate prior sphincteric control for at least six months.NE is a mismatch between the amount of urine produced at night and the functional capacity of the bladder, in a patient in whom the stimulus of a full bladder is not capable of producing sleep arousal. MNE can be characterized as a multifactorial disease expressed predominantly as nocturnal polyuria or as a functional reduction of bladder capacity The possible causes of nocturnal polyuria are missing/inadequate nocturnal peak of antidiuretic hormone, increased nocturnal urinary excretion of solute and possibly other factors such as sleep apnea, hypercalciuria and aquaporin 2 dysfunction. Polysomnography studies show bladder filling and bladder emptying predominantly during deep.Brazilian studies on management of MNE, are very scarce. In the present study, participants with MNE and nocturnal polyuria will be included after informed consent, this selection criteria will eliminate the bias of most previous studies in which patients with low functional bladder capacity and nocturnal polyuria were evaluated in the same treatment group, without taking into account the pathophysiological aspects of these two differing forms of ENM when choosing therapy,. Previously to intervention, the participants will be evaluated in terms of postural health, mental status and polysomnography to study the sleep pattern and to exclude cases of obstructive sleep apnea related enuresis. The study protocol consists of three parallel groups of patients, constituted of 20 patients randomly each, who will undergo intervention with desmopressin (DDAVP), bed alarm or both for 6 months, followed by 6 months of further observation, which will enable the evaluation of the therapeutic efficiency/frequency of relapse of each one of the interventions Polysomnography will be repeated at the end of the treatment period to evaluate intervention related changes in the sleep pattern.
