[Primary enuresis in children. Which treatment today?].

Nowadays enuresis is a problem that pediatric urologists are often called to treat, since it affects 15 to 30% of school-age children. In 85% of affected children bedwetting is monosymptomatic, not accompanied by other voiding disorders or daytime incontinence. Treatment of choice is still highly controversial, as the physiopathology is not yet fully understood and the pathogenesis is multifactorial: genetic and psychological factors, sleep disorders, urinary reservoir abnormalities, urine production disorders can all play a part. Behavioural treatments (psychotherapy, bladder training and biofeedback, electric alarm) and pharmacological therapy (tricyclic antidepressants, anticholinergics, DDAVP) have been used with variable results. In our 1 year experience (54 enuretic children) DDAVP proved to be effective in reducing the number of wet nights per week in 79% of cases. Acupuncture, which we have been using for many years, also gave good results in 55% of treated patients. Long term success of DDAVP and acupuncture was respectively 50 and 40%. We discuss the probable pathophysiology and present our own results and those reported in the literature. It has to be stressed that an accurate diagnostic selection of patients and a better understanding of physiopathology are the basis of effective treatment of enuresis.
