Abstract
A total of 263 patients with functional enuresis were examined in this study. Their ages ranged from 4 to 22 years. Two hundred thirty-six cases (90%) belonged to the persistent type and the remaining 27 to the aquired type.Twenty-two out of 27 aquired type of patients (81%) had had the history of spontaneous awaking for micturition before enuresis began, while only 57 of 1,017 healthy children (6%) were proved to have such a habit.Twenty-four of 27 such patients (89%) were found to have experienced certain psychological or physical stresses just before the onset of their enuresis. Such stersses were likely to cause supression of their spontaneous awaking and subsequent appearance of their enuresis.Most of the patients with the persistent type of enuresis were shown to have had pollakisuria even in thier diaper period and also a tendency not to be woken up easily. A combination of these two factors, i.e. decreased urine keeping capacity and deep sleep, was thouth to cause enuresis in these patients. It was also suggested that psychological astresses increased urinary frequency and thus aggravated enuresis.
