Nocturnal enuresis, commonly known as bedwetting, is described in documents dating from 1550 BC. Derived from the Greek word enourein, meaning "in urine" or "inability to control urination," it occurs in 15 to 20 per cent of five year olds and is twice as common in boys as girls. Indeed, no cure has yet been found and thousands of children and their families live with the distress the condition causes. Among affected children, this often includes behavioral problems and low self-esteem.
夜间遗尿症，俗称尿床，早在公元前1550年的文献中就有记载。该词源于希腊语enourein，意为“在尿液中”或“无法控制排尿”，在5岁儿童中，发病率为15%至20%，男孩的发病率是女孩的两倍。事实上，目前尚未找到治愈方法，成千上万的儿童及其家庭都饱受这种疾病带来的困扰。在受影响的儿童中，这种困扰通常包括行为问题和自卑心理。
