Guided by the theory of "

and

yin

being affected by damp

qi

" from

The Inner Canon of Yellow Emperor

（《黄帝内经》）， and combined with the physiological characteristic of children that the lung， spleen and kidney are often insufficient， this paper believed that the pathogenesis of pediatric enuresis is the dysfunction of the lung， spleen and kidney caused by disturbance of wind pathogen and retention of damp pathogen， which further leads to the incontinence of the bladder. Thus， the therapeutic principle of dispelling wind and resolving dampness was proposed. In clinic， pediatric enuresis can be divided into three syndromes， including wind stirring in taiyang meridian， accumulation of damp-heat， and deficiency of both spleen and kidney. Corresponding treatments are adopted respectively as following， modified

Mahuang Fuzi Xixin Decoction

（麻黄附子细辛汤） combined with

Suoquan Pill

（缩泉丸） to diffuse lung and dispel wind， warm the kidney and stop enuresis； modified

Simiao Powder

（四妙散） combined with

Daochi Powder

（导赤散） to clear heat， resolve dampness， and invigorate the spleen； modified

Buzhong Yiqi Decoction

（补中益气汤） combined with

Shuilu Erxian Pill

（水陆二仙丹） to invigorate the spleen， tonify the kidney， drain dampness and stop enuresis. Meanwhile， the auxiliary application of external treatment methods is emphasized.
