经曰∶膀胱者，州都之官，津液藏焉，气化则能出矣。又曰∶膀胱不利为癃，不约为遗溺。又曰∶肝有热则
小便先赤。凡小便赤涩为热，小便自遗为寒。热者火有余，水不足，治宜泻心火、滋肾水，加味导赤散；寒者火
不足，水有余，治宜温肾水、益心火，益智散。
小便不通，乃由脏气虚，受热壅滞，宣化不行，非塞非痛，但闭而不通，腹胀紧满。宜五苓散加车前、灯芯。
大病之后，气虚津液不足，而小便闭者，不可利之。利则中气日虚，津液愈涸。宜人参散。
小儿患淋，小便淋沥作痛，不必分五种，然皆属火热。宜清利之，海金砂散。
小儿久病气虚而淋病者，不可利小便，宜六味地黄丸，滋其化源。
小便自出而不禁者，谓之遗尿；睡中自出者，谓之尿床。此皆肾与膀胱虚寒也。益智散加附、桂、龙骨。
小儿初便黄赤，落地良久，凝如白膏者，谓之尿白。伤脾所致，久而成疳。胃苓丸，盐
汤下。
小儿小便出时，色白混浊，随尿而来，谓之白浊。此心经虚热，宜清心莲子饮。

The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: The Bladder is the official of the "State Capital" (Zhou Du), responsible for storing body fluids (Jinye); it can discharge them only through Qi transformation. It also states: When the Bladder's Qi mechanism is obstructed, it leads to Long Bi (urinary retention/incomplete voiding); when its constraining function is deficient, it leads to Yi Niao (urinary incontinence). Furthermore, it states: When there is heat in the Liver, the urine will first become red and dark. Generally, urine that is red and scanty with dysuria indicates Heat; spontaneous urinary incontinence indicates Cold. Heat patterns involve excess Heart Fire and deficient Kidney Water; treatment should focus on purging Heart Fire and nourishing Kidney Water, using Jiawei Daochi San (Modified Guide Out Red Decoction). Cold patterns involve deficient Heart Fire and excess Kidney Water; treatment should focus on warming Kidney Water and benefiting Heart Fire, using Yizhi San (Yi Zhi Pill).
Urinary obstruction arises from deficiency of Zang-Fu Qi combined with stagnation due to Heat pathogens, leading to failure of diffusion and Qi transformation. It is not caused by physical blockage or pain, but by closure without passage, accompanied by abdominal distension and tightness. Wuling San (Five-Ingredient Powder with Poria) added with Cheqianzi (Plantago Seed) and Dengxincao (Juncus Effusus) is appropriate.
After a severe illness, if urinary obstruction occurs due to Qi deficiency and insufficient body fluids, diuretics must not be used. Using diuretics will further deplete Middle Jiao Qi and dry up body fluids. Renshen San (Ginseng Decoction) is appropriate.
When children suffer from Lin Syndrome (strangury), characterized by dribbling and painful urination, it is unnecessary to distinguish among the five types of Lin; all belong to Fire-Heat. Clearing Heat and promoting urination is appropriate, using Haijinsha San (Hai Jin Sha Powder).
For children suffering from Lin Syndrome due to Qi deficiency after prolonged illness, diuretics should not be used. Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) is appropriate to nourish the source of transformation.
Spontaneous leakage of urine without control is called Yi Niao (enuresis/urinary incontinence); involuntary urination during sleep is called Niao Chuang (bedwetting). These are both caused by deficiency-cold of the Kidney and Bladder. Yizhi San (Yi Zhi Pill) added with Fuzi (Aconite Lateral Root), Rougui (Cinnamon Bark), and Longgu (Fossilized Bones) is appropriate.
If a child's initial urine is yellow and red, and after remaining on the ground for some time, coagulates into a white paste-like substance, it is called Niao Bai (white urine). This is caused by Spleen injury and may develop into Gan Accumulation (pediatric malnutrition syndrome) over time. Weiling Wan (Wei Ling Pill) taken with salt water is appropriate.
If a child's urine is white and turbid upon discharge, coming along with the stream, it is called Bai Zhuo (white turbidity). This is caused by deficiency-heat in the Heart Meridian. Qingxin Lianzi Yin (Clear Heart Lotus Seed Decoction) is appropriate.
