凡小儿有病，或热腹痛，或惊，大小便不通者，此症极危，
看虚实，急通利之。
如小儿形实热甚，内服三黄丸，外用贴脐法，即通。
如小儿形怯，不可下者，用熨脐法、胆导法，即通。
如用上法不通，又加腹胀气喘，多哭，闷乱，目上视，手足
冷者。不可治也。
凡小便不通者，有阴阳二症。阴闭者，冷湿乘虚入里，因而
不通，五苓散加南木香为末，空心盐汤调服。外用炒盐熨脐即
通。阳闭者，因暴热所逼，涩而不通。轻者，五苓散加前子。
灯心治之。重者，以木通散，外用熨脐法即通。
小便淋涩者，盖小肠为受盛之腑，气通于膀胱，膀胱者，为津
液之府。气通于肾，小肠受气，客于膀胱，销烁肾水，水道涩而
不利，故小便涩痛也。先以八正散泄去其热，次以香芎丸调之。
不论五淋，治法皆同。
小便出血者，热之极也。盖心生血，于小肠相合，热甚则失
其常道，故不流渗入于胞，故小便血出也。以导赤散。加蒲黄
未，空心时，灯心汤送下。
小便出白者。初出微赤，良久澄白，如米泔状。此由乳哺失
节，有伤于脾，致令清浊不分而色白也。久则成疳，以分清饮主
之。
祖传治小便：白色如米泔者，以胃苓丸温盐汤下。
小便不禁，此肾与膀胱俱虚，而冷气乘之，故不能制其尿出
而不禁，谓之遗尿。睡里自出者，谓之尿床。俱以鸡肠散治，更
以地黄丸调之。
凡大小便不通者，有虚有热。虚者，津液不足，大肠干涩而
秘结，内服通幽汤，甚者，用导法。
热着，脏腑积热，内有燥粪。其腹必痛，或作渴，内服三黄
丸，外用导法。
大便下血者，是大肠中有积热也。因恣食酒面，炙博热物，
流入心肺二经(32)，血热妄行，渗入肠中，故大便下血。久则脏
毒，无时下血。黄连丸主之。
凡小儿初生七日之内，大小便有血者，此胎毒也。不可用他
药，只以生地黄取自然汁，入蜜少许和匀，温服之，自愈。
凡小儿非月内大小便有血者，此积热在心肺二经。热积于心，
故小便出血，热积于肺 ，故大肠出血。三黄解毒汤主之。
若小儿出痘疹之时，大小便出血者，此热毒内攻，脏腑俱
坏，乃危症也。难救。
凡小儿常时粪后出血不止者，此名野鸡痢，地榆丸主之。
凡是小儿患病，出现热性腹痛、惊风，或者大小便不通的情况，这种病症极其危险，需要辨别虚实，紧急采用通利的方法治疗。
如果小儿体质壮实且热象严重，内服三黄丸，外用贴脐法，大便即可通畅。
如果小儿体质虚弱怯弱，不能使用泻下法的，采用熨脐法、胆导法（用胆汁灌肠），大便即可通畅。
如果使用上述方法仍不通畅，又加上腹胀气喘、多哭、烦躁闷乱、眼睛上视、手足冰冷的症状，则属于不可治愈的危症。
凡是小便不通的，有阴闭和阳闭两种证型。阴闭是由于冷湿之邪乘虚侵入体内，导致小便不通，可用五苓散加南木香研成细末，空腹时用盐汤调服。外用炒热的盐熨烫肚脐，小便即可通畅。阳闭是由于暴热逼迫所致，小便涩滞不通。轻症用五苓散加车前子，以灯心草煎汤治疗。重症用木通散，外用熨脐法，小便即可通畅。
小便淋沥涩痛的症状，是因为小肠是受盛食物的腑，其气与膀胱相通；膀胱是津液汇聚的府，其气与肾相通。小肠受热邪侵袭，客于膀胱，灼烧肾水，导致水道涩滞而不通利，所以出现小便涩痛。先用八正散清除热邪，再用香芎丸调理。无论哪种类型的淋证，治疗方法都相同。
小便出血，是热邪极盛的表现。因为心主血，与小肠相表里，热邪极盛时违背了正常的生理规律，血液不循常道而渗入膀胱（胞），所以从小便中出血。使用导赤散，加入蒲黄粉末，空腹时用灯心草汤送服。
小便排出白色浑浊液体，初出时微红，放置良久后澄清变白，像淘米水一样。这是由于哺乳喂养不当，损伤了脾胃，导致清浊不分而颜色发白。时间久了会发展成疳积，主要使用分清饮治疗。
家传治疗小便白色的方法：如果是白色如米泔状的，用胃苓丸配合温盐水送服。
小便不禁（遗尿），这是肾与膀胱都虚弱，冷气乘虚而入，所以不能控制尿液排出，称为遗尿。睡觉时自己尿床的，称为尿床。都用鸡肠散治疗，再用地黄丸调理。
凡是大小便不通的，有虚证和热证之分。虚证是因为津液不足，大肠干燥涩滞而秘结，内服通幽汤，严重的，采用导法（灌肠或塞肛）。
热证，是因为脏腑积热，体内有燥屎。腹部必然疼痛，或者口渴，内服三黄丸，外用导法。
大便下血，是大肠中有积热。因为恣意食用酒、面食以及炙烤的热物，热邪流入心肺二经，血热妄行，渗入肠道，所以大便下血。日久会变成脏毒，不时下血。主要使用黄连丸治疗。
凡是小儿出生七天之内，大小便有血的，这是胎毒。不可以用其他药物，只用生地黄取自然汁，加入少许蜂蜜调和，温服，自愈。
凡是小儿非一个月内（满月后）大小便有血的，这是积热在心肺二经。热邪积聚在心，所以小便出血；热邪积聚在肺，所以大肠出血。主要使用三黄解毒汤治疗。
In cases where infants and children are ill, presenting with heat-induced abdominal pain, fright (Jing), or obstruction of both urination and defecation, the condition is extremely critical. One must differentiate between deficiency and excess, and urgently employ methods to promote unblocking and purgation.
If the child has a robust constitution with severe internal heat, administer Sanhuang Wan (Three-Yellow Pill) internally, and apply the navel-pasting method externally; defecation will then be facilitated.
If the child has a frail constitution and cannot tolerate purgatives, use the navel-moxibustion/warming method (Yun Qi Fa) or bile enema (Dan Dao Fa); defecation will then be facilitated.
If these methods fail to relieve the obstruction, and symptoms such as abdominal distension, panting, excessive crying, restlessness, upward deviation of the eyes, and cold extremities appear, the condition is incurable.
Regarding urinary obstruction, there are two types: Yin obstruction and Yang obstruction. Yin obstruction occurs when cold-dampness invades the interior due to deficiency, causing blockage. This can be treated by taking Nanmuxiang (Aquilaria Agallocha Wood) powder mixed with Wuling San (Five-Ingredient Poria Decoction), administered on an empty stomach with salt water. Externally, applying hot roasted salt to the navel will facilitate urination. Yang obstruction is caused by sudden intense heat forcing fluids, resulting in scanty and difficult urination. For mild cases, treat with Wuling San (Five-Ingredient Poria Decoction) added with Cheqianzi (Plantago Seed), using Dengxincao (Juncus Effusus) decoction. For severe cases, use Mutong San (Akebia Decoction) and apply the navel-warming method externally to facilitate urination.
The symptom of dribbling and painful urination (Lin syndrome) arises because the Small Intestine is the fu-organ responsible for receiving and containing, its qi connecting with the Bladder. The Bladder is the storage organ for body fluids, its qi connecting with the Kidney. When pathogenic heat enters the Small Intestine and affects the Bladder, it consumes Kidney yin/fluids, causing the water passages to become obstructed and ineffective, thus leading to painful and difficult urination. First, clear the heat using Bazheng San (Eight-Herb Corrective Decoction), then regulate with Xiangxiong Wan. The treatment principle remains the same regardless of the specific type of Lin syndrome.
Hematuria indicates extreme heat. Since the Heart governs blood and corresponds to the Small Intestine, excessive heat causes blood to deviate from its normal course and渗 (seep) into the Bladder (Pao), resulting in blood in the urine. Treat with Daochi San (Guide Out Redness Decoction) added with Puhuang (Typha Pollen), taken on an empty stomach with Dengxincao (Juncus Effusus) decoction.
White turbid urine, which appears slightly red initially but becomes clear and white like rice wash water after standing, results from improper breastfeeding or feeding damaging the Spleen, leading to a failure in separating the clear from the turbid. If prolonged, this may develop into Gan disease (malnutrition/infantile malaise). Treat primarily with Fenqing Yin (Separate Clear Decoction).
Ancestral prescription for white urine: For urine resembling rice wash water, administer Weiling Wan (Gastrodia and Atractylodes Pill) with warm salt water.
Urinary incontinence occurs when both the Kidney and Bladder are deficient, allowing cold qi to invade, resulting in an inability to control urine release, termed Yi Niao (bedwetting/enuresis). Nocturnal enuresis is specifically called Niao Chuang. Treat both with Jichang San (Chicken Gizzard Lining Decoction), followed by regulation with Dihuang Wan (Rehmannia Pill).
Obstruction of both urination and defecation can stem from deficiency or heat. Deficiency involves insufficient body fluids, leading to dryness and constipation in the Large Intestine. Administer Tongyou Tang (Unblock the Abyss Decoction) internally; for severe cases, use enema methods. Heat patterns involve accumulated heat in the zang-fu organs and dry feces within. Abdominal pain and thirst are likely present. Administer Sanhuang Wan (Three-Yellow Pill) internally and use enema methods externally.
Blood in the stool indicates accumulated heat in the Large Intestine. This results from indulging in alcohol, wheat products, and roasted/hot foods, causing heat to flow into the Heart and Lung meridians. Blood heat forces reckless movement, seeping into the intestines, causing hematochezia. If chronic, it may become Zang Du (visceral toxin) with intermittent bleeding. Treat primarily with Huanglian Wan (Coptis Pill).
For infants within seven days of birth, blood in urine or stool indicates Tai Du (fetal toxin). Do not use other medicines; instead, extract fresh juice from Sheng Dihuang (Raw Rehmannia Root), mix with a little honey, and administer warm; it will heal spontaneously.
For infants beyond the first month, blood in urine or stool indicates accumulated heat in the Heart and Lung meridians. Heat accumulating in the Heart causes hematuria; heat accumulating in the Lung causes hematochezia. Treat primarily with Sanhuang Jiedu Tang (Three-Yellow Detoxifying Decoction).
If an infant experiences blood in urine or stool during the eruption of chickenpox/smallpox, this indicates internal attack by heat-toxin, destruction of the zang-fu organs, representing a critical and difficult-to-save condition.
For infants who experience persistent bleeding after defecation regularly, this is named Ye Ji Li (Wild Pheasant Dysentery). Treat primarily with Diyue Wan (Sanguisorba Pill).
