秦子曰∶小便不通，非一例也。在外感五运中，则有运气加临，伤寒门，则有热结膀胱
，混热发黄，汗下亡津。阴症中，则有寒湿内结。内伤门，则有肺热，心热，肾热，水液
偏渗，气化不及，真阴不足诸症，今立外感三条，内伤五条，虽或未尽治法，然亦可以为准绳
【运气小便不利之症】阳明司政，躁热加临，发热烦渴，小便不利，少阴司政。君火
行令，发热舌赤，小便不利。太阴在泉，不得小便，病癃闭。厥阴司天。大便泻，小便闭，此
运气小便不利之症也。
【运气小便不利之因】《内经》云∶阳明司天，天气急，地气明，则民病癃闭。少阴司
天，地气肃，天气明，则病淋闭。太阴在泉，湿淫所胜，则小便不利，不及则亦病癃闭。厥阴
司天，风湿所胜，风邪入土，水谷偏走大肠，则病溏泄水闭。凡此运气加临，则小便不利矣
【运气小便不利之脉】右脉数大。阳明燥热，左脉数大。少阴之别，右脉濡缓，太阴湿
淫，左脉浮弦，厥阴风邪。
【运气小便不利之治】阳明燥热，知母石膏汤、清燥汤。少阴君火，导赤各半汤。太阴
湿胜，苍术防风汤。水不及，清燥汤。厥阴风湿，防风汤。水谷偏渗大肠，防风四苓散。

秦子说：小便不通，并非只有一种情况。在外感病与五运六气的变化中，存在运气加临的影响；在伤寒门类中，则有热邪结于膀胱、湿热混杂导致发黄、以及发汗或攻下后津液耗伤等情况。在阴证门类中，则有寒湿内结的情况。在内伤门类中，则有肺热、心热、肾热、水液偏渗（水液异常流向大肠）、气化功能不及、真阴不足等多种症状。如今设立外感三条、内伤五条的论述，虽然或许未能涵盖所有治法，但也可以作为准则。
【运气所致小便不利的症状】当阳明燥金主政时，躁热之气加临人体，会出现发热、烦躁口渴、小便不利；少阴君火主政时，君火行使令权，会出现发热、舌质红赤、小便不利；太阴湿土在泉时，会出现无法排尿，病症表现为癃闭（小便点滴而出或完全不通）；厥阴风木司天时，会出现大便泄泻、小便闭塞，这些是运气因素导致的小便不利症状。
【运气所致小便不利的病因】《内经》记载：阳明司天时，天气急迫，地气明朗，民众易患癃闭之症；少阴司天时，地气肃杀，天气明朗，易患淋证和闭证；太阴在泉时，若湿气过胜，则小便不利；若湿气不及，也会患癃闭之症；厥阴司天时，风湿之气过胜，风邪侵入脾土，导致水谷精微偏走大肠，从而出现溏泄和水液闭塞的症状。凡是这种运气加临的情况，都会导致小便不利。
【运气所致小便不利的脉象】右侧脉象数而大，属阳明燥热；左侧脉象数而大，属少阴之别脉；右侧脉象濡缓，属太阴湿淫；左侧脉象浮弦，属厥阴风邪。
【运气所致小便不利的治法】针对阳明燥热，使用知母石膏汤、清燥汤；针对少阴君火，使用导赤各半汤；针对太阴湿胜，使用苍术防风汤；针对湿气不及，使用清燥汤；针对厥阴风湿，使用防风汤；针对水谷偏渗大肠，使用防风四苓散。

Qin Zi said: Obstruction of urination is not a single condition. In the context of external contraction and the changes of the Five Movements (Wu Yun), there are influences from the superimposition of Qi movements (Yun Qi Jia Lin). In the category of Cold Damage (Shang Han), there are cases of heat binding in the Bladder, yellowing caused by mixed damp-heat, and loss of body fluids due to sweating or purging. In the category of Yin syndromes, there is internal binding of cold-dampness. In the category of internal injury, there are symptoms such as Lung heat, Heart heat, Kidney heat, abnormal leakage of fluids (Shui Pian Shen), failure of Qi transformation (Qi Hua Bu Ji), and deficiency of True Yin. Currently, three categories for external contraction and five categories for internal injury are established. Although they may not exhaust all treatment methods, they can serve as a standard.
[Symptoms of Urinary Difficulty Caused by Qi Movements] When Yangming governs, dry-heat superimposes, causing fever, irritability, thirst, and difficulty in urination. When Shaoyin governs, Minister Fire exercises its command, causing fever, red tongue, and difficulty in urination. When Taiyin is in the lower position (Zai Quan), inability to urinate occurs, manifesting as Long-Bi (strangury with obstruction). When Jueyin governs from above (Si Tian), diarrhea occurs alongside urinary closure. These are symptoms of urinary difficulty caused by Qi movements.
[Etiology of Urinary Difficulty Caused by Qi Movements] The *Neijing* states: When Yangming governs from above, the heavenly Qi is urgent and the earthly Qi is bright, people suffer from Long-Bi. When Shaoyin governs from above, the earthly Qi is solemn and the heavenly Qi is bright, people suffer from Lin syndrome and Bi syndrome. When Taiyin is in the lower position, if dampness overcomes, urination becomes difficult; if it is insufficient, Long-Bi also occurs. When Jueyin governs from above, if wind-dampness overcomes, wind pathogen enters the Earth element (Spleen/Stomach), causing water and grain to deviate to the Large Intestine, resulting in loose stools and water closure. All these superimpositions of Qi movements lead to difficulty in urination.
[Pulse Patterns of Urinary Difficulty Caused by Qi Movements] A rapid and large pulse on the right indicates Yangming dry-heat. A rapid and large pulse on the left indicates the branch pulse of Shaoyin. A soggy and slow pulse on the right indicates Taiyin dampness invasion. A floating and wiry pulse on the left indicates Jueyin wind pathogen.
[Treatment of Urinary Difficulty Caused by Qi Movements] For Yangming dry-heat, use Zhimu Shigao Tang (Anemarrhena and Gypsum Decoction) and Qingzao Tang (Clear Dryness Decoction). For Shaoyin Minister Fire, use Daochi Geban Tang (Half-Combination Decoction for Guiding Out Redness). For Taiyin dampness excess, use Cangzhu Fangfeng Tang (Atractylodes and Saposhnikovia Decoction). For insufficiency of moisture, use Qingzao Tang. For Jueyin wind-dampness, use Fangfeng Tang. For water and grain deviating to the Large Intestine, use Fangfeng Siling San (Saposhnikovia and Four-Poria Powder).
