凡治小水闭塞不通，危急之甚，诸药不效者。速寻白菊花根捣烂，用生白酒冲和，取酒
汁温而饮之，神效。按此方或白花者一时难得，即不拘何色，但以家菊根代之，亦必无不效
。一法治膀胱有溺，或因气闭，或因结滞阻塞，不能通达，诸药不效，危困将死者，用猪溲
胞一个，穿一底窍，两头俱用鹅翎筒穿透，以线扎定，并缚住下口根下出气者一头，乃将溲
胞吹满，缚住上窍，却将鹅翎尖插入马口，解去根下所缚，手捻其胞，使气从尿管透入膀胱
，气透则塞开，塞开则小水自出，大妙法也。
一、通塞法∶凡败精干血，或溺孔结垢，阻塞水道，小便胀急不能出者。令病患仰卧，
亦用鹅翎筒插入马口，乃以水银一二钱徐徐灌入，以手逐段轻轻导之，则诸塞皆通；路通而
水自出，水出则水银亦从而喷出，毫无伤碍，亦最妙法也。
一、熏洗通便法∶凡偶有气闭，小水不通，胀急危困之极者，速用皂角、葱头、王不留
行各数两，煎汤一盆，令病者，坐浸其中，熏洗小腹下体。久之，热气内达，壅塞自开，便
即通矣。若系妇人，亦可用葱数茎塞阴户中，外加熏洗，其通尤速。
易老云∶寒在胞中，遏塞不入，热在下焦，填塞不便，须用感北方寒水之化，气味俱阴
之药，以除其热，泄其闭塞。
东垣治一人，病小便不利，目睛突出，腹胀如鼓，膝以上坚硬，皮肤欲裂，饮食不下，
服甘淡渗利之药皆不效。予曰∶疾急矣，非精思不能处。思至半夜，曰∶吾得之矣！经曰膀
胱者，津液之腑，必气化而能出焉。多服渗利之药而痛益甚，是气不化也。启玄子云∶无阳
则阴无以生，无阴则阳无以化。甘淡气薄者皆阳药，独阳无阴，欲化得乎？遂以滋肾丸群阴
之剂投之，再服愈。
丹溪曰∶小便不通，有气虚，有血虚，有实热，有痰，有湿，有气结下焦。血气干者，
死。
凡是治疗小便闭塞不通，病情危急至极，各种药物都无效的情况。迅速寻找白菊花的根部捣烂，用生白酒冲调混合，取酒汁温热后饮用，效果神奇。按：这个方子如果一时找不到白花（菊花），即使不拘泥于什么颜色，只要用家菊的根代替，也一定没有不有效的。
另一种方法治疗膀胱内有尿液，或者因为气机闭塞，或者因为瘀结阻滞堵塞，导致不能通达，各种药物无效，危困快要死亡的患者，用一个猪膀胱，底部穿一个孔，两头都用鹅毛管穿透，用线扎紧固定，并绑住下面出口根部排出气体的一头，然后将猪膀胱吹满气，绑住上面开口，将鹅毛管的尖端插入尿道口，解开根部所绑的部分，用手挤压膀胱，使气体从尿管透入膀胱，气体透入则阻塞打开，阻塞打开则小便自然流出，这是非常奇妙的办法。
第一种，通塞法：凡是败精干血，或者尿道口结成垢腻，阻塞水道，小便胀急无法排出的患者。让病人仰卧，也用鹅毛管插入尿道口，然后用水银一两到二钱徐徐灌入，用手逐段轻轻引导，那么所有的阻塞都能通畅；道路通了而水自然流出，水流出来水银也随之喷出，毫无伤害妨碍，这也是最奇妙的办法。
第二种，熏洗通便法：凡是偶然出现气机闭塞，小便不通，胀急危困到了极点的情况，迅速使用皂角、葱头、王不留行各数两，煎煮一盆汤，让病人坐在其中，熏洗小腹和下体。时间久了，热气内达，壅塞自然打开，大便随即通畅。如果是女性，也可以用几根葱塞入阴道中，外加熏洗，其通畅速度尤其快。
易老说：寒邪在胞宫中，遏阻闭塞不入；热邪在下焦，填塞不便。必须使用感受北方寒水之化，气味都属于阴的药物，来清除热邪，泄去闭塞。
东垣治疗一个人，患小便不利，眼球突出，腹部胀大如鼓，膝盖以上坚硬，皮肤紧绷欲裂，饮食不下，服用甘淡渗利的药物都无效。我说：病势紧急了，不精心思考不能处方。思考到半夜，说：我找到原因了！经书说：膀胱是津液之腑，必须经过气化才能排出。多服渗利药物而疼痛更加严重，这是气不化的缘故。启玄子说：没有阳则阴无法生成，没有阴则阳无法化生。甘淡气薄的都是阳药，只有阳没有阴，想要化生怎么可能呢？于是用滋肾丸这一类纯阴的药剂投予他，再服药后痊愈。
When treating severe urinary retention where the condition is critical and all other medications have failed, quickly seek the root of the white chrysanthemum (*Chrysanthemi Flos* root), crush it into a paste, mix it with raw *Baijiu* (white liquor), take the juice, warm it, and drink it; the effect is miraculous. Note: If white chrysanthemums are hard to find in time, any color will do; simply substituting the root of common garden chrysanthemum (*Ju Hua Gen*) will also be invariably effective.
Another method for treating cases where urine is retained in the Bladder due to Qi obstruction or stagnation/blockage, rendering passage impossible, and where all medicines fail, leaving the patient in critical danger of death: Take one pig bladder, pierce a hole in its base, and pass goose quill tubes through both ends, securing them tightly with thread. Bind the lower end (the neck/root) which allows air to escape. Inflate the bladder fully, tie off the upper opening, insert the tip of the goose quill tube into the urethral meatus ("Ma Kou"), release the binding at the root, and manually squeeze the bladder. This forces air through the urethra into the bladder; once the Qi penetrates, the obstruction opens, and urine flows naturally. This is an excellent method.
First, the Method for Unblocking Obstruction: For cases where stale semen and dried blood, or calculus/debris in the urethral orifice, block the water pathway, causing distending urgency and inability to urinate: Have the patient lie supine. Insert a goose quill tube into the urethral meatus, then slowly instill 1–2 qian of mercury. Gently guide it section by section with your hand. All obstructions will clear; once the path is open, urine flows out, and the mercury is expelled along with it, causing no harm. This is also a superb method.
Second, the Method of Fumigation and Washing to Unblock Bowels/Urination: For sudden Qi closure resulting in urinary retention, with extreme distending urgency and critical distress: Quickly decoct several liang each of *Zao Jiao* (Gleditsiae Sinensis Fructus Spina), scallion heads, and *Wang Bu Liu Xing* (Vaccariae Semen) in a basin of water. Have the patient sit in it, fumigating and washing the lower abdomen and genitalia. After a while, the heat penetrates inward, the congestion opens, and urination/bowel movement becomes unblocked. For female patients, inserting several stalks of scallion into the vagina, combined with external fumigation and washing, yields even faster results.
Yi Lao stated: When cold resides in the Bao Zhong (uterus/bladder region), obstructing entry; and heat fills the Lower Jiao, causing difficulty in discharge, one must use herbs that embody the transformation of Northern Cold Water, possessing Yin natures in both flavor and aroma, to clear the heat and drain the obstruction.
Dong Yuan treated a patient suffering from difficult urination, protruding eyeballs, abdominal distension like a drum, hardness above the knees, skin tight as if about to split, and inability to eat. The patient had taken sweet and bland diuretic herbs without effect. I said: "The disease is urgent; it requires careful deliberation to prescribe." I pondered until midnight and said: "I have found the cause! The Classics state: 'The Bladder is the Mansion of Fluids; it must undergo Qi transformation to discharge.' Taking excessive diuretics worsened the pain, indicating a failure of Qi transformation. Qi Xuan Zi said: 'Without Yang, Yin cannot be generated; without Yin, Yang cannot transform.' Sweet and bland, thin-aroma herbs are Yang tonics; having only Yang without Yin, how can transformation occur?" Thus, I administered *Zi Shen Wan* (Kidney-Nourishing Pill), a formula composed entirely of Yin-nourishing agents. After two doses, the patient recovered.
Dan Xi stated: Urinary retention may be caused by Qi deficiency, Blood deficiency, Excess Heat, Phlegm, Dampness, or Qi knotting in the Lower Jiao. If Blood and Qi are exhausted, death ensues.
