胞转者，由是胞屈辟，小便不通，名为胞转。其病状∶齐下急痛，小便不通是也。此病
或由小便应下，便强忍之，或为寒热所迫。此二者，俱令水气还迫于胞，使胞屈辟不得充张
，外水应入不得入，内溲应出不得出，外内相壅塞，故令不通。此病至四五日，乃有致死者
。饱食、食讫，应小便而忍之，或饱食讫而走马，或小便急因疾走，或忍尿入房，亦皆令胞
转，或胞落，并致死。
大便难者，由五脏不调，阴阳偏有虚实，谓三焦不和，则冷热并结故也。
胃为水谷之海
，水谷之精，化为荣卫，其糟粕行之于大肠以出也。五脏三焦既不调和，冷热壅涩，结在肠
胃之间。其肠胃本实，而又为冷热之气所并，结聚不宣，故令大便难也。
又云∶邪在肾，亦令大便难。所以尔者，肾脏受邪，虚而不能制小便，则小便利，津液
枯燥，肠胃干涩，故大便难。
又，渴利之家，大便也难，所以尔者，为津液枯竭，致令肠胃干燥。

胞转，是由于膀胱受压扭曲，导致小便不通畅，这种病症称为胞转。其症状表现为：脐下部位拘急疼痛，小便无法排出。此病有的因为应当排尿时强行憋忍，有的因为受到寒热邪气的逼迫。这两种情况，都会导致水气反迫于膀胱，使膀胱受压扭曲而不能充盈扩张，外部的水液应进入却进不去，内部的尿液应排出却排不出，内外相互壅塞阻滞，所以导致小便不通。此病如果发展到四五日，甚至会导致死亡。饱食之后，应当排尿却强行憋忍；或者饱食后立即骑马奔跑；或者尿急时快速行走；或者憋尿后行房事，这些也都可能导致胞转，或者膀胱下垂，并致死。
大便难，是因为五脏功能不调和，阴阳偏盛偏虚，即三焦功能不和，导致冷气和热气互相结聚的缘故。
胃是容纳水谷的器官，水谷中的精微物质，转化为营气和卫气，其糟粕则传导至大肠排出。五脏和三焦既然不调和，冷热之气壅滞涩结，积聚在肠胃之间。肠胃本身充实，又受到冷热之气的侵扰，结聚而不能宣通，所以导致大便困难。
又说：邪气在肾脏，也会导致大便困难。之所以这样，是因为肾脏受邪，虚弱而不能制约小便，导致小便频多，津液枯竭干燥，肠胃干涩，所以大便困难。
另外，患有消渴病（多饮多尿）的人，大便也困难，之所以这样，是因为津液枯竭，导致肠胃干燥。
诊察左手寸口人迎穴之前的脉象，属于手少阴心经。脉象沉为阴，阴实者，病症痛苦在于闭塞，大便不利，腹部胀满，四肢沉重，身体发热且胃部胀满不适。右手关上脉象阴实者，是脾实，痛苦在于肠中感觉伏伏如牢状坚硬，大便困难。脉象紧而滑，跗阳脉微弦，按法应当出现腹部胀满，如果不胀满，必定是大便困难且脚痛，这是虚寒之邪从上向下传变所致。关于汤药、熨贴、针刺、砭石的治疗方法，另有专门的方剂，补养和导引的方法，现在附在后面。
《养生方·导引法》说：仰卧，伸直双手，捻揉左右胁部。可以消除大便困难、腹痛、腹中寒气。口吸气，鼻呼气，将温热的之气吞咽下去数十次，疾病痊愈。
Baozhuan (Bladder Displacement) is caused by the compression and twisting of the bladder, resulting in the inability to urinate; this condition is named Baozhuan. Its clinical manifestations include: urgent pain below the umbilicus and urinary retention. This disease may occur due to forcibly holding urine when one should void, or due to being compelled by cold-heat pathogens. Both scenarios cause water qi to press back against the bladder, preventing it from filling and expanding normally. External fluids cannot enter, and internal urine cannot exit, leading to mutual obstruction inside and outside, thus causing blockage. If this condition persists for four to five days, it may lead to death. Eating until full and then forcibly holding urine, or running on horseback immediately after a full meal, or walking rapidly when the urge to urinate is strong, or engaging in sexual intercourse while holding urine, can all cause Baozhuan or prolapse of the bladder, potentially resulting in death.
Nan Da Bian (Difficulty in Defecation) arises from the disharmony of the Five Zang Organs, where Yin and Yang are biased towards excess or deficiency, specifically indicating that the San Jiao (Triple Burner) is not harmonious, causing cold and heat to knot together.
The Stomach is the sea of water and grain; the essence of water and grain transforms into Ying Qi (Nutritive Qi) and Wei Qi (Defensive Qi), while the dregs are transported through the Large Intestine for excretion. Since the Five Zang Organs and San Jiao are not harmonized, cold and heat stagnate and obstruct, accumulating between the stomach and intestines. The stomach and intestines are inherently solid, and when combined with the invasion of cold and heat qi, the accumulation cannot be dispersed, thus causing difficulty in defecation.
It is also stated: Pathogens in the Kidney can also cause difficulty in defecation. This is because when the Kidney is affected by pathogens, its deficiency fails to control urination, leading to frequent urination. Consequently, body fluids become dry and depleted, the stomach and intestines become dry and astringent, resulting in difficult defecation.
Furthermore, individuals suffering from Ke Li (Wasting-Thirst Syndrome/Diabetes Mellitus) also experience difficulty in defecation. This is because body fluids are exhausted, causing dryness in the stomach and intestines.
Palpating the pulse at the Cun Kou (Inch Port) before the Ren Ying (Human Welcome) point on the left hand corresponds to the Hand-Shao-Yin Heart Meridian. A deep pulse indicates Yin; if Yin is Excess, the patient suffers from constipation, difficult defecation, abdominal distension, heaviness of the four limbs, fever, and gastric distension discomfort. If the pulse at Guan (Carpal) on the right hand is Yin Excess, it indicates Spleen Excess, characterized by a sensation of hardness like a prison within the intestines and difficult defecation. A tight and slippery pulse, with a slightly wiry Fu Yang (Foot-Yang) pulse, typically suggests abdominal distension; if there is no distension, there must be difficult defecation and foot pain, which is the downward transmission of deficiency-cold from above. Methods involving decoctions, moxibustion/ironing, acupuncture, and stone therapy have separate specific formulas. Nourishing and guiding exercises are attached hereafter.
The "Yang Sheng Fang · Dao Yin Fa" (Prescriptions for Health Preservation · Guiding and Pulling Method) states: Lie supine, extend both hands straight, and knead the left and right hypochondrium. This eliminates difficulty in defecation, abdominal pain, and cold in the abdomen. Inhale through the mouth, exhale through the nose, swallow the warm qi dozens of times, and the illness will heal.
