论曰∶肿从内起，坚块四肢游肿，名为石水，其根在膀胱。盖肾主水，与膀胱合。膀胱
者，州都之宫，津液藏焉，气化则能出矣。今肾虚则膀胱气弱，膀胱气弱，则不能化气，而
隐滞不通，水液停结于脐腹间，故其证胸腹鼓满，按之如石，胁下胀痛，其脉沉迟，身体发
热，四肢头面皆肿也。

Commentary states: Edema originates internally, characterized by hard masses and wandering swelling in the four limbs; this condition is named Shi Shui (Stone Water), with its root in the Bladder. The Kidney governs water metabolism and pairs with the Bladder. The Bladder is the palace of the Zhou Du (a term referring to the reservoir for body fluids), where body fluids are stored and can be excreted through Qi transformation. Currently, Kidney deficiency leads to weakness of Bladder Qi; when Bladder Qi is weak, it cannot perform Qi transformation, causing fluids to stagnate invisibly and obstruct flow. Fluids accumulate and knot in the umbilical and abdominal regions. Therefore, the symptoms include distension and fullness of the chest and abdomen, hardness like stone upon palpation, distending pain under the hypochondrium, a deep and slow pulse, feverish sensation in the body, and edema of the four limbs, head, and face.
