The kidney and bladder

The function of the bladder relies on the condition of the kidney qi. Kidney qi assists the bladder in metabolizing body fluid. When the kidney qi is sufficient and its checking function normal, the bladder opens and closes regularly so as to maintain normal water metabolism. When the kidney qi is deficient, disturbance of checking function will lead to irregular opening and closing of the bladder, resulting in dysuria, incontinence of urine, enuresis, and frequency of micturition. Pathological changes in the storage and discharge of urine, therefore, are often related to both the bladder and kidney
