In TCM, the relationship between the viscera is considered to be very important, and the relationship between the kidneys and the bladder is one of them.
First of all, the kidneys and bladder are both organs that belong to the urinary system. The main function of the kidneys is to filter the blood, convert excess water and waste products into urine, and drain them through the ureters into the bladder. Whereas, the main function of the bladder is to store urine and expel it from the body when needed.
Second, the relationship between the kidney and the bladder is not only anatomically adjacent, but also functionally interrelated. The kidney's filtering function and the bladder's storage function work together, and the bladder can only have enough storage space if the kidneys work properly to produce enough urine. At the same time, if the function of the bladder is abnormal, it will also affect the normal work of the kidneys. For example, if the bladder is not able to expel urine in a timely manner, it will cause urine to accumulate in the kidneys, which will increase the burden on the kidneys.
In addition, there is a meridian connection between the kidneys and the bladder. In traditional Chinese medicine, the meridians are the path for the flow of qi and blood in the human body, and there is a direct connection between the kidneys and the bladder, which makes them closely related in physiology and pathology.
Therefore, the kidney and the bladder are not only anatomically related, but also functionally related. In traditional Chinese medicine, for kidney and bladder diseases, it is often necessary to consider the relationship between the two at the same time, and take a comprehensive approach to achieve better results.
