The purpose of drinking more water is only to make the kidneys produce more urine, and through the excretion of urine, to promote the excretion of stones along with urine, and to shorten the process of kidney stone pain, but drinking water is not a pain relief measure, instead, after drinking more water and urinating more, it may cause spasm of the ureter during the movement of stones, and instead produce more intense pain. If kidney stones are to be treated non-surgically, it is necessary to drink more water because the only way to expel the stones is through urine, plus the peristalsis of the ureter itself, plus a certain gravitational effect to expel the stones, and the flushing and carrying of urine accounts for the most important role in stone removal, so patients need to drink more water. If you drink more water, exercise more and cooperate with medication, the stone will be expelled as soon as possible, the pain caused by the stone will be shortened, and the patient’s quality of life will be relatively high, but for patients with a longer stay of the stone, or after conservative treatment is not effective, you need to undergo surgery as soon as possible.
