The formation of kidney stones is mainly due to the stimulation of various reasons, leading to changes in the composition of urine, causing the gradual precipitation of urinary salt crystals and the formation of stones. Kidney stones are one of the common lesions in the urinary system, and the causes of their occurrence are related to abnormalities in the development of the urinary system, urinary tract infections, urinary tract obstruction, and daily life and dietary habits. As a result of the above factors, the composition of urine will be changed, such as: urate, phosphate, oxalate content is increased and so on. When the content of the above mentioned uric salts increases gradually, especially when the urine is concentrated, the uric salts will form crystals and precipitate out of the urine. These urinary salt crystals form the core of kidney stones. With the continuous action of the above triggering factors, it will lead to the continuous development and enlargement of the urinary salt crystals, and eventually form kidney stones. For patients who have been examined and found to have kidney stones, it is important to have regular treatment under the guidance of a doctor, and at the same time pay attention to adjusting the daily dietary habits, drinking more water and exercising more, so as to try to expel the stones and reduce the impact of the lesion on the patient.
