Kidney stones fall under the category of urological diseases. If one suffers from kidney stones, it is necessary to visit a hospital and register at the urology department. Examinations such as color ultrasound and CT scans are required to precisely determine the stone's location and size, and to check if it is accompanied by spinal infection or other conditions for appropriate treatment. If the stone within the kidney is comparatively small, such as about 5 millimeters, conservative treatment to facilitate stone expulsion is generally adopted. This can be achieved through increased water intake and frequent urination, physical exercise, in conjunction with medications like stone-expelling granules and solutions to promote the expulsion of the stone from the body. If the stone is larger and causes renal accumulation of fluid or even infection, it is necessary to first control the infection before proceeding with surgical intervention.
