Kidney stone laser lithotripsy is a procedure in which stones are crushed into smaller particles by laser through ureteroscopy and then expelled from the body. Patients need to be anesthetized for the kidney stone laser lithotripsy procedure. The main procedure involves the introduction of a fiber optic into the body through the ureteroscope after the ureteroscope is delivered to the area where the stone is located, and the laser is used to break up the stone. The laser crushes the stones into smaller particles that are then expelled from the body. Patients are treated with medications such as terazosin under the direction of their doctor after the procedure, and they need to drink plenty of fluids, with 2,000 to 3,000 milliliters of water per day. A double J-tube is usually placed, which needs to be removed after one month. Patients also need to have regular ultrasound and liver and kidney function checkups, pay attention to maintenance, eat a regular diet, and exercise moderately. Patients are advised to seek prompt medical attention for any postoperative discomfort. When patients need to undergo laser lithotripsy for kidney stones, it is recommended to go to a regular hospital for a detailed examination and have the lithotripsy operation performed by a professional doctor.
