Kidney stone is one of the most common urinary stones in urology, with the development of technology, the vast majority of kidney stones are treated by minimally invasive treatment, laser lithotripsy is one of the most commonly used lithotripsy tools, commonly used holmium laser, now more advanced is the mosaic laser. For kidney stones with a diameter of less than 2cm, transurethral ureteral lithotripsy can be used, which means inserting a flexible ureteral mirror through the urethra and inserting a laser into the mirror to break up the stone. For kidney stones larger than 2cm in diameter, percutaneous nephrolithotripsy is mostly used, in which an eye is made in the lumbar region, a nephrolithoscope is inserted, and a laser is inserted into the nephrolithotripsy to break up the stone, and it can be sucked out of the stone.
