Bladder stones are a common type of urinary system calculus. Generally, stones with a diameter greater than 1.5 centimeters require surgical treatment. Currently, minimally invasive surgery is performed, which is transurethral ureteroscopic holmium laser lithotripsy. This involves inserting a ureteroscope through the urethra into the bladder, locating the bladder stones under direct vision, and using a holmium laser fiber to fragment them, while simultaneously extracting the broken pieces.
