This animation visualizes the procedure for laser lithotripsy, a minimally invasive treatment for kidney stones. A thin probe is inserted through the urethra and bladder, reaching the left ureter where a stone is located. A laser beam then breaks the stone (ureteric calculus) into smaller fragments that can easily pass out in the urine.
