In Kidney stone treatment by laser,is it necessary that a small instrument insert in the body?

Is it possible for doctors to emit the laser beam directly to body skin?( without inserting it to body?)

    Sorry, but no.

    In the US, it’s done under general anesthesia. The device is threaded up through the urethra, through the bladder, and up the ureter to the stone.

    You may be thinking of lithotripsy. High power ultrasound is aimed from outside to the stone.
