Laser is a special form of light used to treat kidney stones .Lasers are used during operation and are focussed on stones in the kidneys or ureter(tube between the kidney and urine bladder).
The laser, once engaged causes destruction of stones.The dusts gets washed out in urine.A small plastic tube called “stent” is usually placed following laser treatment.
The stent stays for few weeks and later its removed.It facilitates passage of the stone pieces and also helps in healing .The hospital length is usually an overnight stay.With modern lasers the stone clearance rate is excellent.
