Medium-sized kidney stones are removed by which method?

Kidney stones are hard deposits of minerals and salts that form inside the kidneys. They can vary in size from tiny crystals to larger stones. The treatment method depends on the size and location of the stone. Small stones may pass naturally through the urinary tract, but medium-sized kidney stones often require medical intervention.

The most common treatment for medium-sized kidney stones is lithotripsy. Lithotripsy is a non-invasive medical procedure that uses high-energy shock waves to break the stones into smaller fragments. These smaller fragments can then pass naturally through the urinary system without surgery. The procedure is usually performed under local or general anesthesia and monitored using imaging techniques like ultrasound or X-rays.

Other options are not suitable for medium-sized stones:

• 
  

  Dialysis is a treatment for kidney failure, not for removing stones.

  
  


• 
  

  Excretion is the natural passing of very small stones and does not work for medium-sized stones.

  
  


• 
  

  Laser treatment is used in some specific cases but is less common than lithotripsy for medium-sized stones.

  
  

Understanding lithotripsy is important in human biology and medical science because it highlights how non-invasive techniques can treat common urinary disorders effectively. Lithotripsy is a safe and widely used method, minimizing complications, reducing hospital stay, and allowing patients to return to normal activities quickly.

The procedure also demonstrates the interaction of physics and biology in medicine, as shock waves generated outside the body are precisely focused on the stone to fragment it, illustrating the practical applications of both energy waves and human anatomy knowledge in healthcare.
