Even though kidney stones are small, they can cause blood in the urine, nausea, vomiting and a lot of pain — sometimes worse than child labor pains. Fortunately, stones that are less than two centimeters, or about one inch, in diameter may be successfully treated using shock waves in a procedure called lithotripsy.

Extracorporeal shock wave lithotripsy (ESWL) is the most commonly used treatment to eliminate kidney stones. It works by targeting shock waves outside the body through skin and tissue at kidney stones, causing them to eventually break and crumble into tiny pieces that can pass in urine. The decision to have ESWL is based on the size, shape and location of the stone, as well as general and kidney health. Some people who may not be candidates for the procedure include pregnant women, and those who are obese or have bleeding disorders, infections or severe skeletal abnormalities.

Lithotripsy usually is performed using light sedation or some form of anesthesia. The patient is positioned on the exam table on top of a soft, water-filled cushion. High-energy shock waves, which may cause a light tapping sensation, are then directed at the kidney stones to break them up. The procedure usually takes about 45 minutes to an hour followed by an hour or two in the recovery room. Most patients go home the same day as their procedure and can return to normal activities in two to three days. They may experience blood in the urine and abdominal pain for several days. 

As with any procedure, talk with your doctor to find out if ESWL is right for you. To learn more about this non-invasive treatment option for kidney stones, visit the free, online health library on the Doctors Hospital at White Rock Lake website at www.DoctorsHospitalDallas.com/Lithotripsy.
