Lithotripsy Treatment

What are Kidney Stones?

 

Kidney Stones are crystal-like masses of salts and minerals, such as calcium in combination with either oxalate or phosphate, such as calcium oxalate, that form when the crystals precipitate in the urine inside the kidney. Stones can vary in size from a grain of sand to more than an inch in diameter. They build up gradually, and can stay in your kidneys or can be found anywhere in the urinary tract. A number of factors are thought to influence the development of kidney stones. Doctors do not always know what causes a stone to form. Some suggested causes are diet, climate, infection and metabolic disorders.

 

When stones grow too large to pass out of the body naturally, they can obstruct normal urine flow and may cause sudden and severe pain. Other symptoms may include bloody urine, burning during urination, infection, nausea and vomiting. Permanent relief can only be gained by removal of the stones.

 

What is Extracorporeal Shockwave Lithotripsy?

 

“Lithotripsy,” from the Greek meaning “stone crushing,” is an application of technology for treating stones in the kidneys, ureters and bladder. The term “extracorporeal” refers to the fact that the treatment is non-invasive, using shockwaves directed from outside the body. The stone to be treated is targeted with the use of x-ray or ultrasound. Multiple high-energy pressure waves are then focused on the stone until it breaks into tiny particles, which can be passed naturally from the urinary system.

What are the Benefits of Extracorporeal Shockwave Lithotripsy?

 

A major benefit of extracorporeal shockwave lithotripsy is that it is a non-invasive procedure. Lithotripsy is usually performed on an outpatient basis with reduced treatment and recovery times.

 

What are the Risks Associated with Extracorporeal Shockwave Lithotripsy?

 

Lithotripsy is usually safe. Historically, occurrence of complications is low. Possible complications can include bleeding around your kidney, kidney infection or pieces of stone left behind.

 

What Happens Before the Lithotripsy Procedure?

 

Some laboratory tests are required prior to your procedure. The tests will vary depending upon the type of anesthesia, if any, you will receive during treatment, your age, any medical conditions you may have or any medications you take. Some medications must be discontinued prior to treatment. Follow your physician’s specific instructions regarding eating or drinking prior to your treatment. You will be informed by your physician about the procedure to be performed and you will be asked to sign an informed consent for this procedure.

 

What Happens During the Procedure?

 

Your treatment will typically proceed in the following manner:

 

  • You will be comfortably positioned on the patient treatment table.

  • Precise location of the stone(s) will be determined by the use of fluoroscopy (x-rays).

  • The shockwave cushion will be placed against the side of your body. A series of wave impulses will be directed through
     your body, fragmenting the stones, until they are pulverized.

  • While being treated with lithotripsy, your anesthesiologist or nurse will care for you to make sure that you are comfortable and safe
    during the treatment. The treatment will last 30-45 minutes.

  • Your physician will follow the fragmentation process via video x-ray equipment and carefully monitor the entire procedure.

  • Mild soreness may occur at the treatment site after lithotripsy. In some instances, you may never know that you had lithotripsy.

 

What Happens After the Procedure?

 

  • After the procedure, you will remain in the recovery area until the medication given during treatment wears off.

  • You may have soreness in the back or flank area. This usually disappears after several days. The treatment can cause blotches or
      bruises on the back where the pressure wave enters the skin. These marks usually cause only minimal discomfort and should
      disappear in a short time.

   • You will most likely have some pain after treatment, as the pulverized fragments of stone are passed down the tube from the kidney
      to the urinary bladder. Pain medication prescribed by your doctor should help with this discomfort.

   • A small percentage of patients may have severe pain and/or obstruction from the failure of the stone fragments to pass.

   • Your urine may have a red tinge for several days after treatment, but blood loss is usually minimal.

   • Stone fragments should begin to pass within 24 hours of treatment, although a delayed passage is not unusual.

   • If your stone is greater than one inch in diameter or if you have multiple stones that have an aggregate diameter greater than one
     inch, you may require more than one treatment.

   • You will receive specific written after care instructions when you are ready to go home.

   • Because you have received medications during your treatment, you must have someone drive you home.
