Laser Lithotripsy: Before Your Procedure

Skip Navigation
Laser lithotripsy

What is laser lithotripsy?

Laser lithotripsy is a procedure to treat kidney stones. It uses a laser to break the stones into very small pieces. These pieces can be removed during the procedure. Or they may pass out of the body in the urine.

You may be awake for the procedure. Or you may have medicine to make you sleep. Either way, you will not feel pain.

The doctor puts the laser and other tools into your urethra and moves them into the ureter and perhaps the kidney. The urethra and ureters are the tubes that carry urine through and out of your body.

The laser is then used to break up the kidney stones. The doctor may also place a small, flexible tube inside one of your ureters. It helps the pieces of the stone pass through your body.

Most people are able to go home the same day of the procedure.

How do you prepare for the procedure?

Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.

Preparing for the procedure

 
  • Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.
  • Understand exactly what procedure is planned, along with the risks, benefits, and other options.
  • If you take a medicine that prevents blood clots, your doctor may tell you to stop taking it before your procedure. Or your doctor may tell you to keep taking it. (These medicines include aspirin and other blood thinners.) Make sure that you understand exactly what your doctor wants you to do.
  • Tell your doctor ALL the medicines, vitamins, supplements, and herbal remedies you take. Some may increase the risk of problems during your procedure. Your doctor will tell you if you should stop taking any of them before the procedure and how soon to do it.
  • Make sure your doctor and the hospital have a copy of your advance directive. If you don't have one, you may want to prepare one. It lets others know your health care wishes. It's a good thing to have before any type of surgery or procedure.

What happens on the day of the procedure?

  • Follow the instructions exactly about when to stop eating and drinking. If you don't, your procedure may be canceled. If your doctor told you to take your medicines on the day of the procedure, take them with only a sip of water.
  •  
    Take a bath or shower before you come in for your procedure. Do not apply lotions, perfumes, deodorants, or nail polish.
  •  
    Take off all jewelry and piercings. And take out contact lenses, if you wear them.

At the hospital or surgery center

  • Bring a picture ID.
  •  
    You may need to give a urine sample. This is to make sure that you do not have an infection.
  •  
    Before the procedure, a health professional will clean the area around your urethra. He or she will also put numbing gel inside your urethra.
  •  
    You will be kept comfortable and safe by your anesthesia provider. The anesthesia may make you sleep. Or it may just numb the area being worked on.
  •  
    The procedure will take a few hours.

When should you call your doctor?

  • You have questions or concerns.
  • You don't understand how to prepare for your procedure.
  • You become ill before the procedure (such as fever, flu, or a cold).
  • You need to reschedule or have changed your mind about having the procedure.
