Laser Lithotripsy for Kidney Stones

Published with the inputs from Dr Krishna Mohan R, Senior Consultant, Advanced Robotic And Laser Urology,  Baby Memorial Hospitals- Kozhikode

Laser lithotripsy is a minimally invasive procedure used to break kidney stones, ureteric stones, or bladder stones into smaller fragments using a laser. These fragments can then pass naturally through urine or be removed with small instruments. Laser lithotripsy is highly effective, safe, and preferred for stones that are too large, hard, or resistant to medications and other treatments.

What is laser lithotripsy?

Laser lithotripsy is a procedure where a thin, flexible scope (ureteroscope) is passed into the urinary tract. A laser beam is directed at the stone to break it into tiny pieces, which can either pass naturally or be removed.

Why is laser lithotripsy recommended?

It is usually advised when:

• Kidney or ureteric stones cause pain, blockage, or infections
• Stones are too large or hard to pass on their own
• Other methods like medications or shockwave lithotripsy are not effective

Is laser lithotripsy painful?

The procedure is performed under anesthesia, so patients do not feel pain during surgery. Mild discomfort, burning sensation while urinating, or blood in urine may occur for a few days afterward but usually resolve quickly.

How is the procedure performed?

• A thin ureteroscope is inserted through the urethra and bladder to reach the stone.
• A Holmium:YAG laser is used to fragment the stone.
• The fragments may pass naturally or be extracted with small instruments.
• Sometimes, a temporary stent (small tube) is placed to help urine flow.

What is recovery like after laser lithotripsy?

• Most patients go home the same day or the next morning.
• Normal activities can usually be resumed in 2–3 days.
• Temporary symptoms may include mild burning urination or frequent urges.
• Full recovery takes about 1–2 weeks.

Is laser lithotripsy better than other stone treatments?

Yes, in many cases. Compared to shockwave lithotripsy (ESWL) or open surgery:

• It works for stones of almost all types and sizes
• It has a higher success rate for complete stone clearance
• It avoids external cuts or large incisions
• Recovery is faster and safer

Are there any risks of laser lithotripsy?

Though uncommon, risks may include:

• Urinary tract infection
• Temporary stent-related discomfort
• Rare injury to urinary tract
• Small residual stone fragments (sometimes needing repeat procedure)
