ESWL Vs Laser Lithotripsy

When is ESWL done?

ESWL, or Extracorporeal Shock Wave Lithotripsy, is often the first choice of treatment for smaller kidney stones under 2 cm in diameter. This non-invasive procedure is commonly indicated for:

• 
  Kidney stones found in the renal pelvis or upper ureter.
• Stones that are not causing severe obstruction or infection and are 2 cm or less in diameter.

While ESWL can be considered for larger stones, the success rates lower significantly and multiple sessions might be needed. It’s important to remember that several factors influence whether ESWL is performed, such as:

• 
  The stone’s composition – notably, cystine and certain types of calcium stones respond less to ESWL.
• The patient’s body habitus – it tends to be less effective in obese patients.
• Any abnormalities in kidney anatomy which may reduce the procedure’s success.
• The type of ESWL machine used.

Therefore, ESWL isn’t a one-size-fits-all solution, but it may well be your first line of defence against smaller kidney stones.

When is Laser Lithotripsy done?

Laser lithotripsy is a medical procedure your doctor might recommend when certain challenges with kidney stones arise. Here are some situations that may merit the use of laser lithotripsy:

• 
  You have kidney stones lodged in the ureter or kidney which are too big to pass naturally. These are typically stones that have grown beyond 5-10 mm.
• Your kidney stones didn’t budge or break down after undergoing extracorporeal shock wave lithotripsy (ESWL), a non-invasive treatment for kidney stones.
• The stones have become impacted, causing severe obstruction and associated pain.
• You’re dealing with stubborn stones composed of cystine or specific types of calcium that proved resistant to ESWL.

Benefits of ESWL

Extracorporeal shock wave lithotripsy (ESWL) is a standout treatment for kidney stones, and it’s not hard to see why. Here are some of its key benefits:

• Non-Invasive: As the procedure does not involve surgical incisions, the risk of wounds or scars is removed. It’s a convenient option for many people.
• Outpatient Procedure: Typically, ESWL procedures are conducted in the OPD (out-patient department), meaning you can head home on the same day without needing an extended hospital stay.
• Light Anaesthesia: While some form of anaesthesia is still required, ESWL often calls for only sedation or a “twilight” anaesthetic instead of full general anaesthesia. It’s generally easier on the body.
• High Success Rates: ESWL boasts impressive stone clearance rates of approximately 75-90% for suitable stones. Smaller stones (less than 10mm) in the upper ureter show the highest success rates.
• Low Discomfort Level: The procedure causes minimal discomfort which usually lasts only a day or two post-procedure and can be managed effectively with pain medication.
• Fewer Surgical Risks: By avoiding a traditional surgery, ESWL sidesteps potential hazards like bleeding, infection, and other complications linked with open or endoscopic stone removal surgeries.

Benefits of laser lithotripsy

Laser lithotripsy, a modern method to treat kidney stones, comes with numerous benefits. Let’s explore them:

• Minimally Invasive: Unlike an open surgery, laser lithotripsy is a less invasive procedure involving a small scope that goes through the urethra to reach the stone. This results in lesser pain and quicker recovery times.
• High Success Rates: With stone clearance rates between 92-97%, it stands as an extremely successful treatment. The laser precisely targets and fragments even larger stones.
• Stone Composition Versatility: Regardless of the stone’s composition, laser lithotripsy can effectively break them down. It’s particularly useful for stones resistant to treatments like extracorporeal shock wave lithotripsy (ESWL).
• Outpatient Procedure: This procedure allows patients to return home on the same day, reducing downtime considerably.
• Fewer Complications: Compared to open surgeries, this treatment has lower chances of complications such as bleeding, infection or harm to surrounding tissues.
• Quicker Recovery: Patients generally experience less pain post-procedure and return to their routine faster than after more invasive procedures.
• Ability to Treat Larger Stones: Laser lithotripsy can effectively fragment larger kidney stones (up to 2 cm) that may not be suitable for ESWL.

Recovery after ESWL

After undergoing EWSL, it’s important to take certain steps to ensure a smooth recovery.

• It’s typical to spend about 1-2 hours in the recovery area before being discharged on the same day.
• Mild discomfort, bruising, or soreness in the treated area is normal. Pain medication can ease these symptoms.
• Blood in the urine may be noticed for 1-3 days post-procedure as stone fragments start to pass. Drinking ample fluids can help flush these out.
• Generally, patients can return to normal activities within 1-2 days. Strenuous exercise, however, may have to be postponed for a few days.
• Stone fragments might continue to pass for weeks post-procedure.
• Complete recovery and stone passage generally takes around 4-6 weeks but could vary based on the size and location of the original stone.

Recovery after Laser Lithotripsy

After undergoing Laser Lithotripsy, one can take these steps to ensure a smooth recovery:

• Similar to ESWL, this is typically an outpatient procedure where patients are discharged home the same day after a brief recovery period.
• Patients might feel mild burning or discomfort during urination in the initial few days as the stone fragments begin to pass.
• The doctor could place a small stent in the ureter to facilitate passage of stone fragments which could cause additional discomfort.
• Normal activities can usually be resumed within a few days. However, intensive exercise might need to be delayed for 1-2 weeks.
