A comprehensive guide to ESWL, the non-invasive procedure that breaks kidney and ureteric stones using shock waves.
Treatment begins with
Assessment
Procedure
Stone Passage
Follow-up
This procedure is considered for small to medium kidney or ureteric stones in a suitable location.
You may need this if...
These signs may indicate that this treatment is the recommended course of care:
- Kidney stones smaller than around 2 cm
- Ureteric stones in an accessible location
- Stones not responding to medical expulsive therapy
- Suitable stone composition on imaging
A urologist's evaluation confirms whether this treatment is the right option for you.
What is ESWL?
ESWL uses focused shock waves from outside the body to break stones into small fragments that pass naturally in the urine, without any incision.
The entire procedure is performed from outside the body, with no cuts or scars.
When This Treatment is Considered
This procedure is considered for small to medium kidney or ureteric stones in a suitable location.
- Kidney stones smaller than around 2 cm
- Ureteric stones in an accessible location
- Stones not responding to medical expulsive therapy
- Suitable stone composition on imaging
The Care Pathway
1. Assessment
Imaging confirms stone size, number and location to check suitability for ESWL.
2. Procedure
Shock waves are focused on the stone under brief sedation or anesthesia, usually as a day-care procedure.
3. Stone Passage
Stone fragments pass in the urine over the following days to weeks.
4. Follow-up
Imaging confirms that the stone has cleared and checks for any remaining fragments.
“Your care team supports you through every stage, from evaluation to recovery and follow-up.”
Expected Benefits and Possible Risks
ESWL avoids any incision and has a quick recovery. Outcomes depend on stone size, location and composition.
Every treatment has potential risks. Your care team will discuss your individual risks before treatment.
Recovery & Follow-up
Most patients resume normal activity within a day or two, with stone fragments passing over the following weeks.
Your care plan includes fluid intake guidance, pain relief if needed, and follow-up imaging to confirm the stone has cleared.
Careful monitoring, follow-up testing and guidance all play an important role in achieving the best possible outcome.
Questions to Ask Your Care Team
- 1.Am I a good candidate for ESWL?
- 2.How many sessions might I need?
- 3.What does recovery involve?
- 4.What if the stone doesn't fully clear?
- 5.How can I prevent new stones from forming?
