General guidance. Your own plan, timings and risks are discussed at consultation.
How it works
The 3D view follows each stage as you read.
Targeting the stone
Targeting the stone
You lie on the treatment table while X-ray or ultrasound locks onto the stone's exact position.
Focused shock waves
The machine sends shock waves through the skin, focused on the stone. Most people feel a tapping sensation.
The stone breaks up
Over the session, repeated waves crack the stone into small fragments.
Passing the fragments
The fragments pass out in the urine over the following days and weeks, helped by plenty of fluids.
Who it helps
- Smaller kidney stones
- Some upper ureteric stones
Recovery
Same day
Go home after the session.
Next few days
Pink urine and a mild ache are common. Passing fragments can cause brief pain.
2 to 4 weeks
An X-ray or ultrasound checks whether the stone has cleared.
If needed
Some stones need a second session or a different treatment.
Risks to know about
Bruising, blood in the urine, pain as fragments pass, and sometimes the need for repeat sessions or another treatment.
Questions patients ask
Does ESWL work for every stone?
No. Very hard, large or lower-kidney stones often respond better to laser surgery or PCNL.
Is it painful?
Most people feel tapping or mild discomfort, which is managed with pain relief.

Each one has its own step-by-step guide with a 3D walkthrough.
