What holmium laser does differently
Shock wave therapy from outside the body depends on the stone being soft enough to shatter, and hard calcium oxalate monohydrate or cystine stones often survive several sittings. A laser fibre placed directly against the stone dusts it into particles fine enough to wash out with urine, irrespective of density.
- Works on all stone compositions
- Dusting settings leave very little to pass
- Fine fibres fit through flexible scopes for lower pole stones
- Precise enough to work millimetres away from the ureter wall
Where the laser is used
The laser is the working tool inside several procedures rather than a procedure in itself. Depending on where your stone is, it is delivered during RIRS, URSL, mini PCNL or bladder stone removal. The same machine also treats prostate enlargement, strictures and bladder tumours.
Safety and recovery
Laser stone surgery avoids a skin incision entirely in most cases, so recovery is measured in days rather than weeks. Risks are small but real — transient burning, blood in urine, stent discomfort, and occasionally a urinary infection that needs antibiotics. These are discussed with you before consent, with what each one would feel like and when to call.
Laser Stone Surgery — common questions
Does laser damage the kidney?
No. The energy penetrates less than a millimetre beyond the fibre tip, so it fragments stone without injuring surrounding kidney tissue when used correctly.
How many sittings does laser stone surgery need?
Usually one. Very large or multiple stones occasionally need a planned second session, which is discussed in advance rather than sprung on you afterwards.
Is laser stone surgery better than ESWL?
For most stones, yes — one sitting, higher clearance, and it works on hard stones that ESWL cannot break. ESWL still suits small, soft, well-positioned stones in selected patients.
How soon can I travel after laser stone surgery?
Short local travel after two to three days is fine. Long flights are better postponed until the stent is removed and the follow-up scan is clear.
