Laser Kidney Stone Surgery No cuts. No scars. Home in a day.
How holmium and thulium lasers turn kidney and ureteric stones into fine dust through the natural urinary passage, and what to expect before, during and after.
What is laser kidney stone surgery?
Laser kidney stone surgery (laser lithotripsy) uses a thin scope passed through the urethra to reach the stone, then a holmium or thulium laser breaks it into dust or tiny fragments. There is no skin incision. Most patients go home the same day or next morning and return to desk work in 3–5 days.
Precise energy, only where the stone is.
The laser and technique are chosen for each stone based on its size, hardness and position on the CT scan.
Holmium:YAG laser
Absorbed by every stone type, including hard cystine and brushite stones that shock waves often cannot break.
Thulium fibre laser
Higher pulse rates create finer dust with less stone movement (retropulsion), which helps clear selected stones faster.
Dusting vs. fragmenting
Large stone burdens are "dusted" to powder that washes out. Fragmenting leaves pieces that can be removed and sent for stone analysis.
Tissue-sparing
Laser energy is absorbed within about 0.5 mm, so the ureter and kidney lining around the stone are protected.
How the surgery is performed
The procedure usually takes 45–90 minutes, depending on the size and number of stones.
- 01
Anaesthesia
General or spinal anaesthesia, with preventive antibiotics. You feel nothing during the procedure.
- 02
Scope passage
A rigid (URS) or flexible (RIRS) scope travels up the natural urinary passage to the stone.
- 03
Stone mapping
The stone is seen directly, and its size, position and hardness guide the laser settings.
- 04
Laser lithotripsy
The laser dusts or fragments the stone. Pieces are retrieved with a fine basket if needed.
- 05
Stent & discharge
A temporary JJ stent supports drainage. Home the same day or next morning.
When laser surgery is recommended
- ✓Ureteric stones, at any levelUpper, mid or lower ureter, especially if they are causing pain or blockage.
- ✓Kidney stones up to about 2 cmTreated through a flexible scope (RIRS) with high single-session clearance.
- ✓Hard stones or failed ESWLCystine, calcium oxalate monohydrate and brushite stones, or stones left after shock-wave treatment.
- ✓Patients on blood thinnersWith no kidney puncture, the bleeding risk is much lower than with PCNL.
- ✓Single, horseshoe or transplant kidneyProtects kidney tissue when kidney reserve matters most.
Stone size guide
A simple way to understand which approach usually fits. The final plan depends on your CT scan.
Very small stones (under about 5 mm) often pass on their own with medication and fluids.
Laser vs. ESWL vs. Mini-PCNL
| Feature | Laser (RIRS / URS) | ESWL (shock wave) | Mini-PCNL |
|---|---|---|---|
| Skin incision | None | None | Small keyhole |
| Works on hard stones | Yes | Often not | Yes |
| Best stone size | Up to ~2 cm | Up to ~1.5 cm | Over 2 cm |
| Hospital stay | Day care / 1 night | Day care | 1–2 days |
| Stone-free rate (ureteric) | 90–95% | 60–80% | Not typically used |
| Stone analysis possible | Yes | No | Yes |
| Repeat sessions | Rarely | Often | Rarely |
Your recovery, week by week.
Surgery
45–90 minutes under anaesthesia. Walking within a few hours.
Home
Same-day or next-morning discharge with oral medicines.
Back to work
Desk work and light activity. Drink plenty of fluids.
Stent removed
A quick outpatient step. Stent discomfort settles.
Clearance scan
Imaging confirms you are stone-free, and a prevention plan is set.
Common questions, answered.
Is laser kidney stone surgery painful?+
No. It is done under general or spinal anaesthesia, so you feel nothing during surgery. Afterwards most patients need only oral painkillers. Mild burning or frequency from the temporary stent is common and settles once it is removed.
How long is the recovery?+
Most patients go home the same day or the next morning and return to desk work within 3–5 days. Heavy lifting and strenuous exercise are avoided until the stent is removed, usually after 1–2 weeks.
What size of stone can be treated with laser?+
Laser surgery through a scope (RIRS or URS) suits ureteric stones of any size and kidney stones up to about 2 cm. Larger kidney stones are usually better treated with Mini-PCNL, which also uses a laser. The choice is made after reviewing your CT scan.
What does laser stone surgery cost in Mumbai?+
The cost depends on the hospital, room category, stone size and location, the laser used, and whether a stent is needed. Most health insurance policies cover it. Share your CT report with the clinic for a written estimate.
Will I need a stent?+
Usually yes. A thin temporary JJ stent keeps urine draining while swelling settles. It is removed after 1–2 weeks in a short outpatient procedure.
Can stones come back after surgery?+
They can if the underlying cause is not addressed. Fragments collected during surgery can be analysed, and you receive a diet, fluid and medication plan based on your stone type to lower the risk.
Is laser better than ESWL (shock wave)?+
For hard stones, lower-pole kidney stones and ureteric stones, laser surgery generally gives higher single-session clearance than ESWL. ESWL avoids a scope but may need repeat sessions. The right choice depends on stone size, density and position.
