Laser Kidney
Stone Surgery
High-precision laser technology that effectively fragments kidney stones while preserving surrounding healthy tissue — less pain, shorter stay, faster recovery.
What is Laser Kidney Stone Surgery?
Laser kidney stone surgery uses focused laser energy — delivered through a thin ureteroscope passed via the natural urinary passage — to break kidney and ureteral stones into fine dust or small fragments that pass harmlessly with urine. No skin incision is required.
Holmium:YAG Laser
The gold-standard laser in urology. The holmium wavelength is highly absorbed by all stone compositions — calcium oxalate, uric acid, cystine, struvite, brushite — making it effective where shock waves often fail.
Via Flexible or Rigid Ureteroscope
A thin fibre-optic scope is passed through the urethra and ureter to reach the stone. A laser fibre is passed through the scope's working channel to apply energy directly to the stone surface.
Two Laser Techniques
Stones can be fragmented into retrievable pieces with a basket, or "dusted" into microscopic powder that passes naturally. Dusting is ideal for large stone burdens; fragmentation is preferred when stone analysis is needed.
Precise, Tissue-Sparing Energy
The holmium laser's energy is absorbed within the first 0.5 mm of tissue, meaning the ureter and kidney parenchyma adjacent to the stone are not damaged — a critical advantage over older electrohydraulic devices.
Types of Laser Used in Kidney Stone Surgery
Different laser platforms offer distinct advantages. Dr. Anand Utture uses the most appropriate technology for each clinical scenario.
Holmium:YAG Laser (Ho:YAG)
The most widely used laser for urolithiasis. Effective for all stone compositions, versatile for both dusting and fragmentation, and safe for adjacent tissues. Used for ureteroscopic and percutaneous procedures.
Thulium Fibre Laser (TFL)
A newer laser platform offering higher pulse repetition rates and finer dusting capability. The thulium laser produces finer stone dust, potentially reducing retropulsion and improving stone-free rates for selected cases.
Laser for Tissue Ablation
In selected cases the holmium laser is also used to incise ureteral strictures, ablate small urothelial tumours encountered during ureteroscopy, and release calyceal diverticulum necks to facilitate stone access.
How Laser Kidney Stone Surgery is Performed
The procedure follows a structured sequence to ensure complete stone clearance with maximal safety.
Anaesthesia
General or spinal anaesthesia is given. Prophylactic antibiotics are administered. The patient is positioned for ureteroscopic access.
Ureteroscope Passage
A rigid or flexible ureteroscope is advanced through the urethra, bladder, and ureter under direct vision and fluoroscopic guidance to reach the stone.
Stone Identification
The stone is visualised directly. Its size, position, and approximate composition are assessed to guide laser settings and fragmentation strategy.
Laser Application
A laser fibre is passed through the scope. Energy is applied to fragment or dust the stone completely. Fragments may be retrieved with a nitinol basket.
Stent & Discharge
A temporary JJ ureteral stent is placed to support drainage. The patient is discharged same day or the following morning.
Advantages of Laser Stone Surgery
Holmium laser lithotripsy has become the preferred energy source for ureteroscopic stone treatment worldwide — for good reason.
Effective on all stone types
The holmium laser fragments every known stone composition — including hard stones like cystine and brushite that shock waves cannot reliably break.
No external incision
The laser is delivered entirely via the natural urinary passage — no skin wound, no scar, no drain.
Precise, tissue-sparing
Energy absorption within 0.5 mm prevents collateral thermal injury to the ureter or kidney — significantly safer than electrohydraulic probes.
High stone-free rates
Single-session stone-free rates of 85–95% for ureteral stones and 80–90% for kidney stones up to 2 cm — superior to shock wave therapy.
Simultaneous stone analysis
Fragments retrieved during the procedure can be sent for formal composition analysis to guide dietary changes and medications that prevent recurrence.
Day-care discharge
Most patients are discharged the same day or the following morning, with return to desk work and light activity within 3–5 days.
Minimal blood loss
No kidney puncture means virtually no risk of significant bleeding — particularly important for patients on anticoagulation.
Works when ESWL fails
Stones resistant to shock wave therapy, lower pole stones, and stones in horseshoe or transplant kidneys all respond well to laser lithotripsy.
When is Laser Kidney Stone Surgery Recommended?
Laser lithotripsy is versatile — applicable for a wide range of stone locations, sizes, and clinical scenarios where other modalities are less suitable.
Laser Surgery vs. Other Kidney Stone Treatments
Understanding where laser lithotripsy excels helps Dr. Anand Utture choose the right approach for your specific stone.

What to Expect Before, During & After Laser Stone Surgery
Preparing for the Procedure
Dr. Anand Utture will arrange pre-operative tests including a urine culture to ensure any infection is treated before surgery, as operating in an infected urinary tract raises complication risk significantly.
Imaging — typically a non-contrast CT of the kidneys, ureters, and bladder (NCCT KUB) — is reviewed to map stone size, density, and position. Blood tests assess kidney function and clotting.
You will be asked to fast for 6 hours before the procedure. Any blood-thinning medications are paused in consultation with your prescribing doctor.
Recovery & Post-Operative Care
A temporary JJ ureteral stent is usually placed at the end of surgery to support drainage while post-operative swelling settles. This stent is removed after 1–2 weeks as a brief outpatient procedure.
Common stent symptoms — frequency, mild urgency, occasional blood in urine — are expected and resolve after stent removal. Drinking plenty of fluids accelerates recovery and helps clear stone dust.
Most patients return to desk work within 3–5 days. Heavy lifting and strenuous exercise are avoided until after stent removal. A follow-up imaging study confirms stone clearance.

Frequently Asked Questions — Laser Kidney Stone Surgery in Mumbai
What is laser kidney stone surgery?
Laser kidney stone surgery uses a holmium:YAG laser delivered through a thin ureteroscope — passed via the natural urinary passage without any skin cut — to break stones into fine dust or small fragments that pass harmlessly with urine.
Is laser stone surgery painful?
The procedure is performed under general or spinal anaesthesia so there is no pain during surgery. Mild discomfort from the temporary ureteral stent placed at the end of the procedure is common but manageable and resolves after stent removal at 1–2 weeks.
What stone sizes and types can be treated with laser?
Holmium laser lithotripsy is effective for stones of virtually all sizes in the ureter and kidney, and for all stone compositions — including hard stones like cystine, calcium oxalate monohydrate, and brushite. For very large stones (above 2 cm) laser may be combined with percutaneous access (Mini-PCNL).
How long is recovery after laser stone surgery?
Most patients are discharged the same day or the following morning. Desk work and light activity are typically resumed within 3–5 days. A follow-up CT or X-ray is arranged 4–6 weeks after surgery to confirm complete stone clearance.
Is a stent always required?
A temporary JJ ureteral stent is placed in most cases to protect the ureter and maintain drainage while swelling settles. Dr. Anand Utture will discuss this decision based on your individual findings.
Will laser surgery prevent future kidney stones?
Laser surgery removes the existing stone but does not prevent new ones from forming. A fragment retrieved at surgery can be sent for stone composition analysis — identifying the stone type guides targeted dietary modification and medication to reduce the risk of recurrence.
