PCNL - Keyhole Surgery for Large Kidney Stones
PCNLSpecialist surgeons onlyCashless insuranceFree follow-ups
Some kidney stones grow too large for laser-only or shock-wave treatment. Stones bigger than about 2 cm - including branched 'staghorn' stones that fill the kidney's collecting system - often cause repeated infections, blood in urine and gradual, silent loss of kidney function. Ignoring them risks permanent damage, so complete clearance in the fewest possible sittings becomes the priority for these patients.
PCNL (percutaneous nephrolithotomy) is the gold-standard treatment for large kidney stones. Through a small keyhole opening on the back - usually under 1 cm with modern Mini-PCNL instruments - the urologist reaches the stone directly, breaks it using laser or pneumatic energy, and removes the fragments immediately. Because pieces are physically extracted rather than left to pass, PCNL offers the highest single-sitting clearance rate for big stones.
At Axten Hospitals, PCNL is performed only by specialist urologists experienced in miniaturised techniques. You get one honest, all-inclusive package price covering surgery, anaesthesia, room, medicines and consumables - zero surprise billing, cashless insurance support, 0% EMI, a dedicated care coordinator and free post-surgery follow-ups until you are confirmed stone-free.

Symptoms of Large Kidney Stones
- Dull, persistent ache in the flank or back rather than sharp colic
- Repeated urinary tract infections or fever episodes
- Blood in the urine, visible or detected on testing
- Cloudy or foul-smelling urine
- Nausea, poor appetite or general tiredness
- Sometimes no symptoms at all - large stones are often found incidentally on scans
Risks of delaying treatment
- Large stones silently destroy working kidney tissue, sometimes leading to a non-functioning kidney
- Staghorn stones harbour bacteria, causing repeated infections and the risk of life-threatening sepsis
- Long-standing obstruction and infection can push patients towards chronic kidney disease and dialysis
- The bigger the stone grows, the longer and more complex the eventual surgery becomes
How is large kidney stones diagnosed?
A non-contrast CT scan (NCCT KUB) is the key investigation for large stones - it maps the exact size, branching pattern, density and position of the stone, and helps the urologist plan the safest keyhole track into the kidney. Ultrasound and X-ray KUB support the initial assessment and later follow-up.
Blood tests (creatinine, electrolytes, blood counts, sugar) assess overall kidney function and fitness for anaesthesia, while urine culture identifies any infection that must be treated with antibiotics before surgery. In selected cases a nuclear renal scan is added to measure how much each kidney is actually working.
Benefits of pcnl treatment
- Highest single-sitting clearance for stones larger than 2 cm
- Tiny keyhole incision - often under 1 cm with Mini-PCNL
- Stone fragments are removed immediately, not left to pass painfully
- Short hospital stay of usually one to two nights
- Protects long-term kidney function by relieving blockage completely
- Suitable even for hard, dense stones that resist shock-wave therapy
Types of kidney stone removal (small incision)
Non-surgical options
- ESWL (shock wave lithotripsy) - may be attempted for borderline 1.5-2 cm stones, but often needs multiple sittings with lower clearance
- Medical therapy - dissolution medicines can shrink pure uric-acid stones in selected patients, under close monitoring
Surgical & procedural options
- Standard PCNL - the classic keyhole technique for very large or staghorn stones, with excellent clearance
- Mini-PCNL - miniaturised instruments through a smaller track, meaning less pain, less bleeding and faster recovery
- Tubeless PCNL - in suitable cases no drainage tube is left in the back, allowing earlier discharge
- RIRS - flexible laser scopy through the natural passage, an alternative for moderately large stones or as a top-up for residual fragments
How the procedure is performed
PCNL is performed under general anaesthesia and typically takes 60-90 minutes. Guided by X-ray or ultrasound imaging, the urologist makes a small puncture on the back and creates a narrow track directly into the kidney's collecting system, then slides a slim telescope down this track to see the stone clearly on the monitor.
The stone is fragmented using a laser fibre or pneumatic lithoclast, and the pieces are actively suctioned or extracted through the track - this immediate removal is what gives PCNL its superior clearance for large stones. At the end, a DJ stent and sometimes a small temporary tube in the back are placed to protect the kidney while it heals.
Most patients are out of bed the same evening and go home in one to two days. Any tube in the back is removed before discharge, and the DJ stent is taken out in a short day-care visit a few weeks later, after an X-ray confirms complete stone clearance.
Recovery & aftercare
- Expect to stay one to two nights in hospital; walking resumes the same evening
- Keep the small back wound dry as advised; it usually heals within a week
- Drink 2.5-3 litres of water daily once your urologist confirms it is safe
- Avoid heavy lifting, gym workouts and long journeys for two to three weeks
- Slightly pink urine for a few days is normal; report heavy bleeding immediately
- Attend your free follow-up and stent-removal appointments without fail

FAQs about kidney stone removal (small incision)
When is PCNL preferred over laser (RIRS) for kidney stones?
PCNL is generally the best option for kidney stones larger than about 2 cm, staghorn stones, very hard stones, or multiple large stones - situations where RIRS would need several sittings. Because PCNL physically extracts fragments through a keyhole track, it achieves the highest single-operation clearance for big stones. For smaller stones, no-cut laser RIRS is usually recommended instead.
How big is the cut in PCNL surgery?
With modern Mini-PCNL instruments, the skin opening on the back is typically just 5-10 mm - about the width of a pen. It usually needs only a single stitch or a small dressing and fades into a barely visible mark. The miniaturised track also means less pain, minimal bleeding and quicker recovery compared with older, larger-track PCNL techniques.
How long will I stay in hospital after PCNL?
Most Axten patients stay one to two nights. You will be walking and eating the same evening as surgery. Any temporary tube in the back is removed before discharge, and you go home with simple oral medicines. Office work can usually resume within a week to ten days, while heavy physical work should wait two to three weeks.
Is PCNL safe? What are the risks?
In experienced hands PCNL is very safe, with decades of worldwide evidence behind it. Possible risks include bleeding, infection, or rarely injury to nearby structures, but serious complications are uncommon, especially with mini instruments and imaging guidance. At Axten, only specialist urologists perform PCNL, with anaesthesia teams and blood bank backup available, and every risk is explained honestly before you consent.
Will my whole stone be removed in one operation?
In the vast majority of cases, yes - complete clearance in a single sitting is the main advantage of PCNL. For very complex staghorn stones, a small residual fragment is occasionally left and cleared later with a short laser (RIRS) session or ESWL. A post-operative X-ray or scan is always done, and your follow-up imaging at Axten is free.
Is PCNL covered by insurance, and what does the package include?
Yes, PCNL is covered by practically all health insurance policies, and Axten offers cashless approval with major insurers. Our all-inclusive package covers surgeon and anaesthetist fees, operation theatre, laser/lithoclast charges, room, medicines, consumables and routine investigations - with zero surprise billing. Self-paying patients can also choose 0% EMI plans through our finance desk.
Can both kidneys be operated on at the same time?
If you have large stones in both kidneys, surgeons usually treat the more troublesome or obstructed side first and the other side a few weeks later, which is safer for kidney function. In carefully selected, fit patients, same-sitting bilateral surgery may be considered. Your Axten urologist will plan the sequence based on your scans, kidney function and overall health.
How do I prevent large stones from forming again?
Removed fragments are sent for stone analysis, which tells us the stone's chemical type. Based on this, you receive specific advice - typically 2.5-3 litres of fluids daily, less salt, moderated animal protein, and medicines for high uric acid or recurrent infection where needed. Periodic ultrasound checks catch any new stone early, when it can still be managed without surgery.
