PCNL (Percutaneous Nephrolithotomy) is the go-to procedure for large, complex, or staghorn kidney stones that don't resolve with laser or shockwave treatment. Dr. Kumar Rajesh Ranjan, M.Ch (Urology), is one of the most experienced PCNL surgeons in Patna, performing this procedure with a minimized incision, reduced blood loss, and a properly trained surgical team at Satyadev Super Speciality Hospital.
PCNL is generally recommended when other techniques like shockwave therapy or laser treatment alone are not suitable or haven't resolved the stone.
Stones larger than approximately 2cm
Stones branching through the kidney's collecting system
Stones not resolved by laser or shockwave therapy
Stones in a position that drains poorly
PCNL is performed under general anaesthesia at a well-equipped hospital. Here is a step-by-step look at the procedure.
Before the procedure, a CT scan, ultrasound, or X-ray is performed in the radiology department to precisely guide access to the kidney.
Before surgeryPCNL is performed under general anaesthesia — you are fully asleep and comfortable throughout the procedure.
10-15 minutesIn the operating room, the surgeon creates a small puncture into the kidney, guided precisely by X-ray imaging, and passes a tube through this tract.
First 15-20 minutesThe stone is broken into fragments using specialized equipment, then removed directly through the tract under continuous visualization.
45-90 minutesA nephrostomy tube is placed between the skin and kidney to drain urine directly into a drainage bag, aiding healing of the tract.
End of procedureYou are monitored closely as anaesthesia wears off, with pain managed by medication and early walking encouraged to support recovery.
Same day onward
A closer look at why PCNL is specifically chosen for large and complex stones, compared with other common techniques.
| Feature | PCNL | RIRS / Laser | Shockwave (ESWL) |
|---|---|---|---|
| Best Stone Size | Large & staghorn stones (>2cm) | Up to ~2cm | Small stones (<1cm), softer composition |
| Access | Small tract (5-15mm) in the back | Natural passage — no cuts | No cuts, shockwaves from outside |
| Single-Session Clearance | Very high, even for complex stones | High for suitable stones | Lower — often needs repeat sessions |
| Hospital Stay | 1-2 nights | Same day / overnight | Outpatient, no stay |
| Anaesthesia | General | General or spinal | Sedation or none |
Understanding what happens after PCNL helps you prepare and recover with confidence.
Most patients stay at the hospital for 1-2 days after PCNL for monitoring and recovery.
Some pain in the flank area is normal for a few days, well-controlled with prescribed medication.
Mostly liquid and easily digestible solid foods for the first two days, with IV fluids supplementing hydration.
Walking 4-6 times a day is advised after surgery — it reduces the risk of blood clots and supports recovery.
Drains urine directly from the kidney into a bag; typically removed 1-2 weeks after surgery once healing is confirmed.
Occasionally needed if some stone fragments remain, accessed through the original nephrostomy tract.
Like any surgery, PCNL carries some risk if not performed accurately — this is why choosing an experienced surgeon matters. Contact us immediately if you notice any of the following after surgery.
Fever that doesn't improve, especially combined with pain, needs urgent evaluation for possible infection.
Pain that persists despite prescribed pain relief should be reported promptly.
Bleeding is a recognized risk of PCNL — any heavy or worsening bleeding needs immediate assessment.
Redness, discharge, or leakage at the drainage tube site should be evaluated promptly.
A rare but recognized risk of the puncture-based approach, managed by our experienced surgical team to minimize this risk.
Occasionally, small fragments remain and may need a second-look procedure — your surgeon will discuss this if relevant.

Most patients stay 1-2 days after PCNL for monitoring, with the nephrostomy drainage tube typically removed 1-2 weeks after surgery.
