What is PCNL?
Percutaneous nephrolithotomy (PCNL) is the gold standard surgical treatment for large kidney stones (>25mm), staghorn calculi, and high stone burden unsuitable for other approaches. A small percutaneous tract (typically 26-30 mm) is created through the kidney, allowing direct endoscopic visualization and removal of stones via ultrasonic or laser lithotripsy. Single-stage complete stone removal is achieved in 85-95% of cases. PCNL provides rapid symptom relief, restores kidney function, and prevents recurrent complications from obstruction.
Who Needs PCNL?
PCNL indicated for large/complex stones unsuitable for URS or ESWL.
- Large stones >25mm in largest dimension
- Staghorn calculi involving multiple calyces
- High stone burden (total >2cm)
- Dense calcium stones resistant to ESWL
- Previous failed ESWL or URS
- Horseshoe kidney or anatomic abnormalities
- Ipsilateral ureteral stent or stricture
- Complete staghorn stones blocking entire pyelocalyceal system
The PCNL Procedure
Step-by-step surgical technique for large stone removal.
🏥 Setup & Positioning
General anesthesia. Patient prone position for optimal posterior kidney access. Fluoroscopy or ultrasound identifies stone location. Foley catheter inserted for bladder drainage. Operative site prepped and draped under sterile conditions.
📍 Percutaneous Access
Needle puncture (usually posterolateral lower pole calyx) under imaging guidance. Guidewire placement. Serial dilators enlarge tract to 24-30 Fr working channel. Amplatz sheath allows nephroscope introduction while maintaining access.
⚡ Stone Fragmentation & Removal
Nephroscope provides direct visualization of stones. Ultrasonic or laser lithotripsy fragments stones. Basket or grasper retrieves fragments. Continuous irrigation maintains visualization. Large staghorn stones may require multiple firings and repositioning.
📤 Completion & Stent Placement
Fluoroscopy confirms complete stone clearance. Hemostasis via cautery if bleeding vessels identified. Nephrostomy tube (24 Fr) placed for retroperitoneal drainage. Ureteral stent typically placed for post-operative drainage if needed.

Recovery Timeline
- Day 1: Post-operative monitoring, nephrostomy tube in place
- Day 2-3: Nephrostomy tube removed if drainage clear
- Discharge on day 2-4 with ureteral stent (if placed)

- Light activity resumption 1-2 weeks
- Full activity 4-6 weeks post-operatively
- Follow-up imaging at 4-6 weeks confirms stone-free status
Frequently Asked Questions
Percutaneous nephrolithotomy (PCNL) is minimally invasive stone removal via small percutaneous tract into kidney. Gold standard for large stones >25mm, staghorn calculi, high stone burden. Single-stage complete stone removal.
Large stones >25mm diameter, staghorn calculi involving multiple calyces, dense calcium stones, failed ESWL/URS, ipsilateral implanted stent or anatomy precluding URS.
Prone positioning, contrast retrograde pyelography identifies stone. Percutaneous puncture (usually posterolateral lower pole) over guidewire. Serial dilation creates 24-30 Fr working channel. Nephroscope allows direct stone visualization and removal via ultrasonic/laser lithotripsy.
Hospital stay 2-4 days. Nephrostomy tube removed 24-48 hours post-op. Urinary stent removed after 2 weeks. Return to light activity 1-2 weeks, full activity 4-6 weeks.
Stone-free rate 85-95% for large/staghorn stones. Residual fragments require second-look PCNL or URS. Excellent results for high-burden stones unsuitable for other approaches.
PCNL surgery ₹60,000-₹1,00,000 depending on stone complexity. Includes procedure, anesthesia, 2-3 day hospitalization. Insurance coverage available.
