Percutaneous Nephrolithotomy (PCNL) — the most effective treatment for large kidney stones above 2cm. Expert surgery by Dr. Kumar Rajesh Ranjan, M.Ch. Urology. 85–95% stone clearance. Ayushman Bharat accepted. Call 091222 37338.
PCNL (Percutaneous Nephrolithotomy) is a minimally invasive surgical procedure to remove large kidney stones. The word "percutaneous" means "through the skin" — a small 1cm hole is made in the back, a telescope (nephroscope) is passed directly into the kidney, and the stone is broken and removed fragment by fragment.
PCNL is the most effective single-session treatment for large kidney stones — achieving 85–95% stone clearance in experienced hands. It is significantly better than ESWL (shock wave therapy) and URSL (laser ureteroscopy) for stones above 2cm in size, where these procedures have much lower clearance rates.
PCNL is recommended in specific situations where it offers significantly better outcomes than other stone treatments. Your urologist will review your CT scan and advise the best approach.
Kidney stones above 2cm in size — PCNL achieves 85–95% clearance in a single session versus 40–60% with ESWL and 70–80% with laser ureteroscopy for the same stone size.
Branching stones that fill the entire kidney collecting system — only PCNL can effectively remove these large, complex stones in one or two sessions. Cannot be treated by any other method.
Some stone types are extremely hard and resistant to shock wave therapy (ESWL). PCNL breaks them mechanically regardless of stone hardness — ideal for calcium oxalate monohydrate stones.
If shock wave therapy (ESWL) or laser ureteroscopy (URSL) has failed to clear the stone — PCNL is the definitive next step. Also for stone fragments (steinstrasse) blocking the ureter after ESWL.
Horseshoe kidney, pelvi-ureteric junction (PUJ) obstruction, calyceal diverticulum stones — special anatomical situations where PCNL is often the most effective or only practical approach.
Recurrent kidney stones causing hydronephrosis (kidney swelling) — multiple stones in one kidney or bilateral stones where comprehensive clearance is needed in a single procedure.
Stone size on CT scan is the primary factor determining which treatment is best. Here is a simple guide — your urologist will advise based on your individual CT scan findings.
Three main kidney stone treatments — compared across key parameters to help you understand which is best for your stone.
| Parameter | 🔵 PCNL (Our Specialty) | 💙 URSL Laser | ⬛ ESWL Shock Wave |
|---|---|---|---|
| Best Stone Size | Above 2cm | 5mm – 2cm | 5mm – 1.5cm |
| Clearance Rate (>2cm) | 85–95% | 70–80% | 40–60% |
| Anaesthesia | General / Spinal | General / Spinal | No anaesthesia |
| Cuts on Skin | 1 small hole (1cm) in back | No cuts — through urethra | No cuts — external |
| Hospital Stay | 2–3 Days | Day Care / 1 Night | No admission |
| Staghorn Stones | Excellent | Not suitable | Not effective |
| Hard Stones | Excellent (mechanical) | Good (laser) | Poor |
| Recovery Time | 1–2 Weeks | 3–5 Days | Immediate |
| Multiple Sessions | Usually 1 session | Sometimes 2 sessions | Often 3–5 sessions |
| Ayushman Bharat | ✅ Covered | ✅ Covered | Check eligibility |
From hospital admission to going home — a complete guide to what you can expect during your PCNL surgery at Satyadev Hospital, Patna.
CT scan KUB (to map stone precisely), blood tests (CBC, RFT, coagulation, urine culture), ECG, anaesthetic review. Fasting from midnight before surgery. IV line and urine catheter placed.
⏱ Day before or morning of surgeryGeneral or spinal anaesthesia administered — completely comfortable throughout. You are positioned face-down (prone position) on the OT table so the surgeon can access the kidney from the back.
⏱ 15–20 minutes setupUnder X-ray guidance (fluoroscopy), a needle is precisely placed through the skin into the kidney. A wire is then passed, and progressively larger dilators create a 1cm channel (tract) from skin to kidney.
⏱ 15–20 minutesA nephroscope (telescope) is inserted through the tract. The stone is visualised directly — then broken using an ultrasound, pneumatic, or laser energy probe. Fragments are removed with graspers until the kidney is clear.
⏱ 45–90 minutes (varies by stone size)A nephrostomy tube (drain from kidney through skin) is placed at the end of surgery — allowing drainage, monitoring for bleeding, and a route for any second-look procedure if needed. Usually removed before discharge.
⏱ Last 5 minutes of surgeryRecover in monitored ward for 24–48 hours. Nephrostomy tube removed when drainage is clear (Day 1–2). X-ray or ultrasound to confirm stone clearance. Discharge Day 2–3 with post-op instructions.
⏱ Home in 2–3 DaysMost patients recover comfortably within 2 weeks after PCNL. Here is what to expect at each stage.
Surgery done. Recovery room. IV fluids and pain relief. Monitoring vitals and drain output overnight.
Walking starts. Nephrostomy tube removed if drainage is clear. Diet progresses. Stents may be placed.
X-ray confirms stone clearance. Discharged home with oral antibiotics and pain tablets.
Light activity at home. Avoid lifting. Stent (if placed) removed at 2–4 weeks. Follow-up at clinic.
Return to full normal activity and work. Kidney function check. Stone composition analysis for prevention.

These symptoms indicate a kidney stone emergency — call 091222 37338 and come to Satyadev Hospital immediately.
Fever above 38.5°C combined with kidney or flank pain — indicates obstructed, infected kidney (pyonephrosis). A urological emergency requiring immediate drainage and IV antibiotics.
Any kidney stone in a patient with one kidney or a transplant kidney — complete obstruction means zero urine output and acute kidney failure. Immediate hospital assessment required.
Kidney stone pain not responding to any painkiller — may indicate complete ureteric obstruction or stone impaction. IV pain relief and urgent imaging needed at hospital.
Complete absence of urine — bilateral obstruction by stones or obstruction in a single kidney. Acute kidney failure developing — emergency nephrostomy or stent placement needed urgently.
Visible blood in urine with clots or heavy bright red bleeding — can indicate stone trauma or rarely tumour. Needs urgent evaluation with ultrasound and urine cytology.
Cannot keep any food or fluids down with severe kidney pain — dehydration worsening stone pain and kidney function. IV fluids and pain control needed at hospital immediately.
