Percutaneous nephrolithotomy removes large kidney stones through a keyhole of about one centimetre in the back.
- Anaesthesia
- General
- Hospital stay
- Usually 1 to 3 days
- Incisions
- One keyhole, about 1 cm
- Back to routine
- Usually 1 to 2 weeks
General guidance. Your own plan, timings and risks are discussed at consultation.
How it works
The 3D view follows each stage as you read.
Precise access
Precise access
Guided by X-ray or ultrasound, a fine needle is passed through the back into the kidney, right where the stone sits.
Creating a keyhole
The track is gently widened to about a centimetre so a scope can enter the kidney.
Breaking and removing the stone
The stone is broken with laser or ultrasonic energy and the fragments are lifted out through the keyhole.
Drainage and healing
A small drainage tube or stent may stay for a short time. The keyhole heals with a small scar.
Who it helps
- Large kidney stones
- Staghorn stones
- Stones not cleared by other methods
Recovery
Days 1 to 3
Hospital stay while drainage and pain are monitored.
First week
Mild soreness around the keyhole is managed with tablets.
1 to 2 weeks
Most people return to desk work and light activity.
Follow-up
Imaging confirms the kidney is clear of stones.
Risks to know about
Bleeding, infection and, uncommonly, injury to nearby organs. These are discussed in detail before surgery.
Questions patients ask
Why PCNL rather than laser through the urethra?
For large stones, PCNL usually clears the kidney in fewer sessions.
Is the scar large?
No. The keyhole is about a centimetre across.
Other treatments
Each one has its own step-by-step guide with a 3D walkthrough.
