Percutaneous Nephrolithotomy
Percutaneous Stone Removal.
The Procedure
Disintegration & extraction of kidney stones with a telescope placed into the kidney through a small puncture in the back. This usually includes cystoscopy and x-ray screening
Normally, a full general anaesthetic will be used and you will be asleep throughout the procedure.
You will usually be given injectable antibiotics before the procedure, after checking for any allergies.
First, a small tube is inserted up the ureter into the kidney by means of a telescope passed into the bladder. You are then turned on to your face and a puncture track into the kidney is established, using X-ray guidance.

Finally, a telescope is passed into the kidney and the stone(s) extracted or disintegrated with ultrasound. A catheter is usually left in the bladder at the end of the procedure together with a drainage tube in the kidney.
It may be necessary to puncture the kidney at more than one site if you have many stones scattered throughout the kidney.
