This is a surgery is usually used for larger stones having size of the range 2 cm. It is a minimally invasive endoscopic treatment thus avoiding most of the complications of traditional open or even laparoscopic surgery. This is the safest and quickest method for treating kidney stones effectively. It may also be used where the ureter is blocked below the kidney by some other means and in cases where non surgical measures have either failed or cannot be adopted. The procedure is carried out by a team consisting of an urologist and a radiologist specially trained in intervention radiology. Local anesthesia may be used for pain control.
During surgery, a scope or a hollow tube is placed directly into the kidney through the patient’s back and the stone is brought under direct vision. Ultrasonic waves combined with laser energy are then used to break up and remove the stone. This procedure is also effective for smaller stones that cannot be treated by other methods. Although minor post surgery complications like persistence of blood in urine, electrolyte imbalance etc are common, they will subside soon.
Some of the advantages of PCNL are:
- Removal any renal stone made easy
- Avoids larger incisions on kidney or renal pelvis etc.
- Shorter hospital stay
