Percutaneous Nephrolithotomy (PCNL)

Percutaneous

Percutaneous Nephrolithotomy (PCNL)* is the best treatment for large stones in the kidney . General anesthesia is needed to do a PCNL . PCNL involves making a half-inch incision* (cut) in the back or side, just large enough to allow a rigid telescope (nephroscope) to be passed into the hollow center part of the kidney where the stone is located .
An instrument passed through the nephroscope breaks up the stone and suctions out the pieces . The ability to suction pieces makes PCNL the best treatment choice for large stones .
After the PCNL, a tube is usually left in the kidney to drain urine into a bag outside the body . This will also help stop any bleeding . The tube is left in overnight or for a few days . You may have to stay in the hospital overnight after this operation .
Your urologist may choose to do X-rays while you are still in the hospital to see if any stone pieces remain . If there are any, your urologist may want to look back into the kidney with a telescope again to remove them . You can begin normal activities after about one to two weeks .

Other SurgeryOther kidney surgery is rarely used to remove stones . Open, laparoscopic* or robotic surgery may be used only if all other less invasive procedures fail .
