Percutaneous Nephrolithotomy

Percutaneous nephrolithotomy is a minimally invasive technique used to drain urine and thus remove kidney stones.

It consists of passing a special medical instrument through the skin to the kidney. Percutaneous nephrolithotomy is usually performed under general anesthesia, and the healthcare provider will make an incision in the back to insert a catheter into the kidney. The duct is then dilated and a plastic tube is inserted so that the urologist can introduce the necessary instruments to extract or spray the kidney stone.

After the procedure, a catheter is placed in the kidney and ureter to drain the urine from the kidney.
