Surgical Procedures for Kidney Stones

Surgical Procedures for Kidney Stones

Surgery is done when the stone is too large to pass in the urine, blocks urine flow, or damages the urinary tract. It can also be done to prevent a kidney infection or kidney failure. Stones that are very large or in a spot that is hard to get to with extracorporeal shock wave lithotripsy (ESWL) can be removed. Options include:

Percutaneous Nephrolithotomy

A small cut is made in the back to get to the kidney. A nephroscope is a tube placed into the kidney. Lights, a camera, and tools are used through the tube. Once the stone is reached, it can be removed through the tube. Sometimes, the stone must be broken into smaller pieces with shock waves. A small tube may be placed into the kidney to drain urine while it heals.

Ureteroscopy

A tube is passed through the urethra and bladder, and into the ureter. Lights, camera, and tools can be used through the tube. Once the stone is reached, it can be removed through the tube. Sometimes, the stone must be broken into smaller pieces with a laser. A stent may be left in place to keep the ureter open as it heals. The stent will be removed after the ureter heals.

Open Surgery

Though rare, open surgery may be needed if the stone is very large or has an odd shape. This can keep urine from flowing out of the kidney. A long cut is made along the side to get to the kidney. Once the stone is found, it is taken out. Recovery time with open surgery is longer than with the other types.
