Many treatment options are available when the stone is too large. It can blocks your urinary tract, immediate treatment is needed. Dr. Sabharwal can remove your kidney stone using one of the following procedures: Extracorporeal Shock Wave Lithotripsy (ESWL): Shock waves break the kidney stone into small pieces that easily pass through your urinary tract. Percutaneous Nephrolithotomy: A thin tool called a nephroscope is used to locate and remove the kidney stone. This procedure is performed using minimally invasive surgery, which means that it only requires a small incision to accommodate the narrow nephroscope. Ureteroscopy: If you have a small stone, Dr. Sabharwal uses a ureteroscope, a narrow tube equipped with lighting and a camera, inserted through your urethra and bladder to reach your ureter and look for the kidney stones. After the stones are found, special tools are used to remove them or break large stones into smaller pieces for removal.
