There are several options for kidney stones.
Shockwave lithotripsy (SWL) — SWL is the treatment of choice in many patients who need help passing a stone, and is particularly good for stones in the renal pelvis and upper ureter. A high energy shock wave is directed toward the stone, passing through the skin and bodily tissues and causing a release of energy at the stone surface. This energy causes the stone to break into fragments that can be more easily passed.
Percutaneous Nephrolithotomy (PNL) — Extremely large or complex stones, or stones resistant to shock wave lithotripsy, may require removal using a percutaneous approach. In a percutaneous approach, small telescopic instruments are passed through the skin and into the urinary tract to access the stone directly.
Ureterorenoscopy — Ureterorenoscopy is often used to remove stones obstructing the middle and lower portion of the ureter. In ureterorenoscopy, a very small telescopic instrument is passed up through the urethra and bladder and into the ureter. The telescope is moved through the ureter until it encounters the obstructing stone, which can then be removed.
Followup with your personal physician is essential.
