How large a kidney stone can be blasted with lithotripsy?

Lithotripsy can effectively treat kidney stones that are up to about 2 centimeters (20 millimeters) in size. Stones larger than this may require alternative treatments, such as ureteroscopy or percutaneous nephrolithotomy. The effectiveness of lithotripsy can also depend on the stone's composition and location within the kidney. Proper assessment by a healthcare provider is essential to determine the best treatment approach.
