The Lithotripsy extracorporeal search result fragmentacion urolithiasis, through the application of shock waves generated externally, the Litotritor. The impact of this energy in the calculation, achieved it decays and then is removed the fragments of the stones converted to in grit through the urine.

Minimally invasive surgery: when kidney stones, for your location could not be treated with extracorporeal or by the size of the calculation (it is very large), it is perform a surgery called “Nefrolitotricia Percutaneous“. This procedure surgical consists in extracting kidney stones through an incision of a centimeter in the back, which is accessed by the kidney and removed all the lithiasis . The patient should be hospitalized after this surgery.
