  • Percutaneous nephrolithotomy: An operation that consists of making a path through the skin from the back to the kidney, including through which mechanisms of fragmentation of the stones are introduced and the fragments are extracted.
  • Open and laparoscopic pelyolitotomy: if the kidney stone is more than 2 cm. Of maximum diameter is recommended surgery, since the fragmentation and removal of the remains of the stone could generally many problems
