In vivo stone comminution. (A) Implantation of a cylindrical BegoStone phantom (5 × 10 mm, D × L) into the renal pelvis via an incision in the ureter of a pig model. (B) Typical setup for SWL therapy with the animal in supine position and shock source coupling bellow inflated to establish contact with the pig; a drawing of the main lithotripter components, acoustic focusing angle, and target kidney is overlaid. (C) In vivo stone comminution results from subgroups after eliminating outliers.
