EDAP LT01 Lithotripter

  • Peter C. Ryan
  • Michael R. Butler


The advantages and disadvantages of piezoelectric lithotripsy are discussed with specific analysis of the EDAP LT01. A description of the EDAP LT01 is included, as well as its imaging properties and the physics of piezoelectric transduction. Installation, accommodation, and maintenance features are discussed. A total of 118 patients had 158 treatments for 134 renal and 24 ureteric calculi. Failure of imaging or fragmentation occurred in 3.9% of renal calculi and 33.3% of ureteric calculi. Six staghorn calculi were treated with a mean clearance at three months of 83.6%. The majority (68.8%) of ureteric calculi had successful treatments with the stone pushed into the kidney before treatment with extracorporeal shock wave lithotripsy (ESWL).
