MONOTHERAPY EXTRACORPOREAL SHOCK WAVE LITHOTRIPSY FOR THE TREATMENT OF STAGHORN CALCULI IN CHILDREN

Purpose: We evaluate the efficacy and parenchymal consequences of extracorporeal shock wave lithotripsy (ESWL* *Dornier Medical Systems, Inc., Marietta, Georgia.) for staghorn calculi in children.Materials and Methods: From 1991 to 1999, 16 young patients 5.5 months to 2 years old and 7 older children 6 to 11 years old were treated for complete (6) or partial (17) staghorn calculi. Infection was the main factor of lithogenesis, particularly in younger children. In 21 patients the stone burden was more than 20 mm. All patients were treated under general anesthesia using a 14 kV.

In the younger children group calculi were fragmented after 1 (11) or 2 (5) sessions. Of the 7 older children 3 required 3 (1) and 4 (2) treatment sessions. To assess the long-term...
