[Trans-urethral bladder lithotripsy using the Lithoclast in children. Apropos of 7 cases].

We report our experience with a new simple machine for endoscopic disintegration, the "Swiss Lithoclast". The principle of this lithotriptor is based on pneumatic shock waves induced by the central compressed air system of a hospital. This device was used to treat 7 children with bladder stone (5 boys, 2 girls); their age was between 7 and 9 years (average 8.2 years). Endoscopic fragmentation was successful in all patients and all were stone free before leaving the hospital. We have found the Swiss Lithoclast to be a safe, effective and inexpensive means of performing intra-corporeal lithotripsy for bladder stone in children.
