[Piezoelectric extracorporeal lithotripsy in children. Assessment over 3 years]

From 1987 to 1990, 45 children whose age ranged from 5 months to 14 years and who presented with urinary lithiasis underwent piezoelectrical extracorporeal lithotripsy with a Piezolith 2,300 and 2,500 system. We were able to perform the treatment without anesthesia in 53% of the children. The results were highly encouraging as, and without any severe complication; 84% of the children had no residual calculus after 3 months.
