O tratamento da litíase urinária na faixa pediátrica, com o uso de métodos minimamente invasivos, representa uma alternativa cada vez mais atraente. O presente trabalho objetiva apresentar resultados de litotripsia extracorpórea como tratamento minimamente invasivo de litíase urinária na infância. Métodos AbstractObjective: urinary lithiasis affects between five and 10% of the human population during their lifetime, only 2-3% of whom are children. Therapy of urinary lithiasis in the pediatric age group with minimally invasive methodology represents an attractive alternative. This study presents results of extracorporeal shockwave lithotripsy, a minimally invasive methodology, for the treatment of urinary lithiasis in children.Methods: in the period between September 1991 and September 2000, 87 children were submitted to extracorporeal shockwave lithotripsy; as six of them presented with two calculi 93 urinary calculi were treated over that period. The Dornier-Philips lithotriptor was used in the procedures.Results: Pelvic, superior and medium caliceal calculi were fragmented and eliminated in 87.7% and 77.8% of cases, respectively. Inferior caliceal stones were eliminated in 64.7% of cases. Only one of the three patients with staghorn calculi became stone-free after therapy (33.3%). All patients with ureteral calculi were stone-free after therapy. Bladder stones were fragmented and eliminated in 60% of cases.
