DUARTE, Ricardo J. et al. Extracorporeal lithotripsy for the treatment of urolithiasis in children. J. Pediatr. (Rio J.) [online]. 2002, vol.78, n.5, pp.367-370. ISSN 0021-7557.

Objective: urolithiasis affects between five and 10% of the human population during their lifetime, only 2-3% of whom are children. Therapy of urolithiasis 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 urolithiasis 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. Conclusions: extracorporeal shockwave lithotripsy is a safe and effective treatment for pelvic, caliceal, ureteral and bladder urolithiasis in children. Staghorn calculi have not shown satisfactory results when treated by this method. Extracorporeal shockwave lithotripsy results were influenced in our experience by the position and size of the treated calculi.
