title: [Long-term evaluation with DMSA-Tc 99m scintigraphy of renal parenchymal involvement in children after shockwave extracorporeal lithotripsy].
abstract: OBJECTIVE
  This study evaluated the long-term effects of extra-corporeal shock-wave lithotripsy (ESWL) on the renal parenchyma of children using DMSA-Tc 99m scintigraphy.
  
  
  METHODS
  Between November 1989 and April 1997, twenty-three children wee treated for renal stones using a SONOLITH 3000 lithotriptor (Technomed-Corp. Evaluation of treatment and its consequences was based on clinical examination, conventional imaging and comparison with DMSA-TC 99m renal scintigraphy performed the day before and at least 6 months after treatment.
  
  
  RESULTS
  The success rate (fragmented and eliminated stones) was 90% at 6 months. Long-term follow-up did not reveal any alteration of blood pressure or renal function. Scintigraphic examinations did not demonstrate any significant parenchymal lesions attributable to treatment.
  
  
  CONCLUSIONS
  Extracorporeal shock wave lithotripsy is effective in adults and young children. Its safety on the renal parenchyma was demonstrated during this study. However, evaluation of larger series with the use of other lithotriptors is necessary before reaching any definitive conclusions.
