title: [Pediatric Extracorporeal Shock Wave Lithotripsy].
abstract: BACKGROUND
  Extracorporeal Shock Wave lithotripsy (ESWL) is the cornerstone of pediatric urolitiasis management. We evaluated its efficacy and complications in a series of children.
  
  
  METHODS
  Children who were managed with ESWL between 2003 and 2012 were retrospectively reviewed. We studied etiology, clinical presentation, stonefree ratio and relevant complications. SPSS 17.0 software was used.
  
  
  RESULTS
  90 children aged 0 to 10 years (median 2.9 years) were included in the study; that accounted for 122 stones and 162 ESWL sessions. Mean follow up was 20 months. Mean stone diameter was 12.2 mm. (range 4-25). Most prevalent clinical sign was urinary infection (55.6%, 50 patients). 75.4% of the lithiasis were found in renal pelvis or calices. A mean of 1.42 ESWL sessions per stone was performed. Stonefree status was reached in 80.3% (98) of the lithiasis. This rate was higher in patients below 5 years of age (86.1% vs., 69.8%, p=0.03), and worse in staghorn calculi (66% vs. 87.2%) and cystine ones (30% vs. 84.8%, p<0.001). We observed 17 complications (10.4% among 162 sessions), 6 UTIs, 6 episodes of fever and 6 episodes of UTI associated with steinstrasse. Almost all complications were associated with bigger size, staghorn calculi and struvite.
  
  
  CONCLUSIONS
  Best results are found in younger patients and small calculi. ESWL is a safe and efficient procedure in pediatric patients.
