OBJECTIVES: Management of ureteral stones in children represents a challenging problem. In this study, we retrospectively analyzed our experience with extracorporeal shock wave lithotripsy (ESWL) in 192 children with ureteric stones. METHODS: Between 1990 and 2003, 192 children (<or= 14 years old) with ureteric calculi were treated with the Siemens Lithostar Plus (Siemens Medical Systems, Iselin, NJ). There were 39 stones in the proximal ureter, 19 in the mid-ureter and 134 in the distal ureter. RESULTS: Mean patient age was 7.3+/-4.1 years (6 months-14 years). There were 122 boys (64.2%) and 70 girls (35.8%). All procedures were performed on an outpatient basis with intravenous sedation in 73 cases (38.1%), general anesthesia in 68 cases (35.7%) and no anesthesia in 51 cases (26.2%). A maximum of 3500 shocks and 18 kV per session were used. A 94% success rate was achieved in proximal (n: 39) and mid-ureteral stones (n: 19). Stone free rates for distal ureteral calculi were 90.6% for stones less than 1 cm in diameter (n: 94) and 91.7% for stones between 1 and 2 cm (n: 26). Overall re-treatment and efficacy quotient rates for proximal ureteral stones were 45.1% and 68.9%, 62.5% and 61.5% for mid-ureteral calculi, and 49.6% and 60.0% for distal ureteral stones. CONCLUSION: Our results indicate that ESWL with highly satisfactory stone free rates ranging between 90 and 100% and negligible complications can be considered as a first line treatment for ureteric stones in the pediatric age group.
