ObjectiveTo retrospectively evaluate the effectiveness of extracorporeal shock wave lithotripsy (ESWL) for inferior caliceal calculi ≤20 mm in size and compare the results between children and adults.Materials and MethodsFrom January 2004 to January 2012, ESWL was performed for inferior caliceal calculi in 230 children and 1006 adults. The Dornier compact alpha-K1025163 (Dornier Med Tech) was used. The success rates, number of ESWL sessions required, and auxiliary procedures used were evaluated in a comparative manner.ResultsThe overall stone-free rate (for both stone sizes) was 82.2% for children and 40% for the adults. Of the children, 17% had a residual stone compared with 47.8% of the adults. ESWL was unsuccessful in 0.8% of children and 12.2% of adults. The mean number of ESWL sessions required in children and adults was 1.43 (range 1-4) and 2.13 (range 1-4), respectively. Repeat treatment was required in 31% of the children and 65% of the adults. Auxiliary procedures were required in 5.2% of the children and 16.2% of the adults. Complications were seen in 5.6% of the children and 15% of the adults.ConclusionThe results of ESWL for inferior caliceal calculi ≤20 mm in adults remains poor but not so in children. Children can achieve high stone-free rates, require a fewer number of ESWL sessions than adults to be stone free, and have a lower need for repeat treatment and auxiliary procedures, and have fewer complications.
