Abstract

OBJECTIVE: To 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 METHODS: From 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.

RESULTS: The 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.

CONCLUSION: The results of ESWL for inferior caliceal calculi ≤20 mm in adults remain 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.

I agree to the author's conclusion: "ESWL can be considered as the first treatment alternative in the management of lower calyx stones ≤20 mm in children."
