PURPOSE: We evaluated the efficacy and safety of shock wave lithotripsy in the supine position through the greater and lesser ischiadic foramina as a path of shock wave to treat distal ureteral stones in young children.
MATERIALS AND METHODS: We treated 22 young children with distal urinary calculi using the Dornier Compact S lithotriptor between 1997 and 2007. The study population consisted of 15 boys and 7 girls 6 months to 7 years old (mean +/- SD 5.4 +/- 2.1 years). Stone size ranged from 5 to 16 mm (mean 6.8). All patients were treated in the supine position under dissociative anesthesia with ketamine. The focused shock wave targeted the stone in the distal ureter through the greater and lesser ischiadic foramina.
RESULTS: Number of shocks ranged from 600 to 3,000 (mean +/- SD 2,346.2 +/- 483.7). Energy per pulse ranged from level 4 to 5 (mean 4.5). Treatment time varied from 20 to 40 minutes (mean 31). Stone-free rate at 2 weeks after lithotripsy was 77.3%, which increased to 100% at 3 months after a single lithotripsy session. No serious side effects were observed.
CONCLUSIONS: Shock wave lithotripsy in the supine position through the greater and lesser ischiadic foramina as the path of shock wave treats distal ureteral stones in young children with an excellent success rate and few side effects.
