Piezo-electric lithotripter in the treatment of pediatric renal calculi.
EDAP LT-01 lithotripter was used to treat 23 stone events in 17 pediatric patients. The mean age of the patients at treatment was 7.2 years, the youngest being 18 months. The mean stone size was 1.22 cm. Thirty-six sessions of extra corporeal shock wave lithotripsy (ESWL) treatment were necessary for the 23 stones. The focal point pressure power was 60-100% (540-900 Bar), the treating period 0.5-1 hour and the frequency 1.25-2.5 Hz. The patients were stone free in 2 months. IVU or ultrasonography showed that there was no renal dysfunction and retardation of renal growth after ESWL. Appropriate ESWL monotherapy in pediatric patients may produce results comparable to those in adults. Factors known to affect treatment results in adults also influence the results in children and should be considered in terms of the applicability of ESWL to any particular pediatric patient.
