Abstract

Between February 8, 1990 and August 31, 1992, 12 renal units in 11 pediatric patients were treated by extracorporeal shock wave lithotripsy(ESWL) with the EDAP LT-01 + lithotriptor.The results were obtained as follows: 1. The sex ratio was 1.2:1, and the average patient age was 8.5 years with a range of 16 months to 15 years. 2. The locations of stones were renal without staghorn calculi in 1 renal units (33.3%), staghorn calculi in 2 (16.7%). upper ureter in 2(16.7%) and lower ureter in 4 renal units(33.3%). The average stone size was 16.8 mm with a range or 5 mm to 50 mm. 3. The factors predisposing to stone formation were urinary tract infection in 4 patients (36.4%), hypercalciuria in 1 (9.1%), hypoplastic kidney in 1 (9.1%), incomplete duplicated ureter in 1 (9.1%) and unknown factor in 4 (36.4%). 4. Or the 11 patients, 2 patients required I.V. anesthesia, 1 patient required epidural anesthesia and 8 patients were treated without any type of anesthesia. 5. The average number of treatment were 5.1 sessions and average storage required was 22.2 in one session. The average treatment time was 43 minutes. 6. The success rate of treatment-ended 11 renal units (complete removal of stones) were 90.9% 7. Comparing the results of ESWL in the treatment of urolithiasis in adult and children, the average storage of treatment was almost equal in both groups, but the time and numbers of treatment required in children was greater. Therefore, we conclude that extracorporeal shock wave lithotripsy with EDAP LT-01 + lithotryplor is considered to be a safe and effective procedure for treatment of urinary stones in child.
