ABSTRACT
A total of 17 children with 24 renoureteral units underwent 58 treatment with EDAP LT-01 extracorporeal shock wave lithotripsy for urinary tract stones between January 4, 1989 and January 30, 1993. The patients were followed for over two months. The results were obtained as follows ; 1. The distribution of sex was 9(53%) in male and 8(47%) in female. The average patient age was 7 years with a range of 6 months to 16 years. 2. The location of stones were kidney in l8 cases( 75.0%) ; calyx in 10 (41.7% ) and renal pelvis in 8(33.3% ) and ureter in 6(25.0%) ; upper ureter in 2(8.3%) and lower ureter in 4( 16.7%). There were multiple renal stone in 4 and bilateral renal stone in 2. The average stone length was 9mm with a range of 3 to 10mm. 3. Of the 13 patients whose age was less than 10 years, 11(84.6%) required intravenous Ketamine anesthesia. Two patients whose age was more than 10 years and two patients less than 10 years were treated without any type of anesthesia. 4. The average numbers of treatment were 2.1 session and the average storage required was 19.4 in one session The average treatment time was 39.7 minutes. 5. The total average success rate was 87.5% 6. All of the patients were not the pre- and post- ESWL additional manipulation. ESWL complications did not require admission and surgical management. Therefore, we conclude that EDAP LT-01 is an effective and easy procedure for treatment of urinary stones in children.
