Abstract

A total of 14 children underwent 29 treatments with EDAP-LT01 extracorporeal shock wave lithotripsy for urinary tract stones between February, 1987 and ugust, 1988. The results were obtained as follows : 1. The sex ratio was about A 2:1, 9 (64.3%) in male and 5 (35.7%) in female patients. The average patient age was 7.1 years with a range of 2 to 16 years. 2. Treated stone locations were kidney in 8 children (57.1% ) ; calyx in 6 (42.8% ) and renal pelvis in 2 (14.3% ) and ureter in 6 (42.9% ) ; upper ureter in 2 (14.3% ) and lower ureter in 4 (28.6 %). There were multiple renal stone in 4 (28.6% ) and bilateral renal stone in 1 (7.1%), the average stone size was 1.6cm with a range of 0.7 to 3.1cm. 3. The average numbers of treatment were 1.8 sessions and the average treatment time was 38.7 minutes. The average storage required was 107 in one session. 4. Of the 11 patients whose age was less than 10 years, 10 (71.4% ) required caudal anesthesia. Three patients whose age was more than 10 years treated without any type of anesthesia. 5. The total average success rate of treatment-ended 11 patients was 81.8% in stones of 0.7-3.0cm. The cause of failed ESWL were stone component in 1 and impacted stone in 1. 6. All or the patients were not required the pre and post-ESWL additional manipulation. ESWL complications were not required admission and surgical management. Therefore, we confirmed that EDAP-LT01 ESWL is a safe, effective and easily applicable technique for treatment of urinary stones in children.
