Extracorporeal Shock Wave Lithotripsy for 57 Cases of Pediatric Urinary Stone with EDAP LT-01+ and Storz Modulith SLX Lithotriptors / 대한비뇨기과학회지

ABSTRACT

PURPOSE: Reports of clinical findings and treatment for pediatric urinary stone have been published relatively infrequently. Extracorporeal shock-wave lithotripsy (SWL) is a minimally invasive method of treating urinary stone and has been shown to be effective in the pediatric population. We evaluated the clinical characteristics of patients with pediatric urinary stone and compared the therapeutic results of two SWLs, LT-01+ and Modulith SLX lithotriptors. MATERIALS AND METHODS: The records of 57 children treated by SWL were analyzed retrospectively. Twenty-five patients were treated by LT-01+ (group I) and 32 by Modulith SLX (group II) lithotriptor. The outcomes, including the number of treatment sessions, stone free rate and complications, were assessed. RESULTS: The average age of all 57 children, 36 male and 21 female, was 14.3 years. Chief complaints were flank pain (71.9%), gross hematuria (10.5%) and urinary tract infection (12.3%). The average stone size was 8.2mm (2-15mm). The success rates of each SWL were similar in both groups (group I 88.0%, group II 90.6%). However the average number of treatment sessions/patient in Group I was significantly smaller than that of Group II (group I 2.92, group II 1.35, p<0.05). Flank pain and gross hematuria were developed similarly after treatment in both groups, and needed only conservative therapy and was resolved within three days. CONCLUSIONS: Clinical characteristics of urinary stone in children were similar to those of adults. There was no significant difference in treatment success rate between the two types of lithotriptors but the number of treatment sessions was smaller in patients treated by Modulith SLX lithotriptor.
