Introduction. Urolithiasis is not a very frequent condition in the pediatric patients. According from epidemiologic and geographic variation, the general prevalence is from 1 to 3% of all urinary stones, with significant incidence in developed countries. Material and Methods. Retrospective data of pediatric urolithiasis patients who underwent ESWL between 2011 to 2022 were used in this retrospective observational study. Extracorporeal shock wave lithotripsy was done for 32 patients. The total number of 43 ESWL sessions were recorded. Radiologic and ultrasound was used to focalized and locate the stones during the ESWL session. This required the pediatric patient to be exposed to the least amount of radiation possible. For X-ray positive stones, X-ray monitoring was used. All patients underwent Extracorporeal Shock Wave Lithotripsy (ESWL) treatment using the second generation Storz Modulith SLK device. Results. The mean overall treatment was 1.1 ± 0.4 sessions with mean stone length of 9.3 ± 6.3 mm of stone. The stone free rate after 2 sessions of ESWL was 94,5%. Complications included - urinary tract infections, kidney pain and abdominal pain. Severe complications such as hematoma, were not observed. The majority of complications observed were associated with urinary tract obstruction caused by stone fragments (“steinstrasse”). Conclusion. Extracorporeal shock wave lithotripsy has been shown to be a safe and successful minimally invasive therapy for kids with kidney stones in pediatric population.
