Unlike adults urolithiasis in children is a rare disease. For this reason medical treatment in this age group is still a serious therapeutic challenge. The aim of the study was to analyze the results of the applied treatment in the first incidences of urinary stones disease. A group of 143 patients aged 1.5 to 17 years was enrolled in this study. Spontaneous stone passage was obtained in case of 65 patients, which amounts to 63% of patients, who received conservative treatment. 17% were qualified to the ESWL treatment, 5.6% underwent the URS procedure, and in 2.8% of patients open surgery was performed. In 29% of cases stones were left for further observation. Conservative therapy was effective in the majority of children with small urinary stones. Preferred treatment in remaining patients were minimally invasive urological procedures.
