Factors Influencing the Success of Shock Wave Lithotripsy Treatment for Urinary System Stone Disease in Children Aged 0-2

Abstract

Objective:Factors that may influence the efficiency and reliability of shock wave lithotripsy have been examined in the treatment of stone disease in patients aged 0-2.Materials and Methods:The data of 149 patients treated with shock wave lithotripsy in our clinic between the ages of 0 and 2 years were evaluated retrospectively. Factors for predicting success in terms of overall stone-free rate were analyzed using univariate and multivariate analyses.Results:The mean age of the group was 14.39±4.56 months. The stone-free status was achieved in 102 (70.5%) patients in the first session, 15 (65.2%) of 23 patients in the second session, and 2 (50%) of 4 patients in the third session. Thus, 122 (81.9%) of the children were stone-free after shock wave lithotripsy at an average of 10.01±11.34 months of follow-up. The mean stone size was 8.66±3.47 mm. Moreover, smaller stone size and single stones were found to be significant predictors of treatment success (p=0.007 and p≤0.001, respectively). Additionally, it was determined that the single number of stones had a positive effect on treatment success in multivariable analysis (area under the curve=0.683, p=0.002). There were no major complications observed.Conclusion:Our study has shown that shock wave lithotripsy can be used with high success and low morbidity in the treatment of urinary system stone disease in children aged 0-2, especially in the presence of a single stone.
