Objective
To evaluate the natural course of the stone disease in pediatric patients from different perspectives among which the spontaneous passage and stone recurrence rates evaluated during the follow-up.
Materials and methods
A total of 142 children referring with primary urinary stone disease were evaluated and followed. All children in the study were divided into two groups with respect to the age (Group 1: 0–5 years and Group 2: 6–15 years). Children were followed with respect to spontaneous passage rates, recurrence-regrowth rates, physical as well as the renal growth rates.
Results
Stone recurrence has been noted in 44% of patients in group 1, this value was 31% in group 2. Children with at least one identifiable metabolic abnormality tended to have higher recurrence rates than the others despite conservative measures. The average stone recurrence rate in children without any metabolic abnormality was 14% and nearly 50% in children with an identifiable metabolic abnormality.
Conclusions
We may emphasize that due to the high recurrence and re-growth rates, all children with urinary stone disease should be followed closely with regular visits. The evaluation of metabolic risk factors in children with renal stone disease is the basis of medical treatment aimed at preventing recurrent stone events and the growth of pre-existing calculi.
