Purpose:
To report the cases of urolithiasis in children and to assess epidemiological, clinical and therapeutically aspects.
Patients And Methods:
We study retrospectively the cases of urolithiasis in children of 0 to 15 years old between 2003 and 2008. The parameters of study were: age, sex, clinical and therapeutically aspects.
Results:
We report 20 cases. The mean age was 5.4 years. The sex-ratio was 9/1. Dysuria was the most common symptom. Abdominal plain radiography associate with ultrasonography permitted the diagnostic in most cases. Stone location was in the bladder mainly (n = 12). Posterior Urethra valves were the common etiology found. The surgical treatment was performed in all cases and consisted of cystolithotomy in the majority.
Conclusion:
Children urinary stones are less common than in adults. The etiologies are different but the treatment is coming to be alike.
