Chemical analysis of urinary calculi in children

A study of 23 cases of urinary calculi, that were chemically analyzed, showed that most common constituent of the stones removed was oxalate followed by urate. Struvite stones were found infrequently. The lower urinary tract stones occurred more frequently than upper tract calculi and all urates calculi were found in patients less than five years of age. These findings differ from those reported from other developing countries
