Abstract

Hyperoxaluria is defined as urinary oxalate excretion exceeding 0.45 mmol/1.73 m2/day and accounts for 15% of recurrent urolithiasis. There have been only a few reports on the prevalence and treatment of oxalate urolithiasis in children.

THE AIM:

Of the study was to assess the efficacy and safety of the protocol of intensive and combined treatment of hyperoxaluria in children.

MATERIAL AND METHODS:

Seventeen children at the mean age of 11.5 +/- 4.5 years with positive history of urolithiasis and diagnosis of hyperoxaluria were studied. In this group hyperoxaluria was an isolated defect in 9 of 17 children, but in 3/17 it was accompanied by hyperuricosuria, in 5/17 by hypomagnesuria and in 1 case by hypercalciuria. During the 12-month period the children were intensively hydrated and received a low-oxalate diet and supplemental therapy with vitamin B6, magnesium, citrates and lactic acid bacteria preparations.

RESULTS:

In all but one child oxaluria decreased below 0.45 mmol/1.73 m2/day (decrease by 45%). No new stone formation was seen during the observation period. In all patients abdominal pain and haematuria subsided.

CONCLUSIONS:

We conclude that the intensive, complex, conservative treatment of hyperoxaluria in children is effective and safe. It allows to decrease hyperoxaluria and prevent the recurrence of urolithiasis.
