Children with complex medical conditions pose many difficulties in the evaluation
and prevention of their nephrolithiasis episodes. DeFoor et al. present the next logical
step in understanding the etiology of urinary stone disease in these children. The
authors investigated the 24-h urine analyses of children with complex chronic conditions,
many of whom depend upon enteral nutrition, and compared these to an unmatched cohort
of otherwise healthy children with nephrolithiasis. While such an analysis is limited
due to the retrospective and uncontrolled nature of the assessments, the difficulty
in obtaining urine samples in such a population makes this study a valuable manuscript
for future reference. Interestingly, as opposed to common hypotheses related to calcium
metabolism in the chronically immobilized, the authors found a significantly higher
concentration of urinary oxalate in the study population. Several possibilities could
exist to explain these differences. Oxalate is known to vary more substantially in
younger populations and perhaps repeat 24-h studies would yield different results
[
[1]
]. However, supposing these findings represent true and meaningful differences in
urinary oxalate, a consideration of oxalate metabolism is warranted.To read this article in full you will need to make a payment
