Who should have 24 hour urine chemistries measured as part of their evaluation?
Adults with recurrent stone disease should have 24-hour urine chemistries measured.
Some adults with a single stone event will require full evaluation as dictated by their career, such as airline pilots. Recent AUA guidelines suggest performing 24-hour urine studies in first-time stone formers if they are highly motivated to prevent future stones.
In addition, all children with kidney stones should have urine chemistries performed, because they have a higher likelihood of having a severe inherited form of nephrolithiasis such as cystinuria or primary hyperoxaluria.
