Answer

Initial stones in elderly people and in children are relatively uncommon; however, consider kidney stones whenever acute back or flank pain is encountered, regardless of patient age. When stones occur in persons in these uncommon age groups, a metabolic workup consisting of a 24-hour urine collection and appropriate serum laboratory testing is recommended. To minimize radiation exposure, Tasian and Copelovitch recommend ultrasound as the initial imaging study in children with suspected nephrolithiasis, with noncontrast CT reserved for those in whom ultrasound is nondiagnostic and the suspicion of nephrolithiasis remains high.
