Unusual aspects of urinary calculi in children.
Urinary calculous disease is unusual in children in the United States. During the last 5 years (1972 to 1977) we have examined and treated 35 children with urinary calculi. The predisposing factors to calculus formation have been established in 20 children. Metabolic screening, although mandatory, has proved unrewarding in the evaluation of children with urinary calculi. Obstructive uropathy, immobilization, urinary stasis and infection, previously undiagnosed urologic anomalies, steroid therapy, milk-alkali syndrome, iatrogenic disease and endemic disease have contributed to stone formation. The management of children with urinary calculi generally parallels that of adults but reflects a need for caution when performing transurethral extraction of lower ureteral calculi. Reduction in dairy product intake, fluid diuresis and frequent changes in position may provide adequate prophylaxis against urinary calculi in children who must be immobilized.
