OBJECTIVE: To determine urinary @entity1792 excretion in @entity1 with @entity1790 and normal controls. DESIGN: Prospective. SETTING: Tertiary care center in New Delhi. METHODS: This study was done on 50 @entity1 , below the age of 12 years, with idiopathic urinary calculi and 150 age and weight matched controls. The @entity1 were divided into 3 groups: Group 1 (1-4 years), Group 2 (5-8 years) and Group 3 (9-12 years). Urinary @entity1792 was estimated in a 24-hour urine sample using colorimetric method. The stones removed from these @entity1 were also analysed. RESULTS: There was a preponderance of urinary stones in males; the highest incidence being in Group 1. Excretion of @entity1792 in 24-hour urine sample was significantly lower in @entity1 compared to controls, for males in all age groups and for females in Group 3. However, there was no statistically significant difference in the urinary @entity1792 value between males and females in a given age group for either controls or @entity1 . The urinary @entity1792 excretion increased with age in @entity1 and controls, but the levels in @entity1 were lower. Depending upon the constituents, four types of stones were identified, @entity78 , @entity3835 , @entity414 and @entity5706 . Nine stones had at least more than one major constituent. Hypocitraturia was detected in 43 percent cases. The incidence was 76 percent for @entity78 , 87 percent for @entity3835 , 40 percent for @entity414 stones and 50 percent for @entity5706 . CONCLUSION: This study shows that low urinary @entity1792 is associated with urinary stones in @entity1 , especially in endemic areas, in the absence of obvious etiological factors. Urinary @entity1792 excretion should be determined in all @entity1 with @entity1790 .
