In patients with uncomplicated idiopathic hypercalciuria renal function is normal except for increased renal calcium excretion. In this study, the level of fractional urinary enzyme excretion was assessed in relation to calciuria. Fourteen patients with a mean age of 5.8 ± 0.8 years who had daily urinary calcium excretion more than 4 mg/kg and with otherwise normal renal function tests were included in the study. None of the patients manifested either renal calculus or nephrocalcinosis. Fourteen normal children with a mean age of 5.4 ± 0.74 were included in the control group. The level of the urinary N-acetyl β-D glucosaminidase (NAG) to creatinine ratio, fractional aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) excretion were not significantly different compared to the control group (p > 0.05). The patients were subdivided according to the type of hypercalciuria. The levels of N'AG/creatinine ratio, fractional ALT, AST, ALP, LDH excretion were not significantly different in the absorptive type of caiciuria group compared to the control group (p > 0.05). In conclusion, hypercalciuria during childhood which is 6.46 ± 1.83 mg/kg/day is not related to the levels of NAG/creatinine ratio, fractional ALT, AST, ALP and LDH excretion in urine.
