A prospective study was conducted to determine the frequency and clinical characteristics of childhood idiopathic hypercalciuria, especially in the group of children with primary hematuria. Baseline study group consisted of 83 children with minor illnesses who were admitted to the pediatric department from July to September 1988. And hematuric study group consisted of 25 children with recurrent gross or persistent micros- copic hematuria of unknown etiology for the duration of 1 year from July 1987 to JuJy 1988. The following results were obtained. From 83 baseline study group, 5 cases (6.3%) were found to have idiopathic hypercalciuria, showing uri- nary calcium excretion over 4 mgjkg/day. Out of 25 hematuric group, 6 cases (24%) were diagnosed as idiopathic hypercalciuria and oral calcium loading test showed absorptive type in 4 and renal type in 2. One child showed renal stone. Oral hydrochlorothi- azide administration resulted in prompt cessation of hematuria in 3 cases (1 absorptive and 2 renal cases) In summary, present study demonstrates that idiopathic hyperciuria is a major cause of primary hematuria in children and in these children, clnse follow : up should be done, especially in regard to renal stone formation. |
