title: Urinary calculous disease in childhood.
abstract: Reviewed are 56 cases of children suffering from urinary calculous disease between 1970 and 1977; 27 were female and 29 male. The age distribution was from one month to fourteen years. In 34 per cent of the children urodynamic disorders were responsible for stone formation, 23 per cent had identifiable metabolic disorders, and in 43 per cent the cause of stone formation was unknown. Urinary infection was present in 60 per cent of the patients. Forty-five of the 56 children (80 per cent) had to undergo surgery. After surgery 78 per cent remained stone free, while 16 per cent had recurrent stones, only half requiring a second operation. In cases of active stone disease, especially in the group with underlying metabolic disorders, specific therapeutic measures have been applied and the patients regularly investigated afterward.
