title: [Urinary calculi in children (author's transl)].
abstract: From a total of 274 children with urinary calculi, 192 cases were analyzed. 63% of these were male. In 19% a familiar disposition was noticed. Phosphate containing stones were found in 81%. Most of these had an urinary tract infection caused by urea splitting organisms. There was no correlation between the chemical composition of the stones and infection with coli and enterococci. One-third of the analyzed cases exhibited malformations of the urinary tract. Of these, 92% had urinary infections due primarily to urea splitting bacteria. This infection rate was markedly higher than in the children without combined malformations of the urinary tract. The peak incidence was around 2 years of age. In the last group symptoms were atypical but more severe than in those cases without malformations of the urinary tract.
