[Today's prognosis of urolithiasis caused by infection calculi in the young child].
In 24 infants (age 1-4 years) with urolithiasis a good and recurrence-free long-term prognosis is shown in 15 patients with infected stones under following conditions: early diagnosis and operative treatment without residual stones, immediate therapy of bacteriuria and close-meshed follow-up controls. In these 15 infants the morbidity peak was in the second year of life. However in the remaining 9 infants with calcium oxalate calculi recurrent stones did occur on an average of 6 years despite of non-infection. The incidence of urolithiasis in the first to sixth year of life was 1:5 in comparison with the school age.
