title: [Renal calculi in an infant].
abstract: Urinary concretions, particularly in the upper urinary tract, occur in otherwise healthy children in connection with Bacillus Proteus urinary infections. In other European countries, this occurs in 40-70% while, on the other hand, it is particularly rare in Scandinavia. A case of obstructing pelvic concretion in a boy aged three months is presented. This is the youngest case which could be found in the literature. Pyelolithotomy was performed and the child has been free from recurrence for six years. At the commencement of the disease, pain due to renal calculi may be misinterpreted as being due to three-months intestinal colic. Formation of calculi is presumed to be due the ability of Bacillus Proteus to form urease. The frequency of recurrences is 3-8% and is lowest if the urine can be maintained sterile for the first three months after removal of the stone.
