Kidney stones: Composition, frequency and relation to metabolic diagnosis.

Nephrolithiasis is one of the most frequent urologic diseases. The aim of this paper is to study the composition and frequency of 8854 patient kidney stones and in a subset of them their metabolic risk factors to be related to their type of calculi. Physicochemical and crystallographic methods were used to assess kidney stone composition.

Metabolic risk factors in children with asymptomatic hematuria.

Background: Idiopathic or benign hematuria is diagnosed in children after all other possible causes have been ruled out and test results for renal or urologic pathologies are negative.

Methods: To identify possible urinary risk factors for hematuria in children, we retrospectively evaluated clinical onset, family history, and metabolic risk factors of 60 children with idiopathic hematuria but without renal stones or other pathologic conditions that could explain the hematuria. All patients followed the same ambulatory protocol at that used to evaluate kidney stone-formers.
