Urolithiasis constitutes a worldwide health problem with a frequency of up to 15% in the general population. The causes are diverse; exogenous influences and genetic factors act in complex interaction and thereby impede research on stone formation. In recent years, important advances on the elucidation of molecular and genetic bases have been made. Numerous genes for urolithiasis and syndromes ...

Initiation and Growth of Uroliths Urolith formation, dissolution, and prevention involve complex physical processes. Major factors include: 1) supersaturation resulting in crystal formation, 2) effects of inhibitors of crystallization and inhibitors of crystal aggregation and growth, 3) crystalloid complexors, 4) effects of promoters of crystal aggregation and growth, and 5) effects of non-crys...

Introduction Urinary stones are relatively uncommon in the paediatric age group; however, the prevalence seems to be on the increase and the tendency towards urinary lithiasis in males and females is the same in childhood.1,2 The clinical features are often vague and nonspecific, so a high index of suspicion is usually required for diagnosis. Limited investigations tend to be performed in child...

a study was designed to evaluate the normal value of 24 hr urinary calcium levels in the city of yazd. the average urinary excretion of calcium in a sample of 329 persons randomly selected was 232 mg/day, while patients with a history of recurrent urolithiasis excreted 20x mg/day. there is evidence which shows that more important factors than the amount of urinary calcium exist which influence ...

A retrospective review was performed of the records of 148 Croatian children with urolithiasis treated between 1989 and 2003. The study evaluated age, gender, family history, clinical symptoms, location of stone, laboratory findings, stone composition, mode of treatment and compared our results with data from higher and lower socio-economic countries. The mean age of our patients was 9.38 years...

OBJECTIVES A project was initiated by the Health Care Office of the European Association of Urology in order to formulate common recommendations and guidelines for the treatment of patients with urolithiasis. The basic task for the working group therefore was to extract and evaluate evidence from the literature in order to reach a consensus on how these patients could best be managed. METHODS...
