Introduction: This study assesses the differences in the presentations, complications and metabolic abnormalities of children with renal calyceal microlithiasis (RCM) and overt urolithiasis in different pediatric ages. Materials and Methods: A total of 465 children with urolithiasis were investigated retrospectively. Patients were categorized based on their ages to infancy, early childhood, middle childhood and adolescence. When the hyperechogenic spots on ultrasound imaging were <3 mm, they were considered RCM, and if they were ≥3 mm, they were considered overt urolithiasis. Results: Metabolic abnormalities were detected in 71%; hyperuricosuria in infants, hyperoxaluria in younger children and hypocitraturia in older children were the most common metabolic abnormalities. Hypercalciuria was the only metabolic abnormality that was significantly associated with overt urolithiasis in all pediatric ages (OR 2.25, 95% CI 1.21-4.19). The clinical presentations were not significantly different between RCM and overt urolithiasis; however, complications such as urinary tract infection was significantly higher with overt urolithiasis in infancy (p = 0.01), early childhood (p = 0.02), middle childhood (p = 0.007) and adolescence (p = 0.01). Also, growth retardation was significantly higher with overt urolithiasis in infancy and early childhood (p = 0.02). Conclusions: Most children with urolithiasis have underlying urinary metabolic abnormalities that differ according to the child's age. Despite these differences, hypercalciuria is significantly associated with overt urolithiasis in all pediatric ages. Clinical and laboratory features cannot differentiate RCM and overt urolithiasis; however, complications are significantly higher with overt urolithiasis.

“…Nevertheless, the pathogenesis of calcium oxalate stones, which account for >80% of all types of stones, still remains controversial [4]. It is suggested that both environmental and genetic factors play important roles in the development of urolithiasis [5,6]. Alterations in dietary habits are considered to have contributed remarkably to the increasing risk of urolithiasis in the past decades [7].…”

Objective: We conducted a meta-analysis to quantitatively evaluate the correlation between alcohol consumption and the risk of urolithiasis by summarizing the results of published case-control and cohort studies and the potential dose-response association. Methods: A systematic literature search of articles up to February 2014 was conducted via PubMed, Web of Science, Cochrane Library, Scopus, EMBASE, the Chinese National Knowledge Infrastructure databases, and the references of the retrieved articles. Fixed- or random-effect models were used to summarize the estimates of odds ratio (OR) with 95% confidence interval (95% CI) for the highest versus the lowest consumption of alcohol. A dose-response meta-analysis was also conducted. Results: The pooled OR estimates indicated that alcohol consumption was associated with a decreased risk of urolithiasis (OR = 0.683, 95% CI 0.577-0.808). In addition, the dose-response meta-analysis indicated that the rate of urolithiasis decreased by 10% for a 10 g/day increase in alcohol intake (OR = 0.898, 95% CI 0.851-0.948). No evidence of publication bias was found by Begg's or Egger's test (p = 0.130, p = 0.130, respectively). Conclusion: Our meta-analysis indicated that alcohol intake is associated with a decreased risk of urolithiasis.

Background: The incidence of urinary tract calculi is thought to be higher in patients with inflammatory bowel disease (IBD) than that in the general population. However, few data are available about urolithiasis in patients with Crohn's disease (CD). We investigated the incidence of urolithiasis and the risk factors for urolithiasis in patients with CD. Methods: We examined the records of 387 patients with CD followed at Samsung Medical Center from July 2011 to June 2013. Evidence for the presence of calculi was obtained from radiologic findings (plain films, ultrasonography, or computed tomography), urinary colic symptoms, or a treatment history of urolithiasis after diagnosis of CD. Demographic variables, phenotype, concurrent medications, and previous CD-related surgery were analyzed. Results: Urinary tract calculi were found in 18 (4.7%) patients, which developed after the CD diagnosis. The incidence of urolithiasis in CD was 706 per 100,000 patient-years. Cox models with a time-dependent covariate showed that azathioprine (AZA)/6-mercaptopurine (6-MP) treatment (hazard ratio = 0.963; 95% CI: 0.931, 0.996; p = 0.030) was negatively associated with urolithiasis. Conclusions: The annual incidence rate of urolithiasis in patients with CD was 0.7%. AZA/6-MP therapy was associated with a low risk of urolithiasis in these patients.
