“…19 During the ®rst year post injury, when immobilization hypercalciuria is a concern, an increased risk of kidney stones in men, Caucasians, and people between 40 and 60 years of age is consistent with ®ndings in the general population, 15,16,20 where calcium stones are predominant. 21 The dierential urinary excretion of calcium as a result of variation in hormones (such as testosterone) with age and gender has been hypothesized to account for the observed risk dierence in the general population. The potential in¯uence of these demographic factors on mineral metabolism during the acute phase of injury might explain the variation in stone risk, which needs further con®rmation.…”

Current trend and risk factors for kidney stones in persons with spinal cord injury: a longitudinal study

Study design: A multi-center longitudinal study. Objectives: To estimate the current trend in the incidence of ®rst kidney stone among persons with spinal cord injury (SCI) and to delineate the potential contributing factors. Setting: Twenty-one Model SCI Care Systems throughout the United States. Methods: A longitudinal cohort of 8314 subjects enrolled in the National SCI Database between 1986 and 1999 was used to estimate and compare the incidence of ®rst kidney stone with a previous report of 5850 SCI patients injured between 1973 and1982. A Cox regression analysis was performed to identify risk factors for stones, including age, race, gender, severity of injury, and method of urinary drainage. These variables have been routinely collected, on a yearly basis, by the collaborating SCI centers. Results: During the 12 years, 6 months of case ascertainment, 286 incident stone cases were documented. The risk was greatest during the ®rst 3 months after injury (31 cases per 1000 person-years), quickly decreasing and leveling o later (eight cases per 1000 person-years). It was estimated that within 10 years after injury, 7% of persons with SCI would develop their ®rst kidney stone. There was no evidence that the risk has changed over the past 25 years (P=0.96). During the ®rst year post injury only, a signi®cantly increased risk of stones was observed in Caucasians and persons aged 45 years or older. A positive association of the severity of injury and requiring instrumentation for bladder emptying with kidney stones was found after the ®rst year post injury. The type of urinary drainage, including indwelling, intermittent, and condom catheterization, had no signi®cant dierential eect on stone formation at either risk period. Conclusions: The highest risk of kidney stones is within the ®rst few months post injury. Little progress has been made in reducing this risk. Although inability to control bladder function is an important risk factor after the ®rst year post injury, for those who need bladder management, the type of urinary drainage does not appear to be an important factor in determining risk.

“…There are many factors related to the onset of UC; however, no precise etiology has been confirmed yet (Siener, 2006). Various domestic and international studies have confirmed that the etiology of UC is closely related to environmental factors (Finlayson, 1974;Embon et al, 1990;Leusmann et al, 1990), as well as to genetic factors, ethnicity, gender, age, dietary habits, urinary biochemical abnormalities, etc. (Siener, 2006;Park et al, 2010;Kirejczyk et al, 2014).…”

ABSTRACT. The incidence of urinary calculus (UC) is very high in Uyghur children in the Kashi region of Xinjiang, China, which seriously affects the growth and life quality of these children. This study was aimed at investigating the risk factors of UC in Uyghur children in Kashi region. One hundred fifteen Uyghur children (age <7 years) with UC who were treated in First People's Hospital in Kashi were enrolled in the case group. A 1:1 case-control study with a questionnaire was performed. The results showed that, among the 115 UC patients, there were more boys (71.3%) than girls (28.7%), and most cases had an onset age of 1-3 years (75.7%). A lower than primary school education in the mother, drinking unboiled water, water intake <500 mL/day, and eating too much sweets were risk factors [odds ratio (OR) = 2.385, 9.160, 3.263, and 8.945, respectively], whereas vegetable intake and exposure to summer sunshine of <2 h/day were protective factors against UC onset (OR = 0.154 and 0.344, respectively). Analysis of UC-related factors in 99 cases of <3-year-old children revealed that breastfeeding was also a protective factor (OR = 0.007), whereas frequent cow's milk intake within 5 months (OR = 2.414) and frequent "panada" intake (OR = 2.529) were risk factors. The occurrence of UC in Uyghur children in the Kashi region is mainly affected by maternal educational background, quality of drinking water, water intake volume, and dietary pattern. Furthermore, geography may also have a role.

“…The risk of stone disease depends on various environmental factors (climatic changes, geographical locations, dietary habits, and obesity) and as well as genetic factors (sex, age, race, idiopathic hypercalciuria, hyperoxaluria, and hyperuricosuria) (4) According to the literature, about 25% of patients with urolithiasis have a family history of stone disease and the relative risk of stone formation is higher in men with a family history than in women those without a family history. (5, 6) Family history positivity has been subjected to a number of studies in recent years (11,12) The aim of this study is to examine the influence of family history and to find the recurrence rate on urinary stone disease in Sri Lanka.…”

Abstract-Urinary calculi disease is one of the most common urological disorders. The descriptive cross sectional study was conducted to examine the influence of family history and to find the stone recurrence rate on urinary stone disease in Sri Lanka. The sample size of the study population was 142 with the mean age of 44.65± 13.45 years. They were evaluated with respect to their past history and family history of the disease. According to the results 58% of subjects were without past history, 42% of them were with past history and 85% of subjects without family history, 15% of them were with family history. Although pathophysiology of urolithiasis, is multifactorial a positive family history may also affect the occurrence and the cause of urinary stone disease. In our study familial urolithiasis was observed in 15% of patients which is lower than world literature. This is a significant finding Sri Lanka being an island nation.
