Introduction. Several studies showed an association of overweight and obesity with calcium oxalate stone disease (CaOx). However, there are no sufficient data on the influence of body weight on the course of the disease and the recurrence rate. Patients and Methods. N = 100 consecutive stone formers
OBJECTIVE
We determined the effect of dietary fat and oxalate on fecal fat excretion and urine parameters in a rat model of Roux-en-Y gastric bypass surgery.
METHODS
Diet induced obese Sprague-Dawley® rats underwent sham surgery as controls (16), or Roux-en-Y gastric bypass surgery (19). After
Twelve patients having received an end-to-side jejunoileal bypass operation for morbid obesity 6-10 years previously were studied over three periods of 2 weeks each. The first period was used for baseline observations without any treatment. For the second period patients were randomly assigned to
Most kidney stones are composed of calcium oxalate, and minor changes in urine oxalate affect the stone risk. Obesity is a risk factor for kidney stones and a positive correlation of unknown etiology between increased body size, and elevated urinary oxalate excretion has been reported. Here, we used
OBJECTIVE
The aim of the study was to assess the influence of overweight and obesity on the risk of calcium oxalate stone formation.
METHODS
BMI, 24-hour urine, and serum parameters were evaluated in idiopathic calcium oxalate stone formers (363 men and 164 women) without medical or dietetic
Hyperoxaluria can cause kidney disease through multiple mechanisms, including tubular obstruction from calcium oxalate crystals, sterile inflammation, and tubular epithelial cell injury. Hyperoxaluria is also observed in individuals with diabetes mellitus and obesity, which are in turn Fourteen patients with jejunoileal bypass for obesity were treated for one week with a calcium supplement of 3g daily. During this period diarrhoea was significantly (P < 0.005) reduced by 23 per cent (97 per cent confidence limits: 7-46 per cent). Ten of the patients had hyperoxaluria (median value
BACKGROUND
Observational studies in obese adults have found abnormal urinary metabolic indices that predispose to nephrolithiasis. Few studies have been performed in severely obese adolescents.
OBJECTIVE
To assess urinary stone risk factors in severely obese adolescents and in those undergoing 2
The prevalence and incidence of urinary stone disease have been reported to be associated with body weight and body mass index (BMI). The aim of the study was to determine the difference in stone components among different BMI groups in patients with urolithiasis. Between Dec 2005 and Jan 2008, 907
In patients with hypercortisolism, who are frequently obese, the prevalence of elevated urinary excretion rates of the potential lithogenic factors (calcium, oxalate, and uric acid) is increased. We examined whether the 24-hour urinary excretion rates of calcium, oxalate, and uric acid are already
OBJECTIVE
To test the hypothesis that breed, age, sex, body condition, and environment are risk factors for development of calcium oxalate uroliths in dogs.
METHODS
Case-control study.
METHODS
1,074 dogs that formed calcium oxalate uroliths and 1,724 control dogs that did not have
OBJECTIVE
To give a comprehensive and focused overview on the current knowledge of the causal relations of metabolic syndrome and/or central obesity with kidney stone formation.
METHODS
Previous reports were reviewed using PubMed, with a strict focus on the keywords (single or combinations thereof):
OBJECTIVE
To examine the relationship between urinary pH and metabolic syndrome risk factors along with insulin resistance in obese adolescents, and to evaluate the relationship between other urinary stone-forming and -inhibiting markers and metabolic syndrome.
METHODS
A total of 46 obese
BACKGROUND
Yucatán ranks first in the prevalence of urinary calculi (UL), and above the national average of obesity (OB). The aim of the study was to determine whether there is an association between obesity and metabolic disorders (MD) in patients with UL.
METHODS
In a case-control design, 197
