PURPOSE It is thought that the 3 narrowest points of the ureter are the ureteropelvic junction, the point where the ureter crosses anterior to the iliac vessels and the ureterovesical junction. Textbooks describe these 3 sites as the most likely places for ureteral stones to lodge. We defined the stone position in the ureter when patients first present to(More)
OBJECTIVE To examine the relationship between serum 25-OH vitamin D and 24-hour urine calcium in patients with nephrolithiasis. METHODS A retrospective review was performed. Patients evaluated in 2 metabolic stone clinics were included for analysis. Multivariate linear regression models were adjusted for known risk factors for stone disease (age, gender,(More)
UNLABELLED Study Type--Prognosis (cohort series) Level of Evidence 2b. What's known on the subject? and What does the study add? Epidemiologic studies have shown that warmer climates are associated with increased incidence of nephrolithiasis. Many hypothesize that this is due to dehydration and lower urine volumes. The current study of stone formers reports(More)
Body mass index (BMI) has been shown to influence the outcome of various surgical procedures. The purpose of this study is to assess the relationship between BMI, gender, and the distribution of subcutaneous and perirenal fat. A retrospective review was performed for 123 patients who underwent radical or partial nephrectomy. Preoperative CT scans were(More)
OBJECTIVE To examine differences in 24-hour urine composition between recurrent and first-time stone-formers. METHODS A retrospective review of patients evaluated in 2 metabolic stone clinics was performed. Recurrent stone formation was defined as patients with a history of more than 1 stone episode and first-time stone-formers were those with a history(More)
OBJECTIVE To examine the relationship between the poverty and education levels and 24-hour urine composition in patients with nephrolithiasis because little is known about the relationship between socioeconomic status and kidney stone risk. METHODS A retrospective review was performed of patients evaluated at 2 metabolic stone clinics. The poverty level(More)
Web-based simulation environments will need to maintain a large collection of documents. Information about simulation models and results from multiple sites will need to be stored. This information should be held in a widely utilized and highly viewable format. The eXtensible Markup Language (XML) is a new standard that supports data exchange on the(More)
OBJECTIVE To examine the relationship between urine magnesium and hyperoxaluria in a cohort of patients with recurrent stone formation. METHODS A total of 311 patients with nephrolithaisis were evaluated. The patients were divided into quintiles of urine magnesium excretion, an accepted surrogate of dietary magnesium intake. Multivariate analysis was used(More)
OBJECTIVE To examine the relationship between GFR and 24-hour urine composition in patients with nephrolithiasis to understand how renal function may affect stone risk. Alterations in glomerular filtration rate (GFR) are associated with a number of physiological changes. METHODS A retrospective, institutional review board-approved review of patients from(More)
OBJECTIVES To examine the clinical outcomes and cost-effectiveness of endourologic procedures performed in the office using standard fluoroscopy and topical anesthesia. METHODS We performed a retrospective review of all patients who underwent primary ureteral stent placement, ureteral stent exchange, or ureteral catheterization with retrograde(More)
