The construction of guidelines for management of renal stone disease is complicated by several issues. First, diagnosis is critical to good management, but levels of evidence have not been described for diagnostic tests particularly when there is no comparative test of 100% sensitivity and specificity. Second, the disease is managed by a variety of specialties, mainly urology, and hence nephrol...

OBJECTIVES Many patients present with bilateral stones. There is a unique group of patients, however, that presents with stones exclusively on one side. We hypothesize that in such situations, 24-hour urine collections may not reveal specific defects on the affected stone-bearing kidney. We therefore evaluated selective 12-hour urine collections after percutaneous nephrolithotomy (PNL) to help ...

introduction the concentration of substances, including urea, creatinine, and uric acid, can be used as an index to measure toxic uremic solutes in the blood during dialysis and interdialytic intervals. the on-line monitoring of toxin concentration allows for the clearance measurement of some low-molecular-weight solutes at any time during hemodialysis.the aim of this study was to determine the...

BACKGROUND Studies that evaluate the effect of age and gender on the stone composition are scarce. The aim of this study is to highlight the modification of epidemiological characteristics of this pathology according to patients' sex and age. PATIENTS AND METHODS We studied 1269 urolithiasic patients ranging from 6 months to 92 years old and known as having urinary stones (752 males and 517 f...

BACKGROUND IRCU is traditionally considered as life?style disease (associations with, among others, overweight, obesity, hypertension, type-2 diabetes), arising from excess, in 24 h urine, of calcium (Ca) salts (calcium oxalate (CaOx), calcium phosphate (CaPi)), supersaturation of, and crystallization in, tubular fluid and urine, causing crystal-induced epithelial cell damage, proteinuria, crys...

A variety of factors influence the formation of calcium oxalate kidney stones, including gender, diet, and urinary excretion of calcium, oxalate, and uric acid. Several of these factors may be related to body size. Because men on average have a larger body size and a threefold higher lifetime risk of stone formation than women, body size may be an important risk factor for calcium oxalate stone...

background: the role of attenuation in antioxidant capacity or expansion of pro-oxidant/oxidant is well known for the development of stress oxidative. the aim of this study was to evaluate the plasma antioxidant capacity along with uric acid in patients with diabetic nephropathy (dn+) and without diabetic nephropathy (dn-). materials and methods: the research population included 88 patients wit...

coronary artery disease (cad) and vascular insufficiency are consequences of modern lifestyle, and vasogenic erectile dysfunction (ed) is one of the leading causes of sexual dysfunction which could be prevented like ischemic heart disease if the risk factors are discovered and managed. seventy-five men scheduled for coronary angiography were asked to fill out the iief5 questionnaire and underwe...

background: common carotid intima-media thickness (cc-imt) measured by ultrasonography as a non-invasive method is nowadays known as a marker for early atherosclerosis. objectives: survey the relationship between serum uric acid and carotid intima-media thickness considering hypertension. materials and methods: this study was designed as a comparative cross-sectional study in northern iran in 2...
