Background: Increased incidence of renal stone has been reported in ankylosing spondylitis (AS), but unlike some well-known renal involvements, they have not been fully studied. The aim of this study was to investigate the association of AS with urolithiasis and also the relation between urinary stone and severity markers. Methods: One hundred-sixty three AS patients were included in a cross-s...

Background: The main goal of this study is to determine the relationship between opium dependency and frequency of urolithiasis renal colics. Methods: In a cross sectional study we compared opium dependency in urolithiasis patients (case group) with non-urolithiasis patients (control group) and assessed urolithiasis related renal colics as risk factor to opium dependency prevalence. Dependency ...

PURPOSE Topiramate is an effective anti-epileptic drug and can be associated with increased risk for urolithiasis because of its effects on acid-base profile. Evidences that supported an association of topiramate and urolithiasis were limited to case reports or series. We investigated the association of topiramate and urolithiasis in a nationwide population-based cohort study. METHODS We anal...

PURPOSE Pediatric urolithiasis is believed to be uncommon, and may present without the classic symptoms of renal colic. The objectives of this study were to describe the presenting features and radiographic evaluation of pediatric urolithiasis, and to determine the accuracy of ultrasound and unenhanced computerized tomography (CT) in detecting urolithiasis. MATERIALS AND METHODS We retrospect...

OBJECTIVES Clinical features and risk factors for atazanavir (ATV)-associated urolithiasis have not been fully investigated. METHODS We reviewed all cases of ATV-containing urolithiasis identified by infrared spectrophotometry among HIV-infected patients over a 5-year period to describe their clinical features and outcome. A case-control study was performed to identify risk factors associated...

INTRODUCTION The pathophysiology of urolithiasis in infancy is not well known. The aim of this study was to investigate whether infants with urolithiasis have higher serum levels of vitamin D, as a possible risk factor for urolithiasis, compared to infants without urinary calculi. MATERIALS AND METHODS In this case-control study, 36 infants with urolithiasis (age range, 2.5 to 24 months) were...

BACKGROUND The main goal of this study is to determine the relationship between opium dependency and frequency of urolithiasis renal colics. METHODS In a cross sectional study we compared opium dependency in urolithiasis patients (case group) with non-urolithiasis patients (control group) and assessed urolithiasis related renal colics as risk factor to opium dependency prevalence.

Feline urolithiasis represents 15% of all cases of nonobstructive lower urinary tract disease in cats. Approximately 50% of feline uroliths are composed of struvite. Struvite urolithiasis commonly recurs, but optimal management may decrease its frequency. The pathophysiology and management of struvite urolithiasis are different in cats and dogs. This article focuses on struvite urolithiasis in ...

Urolithiasis is the term used to denote the formation of urinary calculi in animals including disease conditions that arise as a direct result. The terms urinary calculus and urolith on the other hand apply only to the actual calculi or uroliths formed in urolithiasis. In cattle, urinary calculi present in the bladder, on occasions enter and obstruct the urethra. This is the common form of obst...

OBJECTIVE We evaluated the relationship between dietary regimen and the incidence of urolithiasis in various regions. DESIGN This was a population-based, cross-sectional study. SETTING The setting involved 787 imaging centers in 12 socioeconomic regions in Iran. PATIENTS AND METHODS Using a multistage, stratified sampling during 4 seasonal phases, 6127 cases of urolithiasis were detected ...
