Hyperoxaluria and oxidative stress are risk factors in calcium oxalate (CaOx) stone formation. Supplement with antioxidant could be effective in prevention of recurrent stone formation. The present study aims to evaluate the protective effects of vitamin E and vitamin C in hyperoxaluric rat. The experiment was performed in rats for 21 days. Rats were divided into 5 groups as follows: control (g...

PURPOSE Strontium has chemical similarity to calcium, which enables the replacement of calcium by strontium in biomineralization processes. Incorporating strontium into human bone and teeth has been studied extensively but little research has been performed of the incorporation of strontium into urinary calculi. We used synchrotron based x-ray fluorescence and x-ray absorption techniques to exa...

Abstract Aim The LithoClast Trilogy Lithotripter is the latest generation lithotripter. It has four modifiable settings for stone fragmentation - Impact (0-100%), frequency (0-12Hz), ultrasound (0-100%) and suction (0-100%). configuration different types unknown. We aim to determine optimal types. Method Calcium oxalate, calcium phosphate, uric acid struvite 2cm3 phantoms were created using Beg...

Kidney stone consists of various organic, inorganic and semi organic compounds. Mineral oxalate monohydrate and di-hydrate is the main inorganic constituent of kidney stones. However, mechanisms leading to the formation of mineral oxalate kidney stones are not clearly understood. In this field of study, there are several hypotheses including nucleation, crystal growth and or aggregation of form...

Based on the 89 stones treated by ESWL therapy alone, the factors which influence the number of ESWL shots were analyzed. Stone volume was calculated by summing up the value "length x short axis" for each stone. The value correlated well with the number of shots needed to disintegrate the stone (p less than 0.01). The stones below the pelvis-ureteral junction needed twice shots compared with st...

Colonization with Oxalobacter formigenes may reduce the risk of calcium oxalate kidney stone disease. To improve our limited understanding of host-O. formigenes and microbe-O. formigenes interactions, germfree mice and mice with altered Schaedler flora (ASF) were colonized with O. formigenes. Germfree mice were stably colonized with O. formigenes, which suggests that O. formigenes does not requ...

OBJECTIVES To evaluate the ability of non contrast computed tomography (NCCT) to predict stone composition and fragility for treatment with extracorporeal shock wave lithotripsy (ESWL). METHODS 27 stones of about 10 mm from patients who had undergone different endourological procedures were collected. All patients had been evaluated with NCCT. To perform in vitro ESWL an experimental device w...

OBJECTIVE To assess the evidence-based literature supporting the use of traditional Chinese medicine Kampo herbal and Acupuncture in stone disease management. MATERIALS AND METHODS Four of the most commonly used herbal components of Kampo medicine in the treatment of stone disease are described according to their in vitro and in vivo effects. We also reviewed the role of Acupuncture in urolog...
