..Our data provide evidence that overweight is associated with a high proportion of uric acid stones in patients less than 60 years of age, whereas beyond this limit, advancing age is the main risk factor...

..To determine the value of mid-infrared spectroscopy (MIRS) of ureteral stent encrustations in predicting urinary stone composition...

..This review summarizes the genetic and metabolic mechanisms underlying stone formation and renal disease, along with the diagnosis and management of APRT deficiency...

..Low-dose acquisition did not lower the performances (P < 0.05). This entirely automated approach eliminates manual intervention on the images by the radiologist while providing identical performances including for low-dose protocols...

..However, little is known as to the significance of the CR of CA in the absence of struvite in idiopathic calcium phosphate stones...

..To determine whether a subgroup of patients with severe but nonprogressive renal dysfunction exist and to characterize this subgroup...

..Urinary crystal precipitation is the necessary initial step in kidney stone formation. However, clinical relevance of crystalluria in the evaluation of stone formers is disputed...

..In conclusion, both accurate morphologic and FTIR analysis of stones and serial crystalluria determination should be more largely used, in view of their value in the diagnosis and management of renal stone formers...

..It is found that Ca(2+) compounds differ between calcified and non-calcified cartilage areas. In calcified areas they appear to be mainly involved in calcifications, namely Ca(2+) crystals...

..CONCLUSION: The composition of mineral encrustation of double J stents is a good marker of stone formation. This constitutes an alternative method that can be used by urologists when no stone is available for spectrophotometric analysis...

..To verify whether this difference in the epidemiological profile is still observed today, we analysed renal stones collected in various regions of the globe and compared their composition to that of stones observed in France...

..The objective of this article is to review the metabolic syndrome in order to help urologists to recognize this syndrome so that they can identify patients requiring more specific management and medical follow-up...

..We examined whether stone composition in pregnant women reflects peculiar pathophysiological conditions...

..002). The absence of a TA is a predictive factor for the presence of COM stones (p = 0.008). Hence, the association of NCHCT and Doppler enables the accurate classification of the five types of stones in vitro...

..We anticipate that this experimental model will be useful to test treatment strategies aimed at decreasing the accelerated atherosclerosis and arterial calcification in uremia...

..Early diagnosis is crucial for initiation of effective treatment with allopurinol and for prevention of renal complications...

..Many reports have described atazanavir-associated urolithiasis, but this is the first case that describes chronic granulomatous nephropathy...

..Analysis of every first stone both in children and in adults should never be neglected, in order to early detect unusual forms of nephrolithiasis requiring laboratory evaluation and deep etiologic treatment...

..Our aim was to determine, using CT attenuation values, the chemical composition of 241 human renal stones placed in a jelly phantom and to analyze the influence of respiratory motion on the classification...

..Accordingly, it is suggested that patients with UA stones, especially if overweight, should be screened for the presence of type 2 diabetes or components of the metabolic syndrome...
