Predicting the sawability of the dimension stone is one of the most important factors involved in production planning. Moreover, this factor can be used as an important criterion in the cost estimation and planning of the stone plants. The main purpose for carrying out this work was to rank the sawability of the dimension stone using the PROMETHEE method. In this research work, four important p...

PURPOSE To identify the parameters on noncontrast computed tomography (NCCT) that best predict the success of shock wave lithotripsy (SWL). MATERIALS AND METHODS We reviewed the records of 75 patients who underwent SWL for urinary calculi measuring 5 to 20 mm. Using NCCT images, we estimated the largest stone cross-sectional area and contoured the inner edge of the stone. Clinical outcome was...

PURPOSE To identify the role of shock wave lithotripsy (SWL) and flexible ureterorenoscopy (f-URS) on the stone recurrence, in the management of 10-20 millimeter lower pole stone (LPS) with medium follow-up outcomes. MATERIALS AND METHODS The patients' charts which were treated with SWL or f-URS for LPS between January 2011 and September 2013 were analyzed, retrospectively. Patients who had a...

PURPOSE We retrospectively investigated the factors that affect the success of rigid ureteroscopy in the pediatric population for the management of pediatric ureteral stones. PATIENTS AND METHODS We present a retrospective review of 61 consecutive pediatric patients who underwent 66 rigid ureteroscopy procedures for ureteral stone management. The effects of sex, age, stone diameter, stone loc...

statement of the problem although the primary use of tissue conditioners is to treat abused mucosa, these materials are also frequently used as functional impression materials. insufficient information is available on the effect of these materials on the surface of dental stone casts. purpose this study evaluated the effect of a tissue conditioner (acrosoft) on surface roughness of dental stone...

At present, the clinical significance of existing physicochemical and biological evidence and especially the results we have obtained from our previous in vitro experiments have been analyzed, and we have come to the conclusion that hippuric acid (C6H5CONHCH2COOH) is a very active solvent of Calcium Oxalate (CaOX) in physiological solutions. Two types of experiments have been discussed: clinica...

molecular diffusion is one of the important contaminant transport mechanisms through soil and rocks. in this study the molecular diffusion coefficient of marl stone and sand stone from the urmia city landfill site was determined using the best fit method of the observed laboratory data and the predicted theoretical data. the marl stone and sand stone samples were tested under the conditions of ...

OBJECTIVES To assess the probability of spontaneous stone passage and its predictors after drainage of obstructed kidney by JJ stent, as insertion of an internal ureteric stent is often used for renal drainage in cases of calcular ureteric obstruction. PATIENTS AND METHODS Between January 2011 and June 2013, patients for whom emergent drainage by ureteric stents were identified. The patients'...
