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...
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'...
Bergsland, Kristin J., Jennifer K. Kelly, Brian J. Coe, and Fredric L. Coe. Urine protein markers distinguish stone-forming from non-stone-forming relatives of calcium stone formers. Am J Physiol Renal Physiol 291: F530–F536, 2006. First published April 18, 2006; doi:10.1152/ajprenal.00370.2005.—We have investigated urine protein inhibitors of calcium oxalate crystallization to determine whethe...
bladder stone is an old known mankind disease. it is a problem of male and is more common in children of underdeveloped countries and old age men in industrialized countries. giant bladder stone in a female without any underlying problem is even a rarer entity. the case alone is hence being reported in view of its rarity and persistence of stone from childhood
Introduction: Aim was to study the influence of serum testosterone and urinary citrate on the formation of urinary stones in men and women, and to apply the findings for preventing urolithiasis. Methods: We studied 200 patients (100 were men and 100 women) who had referred to the urology clinic at Imam Khomeini hospital and Seda Sima ESWL center. In both groups, 50 were stone formers and 50 we...
