BACKGROUND Optimum management to prevent recurrent kidney stones is uncertain. PURPOSE To evaluate the benefits and harms of interventions to prevent recurrent kidney stones. DATA SOURCES MEDLINE, Cochrane, and other databases through September 2012 and reference lists of systematic reviews and randomized, controlled trials (RCTs). STUDY SELECTION 28 English-language RCTs that studied tre...

OBJECTIVE During augmentation and Mitrofanoff procedures, conduits are usually implanted into the posterior bladder wall. Anatomical considerations may necessitate an anterior conduit. To compare the relative drainage efficiency in patients with posterior and anterior conduits, we studied their rates of bladder stone formation and urinary tract infection (UTI). MATERIALS AND METHODS A retrosp...

In this study, screw and nail withdrawal resistance of fir (Abies nordmanniana), oak (Quercus robur L.) black pine (Pinus nigra Arnold) and Stone pine (Pinus pinea L.) wood were determined and compared. The data represent the testing of withdrawal resistance of three types of screws as smart, serrated and conventional and common nails. The specimens were prepared according to TS 6094 standards....

PURPOSE We determined by statistical analysis whether method of management is associated with risk of bladder stone formation in spinal cord injured patients. MATERIALS AND METHODS A retrospective cohort study was performed of 457 patients admitted to Stoke Mandeville Hospital Spinal Injuries Center between 1985 and 1990 with more than 6 months of followup. Analysis included Cox regression an...

A62-years old female patient presented to another hospital with complaints of nausea, vomiting and upper right quadrant pain since one week, and abdominal ultrasonography revealed that intrahepatic bile ducts and the common bile duct were dilated. Magnetic resonance cholangiopancreatography was performed at the same hospital and a filling defect of 8.5 mm was noted at the mid level of common bi...

sakiabad is one of the most important sites in the choqakhor pond’s basin which show remains of nomadic settlement in the chalcolithic period. salvage excavation was carried out for two months during autumn and winter of 2011. by digging of five trenches10×10 m, one of the nomadic settlements was exposed with mud and stone architecture made from the local materials in the region. exposed space ...

We study the relative error in conductance calculations, for simulated flow of a single component single phase fluid through a capillary in three dimensions, by the Lattice Boltzmann (LB) method with bounce-back boundary conditions. The relative error with respect to analytical results for capillary cross-sections of circular, triangular and square shapes are calculated as a function of the cro...

in this paper, our purpose is twofold. firstly, the tensor andresiduum operations on $l-$nested systems are introduced under thecondition of complete residuated lattice. then we show that$l-$nested systems form a complete residuated lattice, which isprecisely the classical isomorphic object of complete residuatedpower set lattice. thus the new representation theorem of$l-$subsets on complete re...

The classical island and one-dimensional stepping-stone models of population genetic structure developed for animal populations are extended to hermaphrodite plant populations to study the behavior of biparentally inherited nuclear genes and organelle genes with paternal and maternal inheritance. By substituting appropriate values for effective population sizes and migration rates of the genes ...

OBJECTIVES To determine whether stone-formers have higher BP than controls drawn from the general population and matched for age, sex and ethnic origin and to compare the relationship between sodium and calcium excretion in the two groups. PATIENTS AND METHODS Thirty-six patients [mean (+/-standard deviation, SD) = 49.0 +/- 11.7 years; range 27-70 years] with kidney or ureteric stones and 108...
