the effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
[Stone burden on extracorporeal shock wave lithotripsy].
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...
متن کاملEffects of hydrochlorothiazide on kidney stone therapy with extracorporeal shock wave lithotripsy
OBJECTIVE The aim of this investigation was to assess the efficacy of hydrochlorothiazide as a hypocalciuric diuretic on stone-free rate of renal pelvic calculi after extracorporeal shock wave lithotripsy (ESWL). MATERIALS AND METHODS A double-blind, placebo-controlled randomized clinical trial was conducted and 52 patients with renal pelvic calculi (diameter ≤2 cm) were enrolled from Februar...
متن کاملThe Wow Factor of e-Health
Some of the latest healthcare buzzwords are e-health, m-health or telemedicine. Is this the latest fad or is there indeed a lasting wow factor? The use of Information and Communications Technologies (ICT) to support the achievement of health outcomes, namely, e-health has the potential to transform the manner in which health services are delivered. A plethora of applications are emerging though...
متن کاملHow do stone attenuation and skin-to-stone distance in computed tomography influence the performance of shock wave lithotripsy in ureteral stone disease?
BACKGROUND Shock wave lithotripsy (SWL) is a noninvasive, safe, and efficient treatment option for ureteral stones. Depending on stone location and size, the overall stone-free rate (SFR) varies significantly. Failure of stone disintegration results in unnecessary exposure to shock waves and radiation and requires alternative treatment procedures, which increases medical costs. It is therefore ...
