PURPOSE: To investigate the effect of performing shockwave lithotripsy (SWL) before retrograde intrarenal surgery (RIRS) on the treatment outcomes of patients with nephrolithiasis. MATERIALS AND METHODS: The data of 189 patients with renal stones who underwent RIRS from July 2007 to July 2014 was reviewed retrospectively. Patients with stones larger than 1.5 cm were recommended to undergo SWL before RIRS. Patients were divided into 2 groups based on whether the preoperative SWL was performed (group 1, n=68) or not (group 2, n=121)...

REVIEW
Jordan J Hinman, Kenneth S Suslick
Recent applications of ultrasound to the production of nanostructured materials are reviewed. Sonochemistry permits the production of novel materials or provides a route to known materials without the need for high bulk temperatures, pressures, or long reaction times. Both chemical and physical phenomena associated with high-intensity ultrasound are responsible for the production or modification of nanomaterials. Most notable are the consequences of acoustic cavitation: the formation, growth, and implosive collapse of bubbles, and can be categorized as primary sonochemistry (gas-phase chemistry occurring inside collapsing bubbles), secondary sonochemistry (solution-phase chemistry occurring outside the bubbles), and physical modifications (caused by high-speed jets, shockwaves, or inter-particle collisions in slurries)...

About 10% of the people is the subject of an episode of kidney stones during their lifetime, about 70% of these people undergoes relapses. About 80% of the urinary stones contains calcium, of wich 80% is formed of calcium oxalate, in pure form or associated with calcium phosphate. Therefore we can saythat in most cases (about 65%) the urinary stones are composedof calcium oxalate. Use of supplements of potassium citrate and magnesium citrate can help in the prevention of kidney stones of calcium oxalate, but mostly they can be used in the days before a shockwaves lithotripsy treatment to make the stones more fragile to the effect of the shock waves...

The regeneration of water wells is an urgent problem nowadays, when drilling of new wells becomes more and more expensive. Formation damage leads to a reduction of the formation's permeability and/or pore volume which in turn inhibits the ability of the water to flow from the reservoir formation into the wellbore. A new technology that uses high-power ultrasound to remove formation damage of water wells has been developed. The effectiveness of regeneration of wells can be enhanced if ultrasound and shockwaves are used during the same treatment...

Graphene is one of the highly explored nanomaterials due to its unique and extraordinary properties. In this study, by utilizing a hydrothermal reduction method, graphene oxide (GO) was successfully converted to reduced graphene oxide (RGO) without using any toxic reducing agents. Following this, with the use of ultrasonic cavitation, profoundly stable few layer thick RGO nanodispersion was generated without employing any stabilizers or surfactants. During ultrasonication, shockwaves from the collapse of bubbles cause a higher dispersing energy to the graphene nanosheets which surpass the forces of Van der Waal's and π-π stacking and thus pave the way to form a stable aqueous nanodispersion of graphene...

CONTEXT: Extracorporeal shockwave lithotripsy (SWL) is the first-line treatment for renal calculi in most cases. Recent technology has allowed lithotriptor machines to localize stones using fluoroscopy or ultrasound (US). AIM: The aim of this study is to compare stone free rates (SFR) using two techniques. METHODS: This is a single center retrospective cohort study. We have studied 95 patients with renal calculi undergoing first SWL treatment with localization using US (48 pts) and fluoroscopy (47 pts)...

OBJECTIVES: Although previous studies have indicated that stone heterogeneity can affect shock wave lithotripsy outcomes, there is no established measurement of stone heterogeneity on computed tomography imagery. We investigated whether variation coefficient of stone density can predict shock wave success. MATERIALS AND METHODS: We conducted a retrospective review of 245 patients with urinary calculi who had undergone shock wave lithotripsy. We compared the predictive powers of treatment success between variation coefficient of stone density and other parameters associated with computed tomography attenuation...

BACKGROUND: In recent years, the incidence of urinary stone disease reportedly has been increasing. The use of shockwave lithotripsy has seen low success rates, the inefficacy of a single session, and the need for general anaesthesia in children; additionally, children are exposed to radiation. These suboptimal treatment conditions have all led to ureteroscopy (URS) becoming the treatment method of choice for paediatric ureter stones. The aim of this study is to examine the effectiveness of 4...

Shock wave treatment (SWT) was shown to induce regeneration of ischaemic myocardium via Toll-like receptor 3 (TLR3). The antimicrobial peptide LL37 gets released by mechanical stress and is known to form complexes with nucleic acids thus activating Toll-like receptors. We suggested that SWT in the acute setting prevents from the development of heart failure via RNA/protein release. Myocardial infarction in mice was induced followed by subsequent SWT. Heart function was assessed 4 weeks later via transthoracic echocardiography and pressure-volume measurements...

Mechanochemistry deals with the interface between the chemical and the mechanical worlds and explores the physical and chemical changes in materials caused by an input of mechanical energy. As such, the chemical and physical effects of ultrasound, i.e., sonochemistry, are forms of mechanochemistry. In this paper, fragmentation of ionic crystals during ultrasonic irradiation of slurries has been quantitatively investigated: the rate of fragmentation depends strongly on the strength of the materials (as measured by Vickers hardness or by Young's modulus)...

OBJECTIVE: The objective of this meta-analysis was to investigate the efficacy of extracorporeal shock wave therapy in the treatment of recalcitrant plantar fasciitis without local anesthesia. METHODS: The Cochrane Library, EMBASE, PubMed, and Web of Science databases were searched from inception to September 2015 for randomized controlled trials comparing ESWT without local anesthesia versus placebo for treatment of plantar fasciitis in adults. The primary outcome was the 12-week post-intervention success rate of reducing the visual analog scale score by 60% from baseline at the first step in the morning, reducing the VAS score by 60% from baseline during daily activities, reducing the Roles and Maudsley score, reducing overall heel pain, and reducing pain after applying a force meter...

BACKGROUND: Extracorporeal shock wave lithotripsy (ESWL) is an important tool for the management of urolithiasis. The effects of shockwaves on tissues are established. The aim of this meta-analysis is to evaluate the microscopic semen characteristics of young men before and after ESWL treatment for lower ureteral calculi. METHODS: Literature searches were performed following the Cochrane guidelines. We conducted a systematic review and meta-analysis that included six trials that investigated the effects of ESWL on semen parameters, including sperm concentration, motility, and hematospermia...

A novel multiphase fluid-solid coupled computational framework is applied to investigate the interaction of a kidney stone immersed in liquid with a lithotripsy shock wave (LSW) and a gas bubble near the stone. The main objective is to elucidate the effects of a bubble in the shock path to the elastic and fracture behaviors of the stone. The computational framework couples a finite volume two-phase computational fluid dynamics (CFD) solver with a finite element (FE) computational solid dynamics (CSD) solver...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is recommended for treating staghorn stones or stones measuring > 20 mm. Extracorporeal shockwave lithotripsy (ESWL) or flexible ureteroscopy (URS) may be used as a complement. However, PCNL can cause trauma to the kidney parenchyma, and patients may find a noninvasive procedure, such as ESWL, to be more attractive. OBJECTIVES: The aim of this study was to evaluate the clinical efficiency of MiniJFil® stenting associated with ESWL or second-line URS for the treatment of medium-to-large kidney stones...
