PURPOSE: Despite the increasing use of advanced 3D imaging techniques and 3D printing, these techniques have not yet been comprehensively compared in a surgical setting. The purpose of this study is to explore the effectiveness of five different advanced imaging modalities during a complex renal surgical procedure. METHODS: A patient with a horseshoe kidney and multiple large, symptomatic stones that had failed Extracorporeal Shock Wave Lithotripsy (ESWL) and ureteroscopy treatment was used for this evaluation...

OBJECTIVE: To investigate the effectiveness of modified mechanical percussion for eliminating upper urinary tract (UUT) stone fragments after extracorporeal shock wave lithotripsy (SWL). MATERIALS AND METHODS: We assigned patients aged 18-60 years with UUT calculi to the modified mechanical percussion (trial) or observation (control) group. Kidney-ureter-bladder radiography and ultrasound were used for diagnostic evaluation. The primary outcome was the stone-expulsion rate (SER) at 6 hours...

BACKGROUND: Hemodialysis (HD) patients have a high risk of sudden death but limited vascular access and high complication rates from transvenous implantable cardioverter-defibrillators (ICDs). Subcutaneous ICDs (S-ICD) may be an alternative, but dynamic ECG changes may result in inappropriate shocks. This study aims to define the screen failure rate for S-ICD in patients pre- and post-HD. METHODS: ECG waveforms were obtained using electrodes mimicking the S-ICD sensing vectors in an unselected test group of chronic HD patients and a control group of ICD-eligible non-dialysis patients...

BACKGROUND: The action mechanism of stimulation toward spiral waves (SWs) owing to the complex excitation patterns that occur just after point stimulation has not yet been experimentally clarified. OBJECTIVE: This study sought to test our hypothesis that the effect of capturing excitable gap of SW by stimulation can also be explained as the interaction of original phase singularity (PS) and PSs induced by the stimulation on the wave tail (WT) of the original SW...

Interventional treatment of stones essentially consists of three treatment modalities. Extracorporeal shockwave lithotripsy (ESWL), in addition to uterorenoscopy (URS) and percutaneous nephrolitholapaxy (PCNL) is an essential treatment pillar and is the only noninvasive therapy option for the treatment of urinary stones. After a long period of ESWL being the leading choice in stone treatment, the number of SWL interventions diminished in recent years in favor of the other two treatment modalities (URS and PCNL)...

Purpose: This study aims to assess the predictive factors and treatment outcomes of Steinstrasse formation following shock wave lithotripsy (SWL) for ureter stone. Materials and Methods: The medical records of 1,418 ureter stone patients who underwent one-session SWL from November 2005 to May 2013 at our medical institute were retrospectively reviewed. Finally, 551 patients met inclusion criteria. Maximal length and location of stone, stone attenuation (Hounsfield units), and skin-to-stone distance (SSD) were determined on pretreatment non-contrast computed tomography...

Objective: To determine the success rate of percutaneous nephrolithotomy (PNL) in kidney stones over 50 milimeters. Material and methods: Twenty-four patients with a renal stone size of >50 mm between January 2007 and December 2016 were enrolled. Stone-free and complication rates were investigated. Results: Twenty-one (87.5%) patients were male and 3 (12.5%) were female. Fifteen (62.5%) stones were located in the right, and 9 (37.5%) in the left kidney...

The first choice of treatment for patients with plantar fasciitis is non-invasive treatment, rather than corticosteroid injection (CSI). However, no comprehensive study has compared the effectiveness of CSI with non-invasive treatments for plantar fasciitis. We conducted a meta-analysis comparing CSI and non-invasive treatment effects on plantar fasciitis. The primary outcome was pain reduction. Nine randomized controlled trials comparing CSI with 4 non-invasive treatment types were included. A trend favoring CSI over non-invasive treatments was indicated regarding reduction in the visual analogue scale (VAS) score at 1-1...

OBJECTIVES: Extracorporeal shockwave therapy (ESWT) and corticosteroid injection (CSI) are treatment options for plantar fasciitis. Their clinical outcome comparison remains a debate. Also, the thickness changes of the plantar fascia on objective evaluation under the medium energy ESWT and CSI therapy are elusive. METHODS: A total of 97 patients with chronic plantar fasciitis were enrolled in the randomized prospective trial. Forty-seven patients received extracorporeal shock wave therapy (ESWT), and fifty patients received corticosteroid injection (CSI)...

The aim of this study is to investigate the effects of extracorporeal shock wave therapy (ESWT) on muscle rheological and functional properties in a population of young athletes. Thirty-two football and basketball players were recruited and randomized into two groups. The athletes underwent three sessions of therapy administered every five days to the thigh muscles. The treatment consisted of ESWT (electromagnetic generator, Energy Flux Density=0.03 mJ/mm2) or a placebo treatment bilaterally on the quadricep and femoral bicep muscles...

MATERIALS AND METHODS: This is a retrospective study including 79 children, who had renal stone and underwent either shock wave lithotripsy or flexible ureteroscopy between January 2007 and June 2017. Of those, 38 patients underwent shock wave lithotripsy assigned as group 1 and 41 patients underwent flexible ureteroscopy assigned as group 2...

OBJECTIVE: To compare the medium- and long-term effect of pneumatic ballistic extracorporeal shock wave versus ultrasound-guided hormone injection in the treatment of plantar fasciitis. METHODS: The clinical data were collected from patients with plantar fasciitis admitted to PLA General Hospital pain department from September, 2015 to February, 2017. The patients were randomly divided into ultrasound-guided drug injection group and shock wave group. The therapeutic parameters including the numerical rating scale (NRS) scores in the first step pain in the morning, American Orthopedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Scale, and thickness of the plantar fascia were monitored before and at 1 week, 1 month, 3 months, and 6 months after the treatment...

Rapid membrane damage of optically trapped red blood cells was observed at trapping powers ≥ 280 mW. An excellent agreement between the estimated laser induced thermal gradient across trapped cell's membrane and that typically required for membrane electropermeabilization suggests a mechanism involving temperature gradient induced electropermeabilization of membrane. Also the rapid collapse of the trapped cell due to membrane rupture was seen to cause shock waves in the surroundings permeabilizing nearby untrapped cells...

Isolated spontaneous renal artery dissection (RAD) without known trauma is rare, and its etiology has not been determined. However, notable risk factors including hypertension, strenuous exercise, connective tissue disorders, atherosclerosis, extracorporeal shock wave lithotripsy, and cocaine abuse have been reported. To the best of our knowledge, isolated RAD caused by lumbar vertebra osteophytes in patients with degenerative lumbar scoliosis has not been reported in the literature. In this article, we present a case of RAD caused by lumbar vertebra osteophyte in a patient with degenerative scoliosis and discuss the management of the disease...

Model equations with cubic nonlinearity are developed for a plane shear wave of finite amplitude in a relaxing medium. The evolution equation for progressive waves is solved analytically for a jump in stress that propagates into an undisturbed medium. Weak-shock theory is used to determine the amplitude and location of the shock when the solution predicts a multivalued waveform. The solution is similar to that obtained by Polyakova, Soluyan, and Khokhlov [Sov. Phys. Acoust. 8, 78-82 (1962)] for a compressional wave with quadratic nonlinearity in a relaxing fluid...
