A set of Shock Wave Lithotripsy(SWL) related experimental observations including 3D dynamic crack propagation, reported in literature, are simulated with the aim of understanding the fragmentation of kidney stone with SWL. Extracorporeal shock wave lithotripsy (ESWL) is the fragmentation of kidney stones by focusing an ultrasonic pressure pulse onto the stones. 3D models with fine discretizatio...

OBJECTIVES To present our series of patients with ureteral stent encrustation and give indwelling times and management. Encrustation is one of the most serious complications of ureteral stents. METHODS A retrospective review was undertaken of all encrusted stents during a 4-year period. The inclusion criterion was a stent that required some form of intervention above the ureteral orifice to r...

The traditional management of obstructive salivary disorders has been replaced by minimally-invasive gland-preserving techniques including shock-wave lithotripsy, sialendoscopy, interventional radiology and endoscopically video-assisted trans-oral and cervical stone retrieval, of which sialendoscopy is considered to be the method of first choice. Primary endoscopically controlled stone extracti...

During a period of 24 months 693 consecutive patients with symptomatic gall bladder stones (526 males, 167 females; mean age 51 years, range 18-89) were treated by extracorporeal shock wave lithotripsy with a Piezolith 2300. The procedure was carried out on an out-patient basis without analgesics or sedatives. Concomitant chemolitholytic treatment (ursodeoxycholic and chenodeoxycholic acid 7.5 ...

BACKGROUND This study compared the clinical outcomes of extracorporeal shock wave lithotripsy between elderly (aged $65 years) and non-elderly (aged <65 years) patients. METHODS A retrospective review of medical records was performed on 483 (non-elderly: 245, elderly: 238) patients with upper urinary tract stones who underwent shock wave lithotripsy between 2007 and 2015. The demographic data...

PURPOSE Subcapsular or perinephric hematoma is one of the most frequent and potentially serious complications of extracorporeal shock wave lithotripsy (SWL). We determined the incidence of and risk factors for renal hematomas following electromagnetic shock wave lithotripsy. MATERIALS AND METHODS Between February 1999 and August 2003, 570 SWL treatments were performed using a Modulith SLX ele...

Urinary stones are the third most common affliction of the urinary tract. They are exc-eeded only by urinary tract infections and pathological conditions of the prostate1. Urolithiasis affects 5-15% of the population worldwide. Recurrence rates are close to 50% and the cost of treatment for urolithiasis to individuals and society is high.2 Data indicates that up to 98% of urinary tract stones w...

J. Al-Nabulsi, H. Amasha, B. Altrabsheh, B. Al-Naami Biomedical Engineering Department, Faculty of Engineering, Hashemite University, Zarqa, Jordan Extracorporeal shock wave lithotripsy (ESWL) employs high-energy shock waves that propagate through the body and focus on th reak it into small grains, which travel out of the body along with the urine. The distance between lithotripsy longdes tends...
