Numerical simulations are used to evaluate the damage potential of the shock-induced collapse of a pre-existing gas bubble near a rigid surface. In the context of shock wave lithotripsy, a medical procedure where focused shock waves are used to pulverize kidney stones, shock-induced bubble collapse represents a potential mechanism by which the shock energy directed at the stone may be amplified...

OBJECTIVE To evaluate the role of mannitol infusion in preventing or ameliorating renal injury that accompanies shock wave lithotripsy as measured by changes in resistive index (RI). METHODS Between February and September 2006, 38 patients (28 men and 10 women) underwent extracorporeal shock wave lithotripsy (ESWL) for radiologically documented renal stones in The Surgical Specialties Hospita...

The design and construction of autonomous electronic instrumentation to generate fast high voltage discharges (6 to 10 kV) on a piezoelectric crystal array, in order to produce underwater shock waves, is described. If properly focused, hundreds of these shock waves are capable of destroying renal and ureteral calculi. This clinical treatment, developed more than 20 years ago, is known as extrac...

BACKGROUND the present study was designed to compare the efficacy, tolerability and safety of dexmedetomidine and fentanyl when combined with propofol during extracorporeal shock wave lithotripsy in children. METHODS fifty children aged 3-8 years, the American Society of Anesthesiologists status I and II, scheduled for elective extracorporeal shock wave lithotripsy were randomly allocated to ...

BACKGROUND Extracorporeal Shock Wave Lithotripsy (ESWL) is a simple and non-invasive technique in which renal and ureteric calculi are pulverised into small fragments by shockwaves and then allowed to pass spontaneously in small fragments along with urine. Effective ESWL requires a co-operative patient who will remain immobilize on the lithotripsy table comfortably for which different anaesthet...
