| extracorporeal shock wave lithotripsy | <procedure> This procedure uses sound waves delivered inside a water bath to pulverise kidney stones painlessly inside the body. (11 Nov 1997) |
|---|---|
| shock wave lithotripsy | A method of fragmenting calculi. (05 Mar 2000) |
| electrohydraulic shock wave lithotripsy | Destruction of calculi (urinary tract or other) by fragmentation using shock waves sent transcutaneously. (05 Mar 2000) |
| extracorporeal | <anatomy> Situated or occurring outside the body. Origin: L. Corpus = body (18 Nov 1997) |
| extracorporeal circulation | Diversion of blood flow through a circuit located outside the body but continuous with the bodily circulation. (12 Dec 1998) |
| extracorporeal dialysis | Haemodialysis performed through an apparatus outside the body. (05 Mar 2000) |
| extracorporeal membrane oxygenation | Application of a life support system that circulates the blood through an oxygenating system, which may consist of a pump, a membrane oxygenator, and a heat exchanger. Examples of its use are to assist victims of smoke inhalation injury, respiratory failure, and cardiac failure. (12 Dec 1998) |
| lithotripsy | Known as extracorporeal shock wave lithotripsy, this procedure uses sound waves delivered inside a water bath to pulverize kidney stones painlessly inside the body. (27 Sep 1997) |
| lithotripsy, laser | Fragmentation of calculi, notably urinary or biliary, by laser. It is usually performed with an endoscopically guided pulsed tunable dye laser, a combination of a pulsed laser and a dye laser usually referred to as a pulsed dye laser. It is both safe and effective when extracorporeal shockwave lithotripsy is infeasible or unsuccessful. (12 Dec 1998) |
| ultrasonic | Relating to energy waves similar to those of sound but of higher frequencies (above 30,000 Hz). Origin: ultra-+ L. Sonus, sound (05 Mar 2000) |
| ultrasonic cardiography | Echocardiography is a diagnostic test which uses ultrasound waves to make images of the heart chambers, valves and surrounding structures. It can measure cardiac output and is a sensitive test for inflammation around the heart (pericarditis). It can also be used to detect abnormal anatomy or infections of the heart valves. (12 Dec 1998) |
| ultrasonic cephalometry | Measurement of the foetal head by ultrasound. (05 Mar 2000) |
| ultrasonic egg recovery | Obtaining an egg for in vitro fertilization by means of an ultrasonically guided needle aspiration of ovarian follicles; may be performed transvesically or via the cul-de-sac. (05 Mar 2000) |
| ultrasonic lithotresis | The demolition of calculi by high frequency sound waves. (05 Mar 2000) |
| ultrasonic microscope | <instrument> A microscope that has lenses designed to use acoustic energy so that the ultrasonic wavelengths may be utilised; by means of transducers, the information is translated to a form that may be visualised or recorded. (05 Mar 2000) |
