The BML lithotripter is a three-layer device consisting of a strong four-wire basket within a Teflon sheath and an overlying metal sheath. The larger lithotripsy basket or BML-3Q equivalent (BML-201) has a slightly thicker metal sheath and requires a scope with a 4.2 mm working channel.

Localizing cavitation to the kidney stone in extracorporeal shock wave lithotripsy may be desirable since cavitation appears to play a major role in both stone comminution and renal tissue damage. Use of a dual-pulse lithotripter to generate a localized and intensified cavitation field J Acoust Soc Am. 2001 Sep;110(3 Pt 1):1685-95. doi: 10.

the waveform generally does not have a shock in it—that is, there is no abrupt transition. The entire 5 µs pulse is generally referred to as a shock wave, shock pulse or pressure pulse—tech-nically, however, it is only the sharp leading tran-sition that is formally a shock.

Purpose: To analyze the efficiency and cost-utility profile of ureteroscopy versus shock wave lithotripsy for treatment of reno-ureteral stones smaller than 2 cm. Methods: Patients treated for urinary stones smaller than 2 cm were included in this study (n = 750) and divided into two groups based on technique of treatment. To assess the cost-utility profile a sample of 48 patients

The shock waves, which are generated by a machine called a lithotripter, are focused by x-ray onto the kidney stone. The shock waves travel into the body, through skin and tissue, reaching the stone where they break it into small fragments. Once your blood pressure, pulse, and breathing are stable and you are alert, you will be taken to

The lithotripter attempts to break up the stone with minimal collateral damage by using an externally-applied, focused, high-intensity acoustic pulse. The sedated or anesthetized patient lies down in the apparatus' bed, with the back supported by a water-filled coupling device. An imaging system is used to locate the stone and aim the treatment.

INTRODUCTION. The design of shock wave lithotripters has evolved significantly since the introduction of the original Dornier HM-3 in the early 1980s, which instantaneously revolutionized the surgical management for kidney and upper urinary stone diseases (Chaussy and Fuchs, 1989; Rassweiler et al., 2005).The original HM-3 (first-generation lithotripter) was designed based on

The lithotripter delivers a powerful sonic pulse that breaks the stone into smaller pieces with the least amount of collateral injury to healthy tissue. Since extracorporeal shock wave lithotripsy is non-invasive, quick to recover from, pain-free, and requires a shorter hospital stay, it is frequently utilised by doctors worldwide.

Cavitation appears to contribute to tissue injury in lithotripsy. Reports have shown that increasing pulse repetition frequency [(PRF) 0.5-100 Hz] increases tissue damage and increasing static pressure (1-3 bar) reduces cell damage without decreasing stone comminution. Our hypothesis is that overpressure or slow PRF causes unstabilized bubbles produced by one shock pulse to dissolve before
