Noncontrast Computed Tomography Parameters for Predicting Shock Wave Lithotripsy Outcome in Upper Urinary Tract Stone Cases.

Biomed Res Int 2018 2;2018:9253952. Epub 2018 Dec 2.

Department of Urology, Wakayama Medical University, 811-1 Kimiidera, Wakayama 641-0012, Japan.

Kidney stones are a major public health concern with continuously increasing worldwide prevalence. Shock wave lithotripsy (SWL) is the first line treatment choice for upper urinary tract calculi with ureteroscopy and has advantages of safety and noninvasiveness, but the treatment success rate of SWL is lower than that of other therapies. It is therefore important to identify predictive factors for SWL outcome and select a suitable treatment choice for patients with upper urinary tract calculi. Read More

Recent advances in infrared laser lithotripsy [Invited].

Biomed Opt Express 2018 Sep 30;9(9):4552-4568. Epub 2018 Aug 30.

Department of Physics and Optical Science, University of North Carolina at Charlotte, NC 28223, USA.

The flashlamp-pumped, solid-state, pulsed, mid-infrared, holmium:YAG laser (λ = 2120 nm) has been the clinical gold standard laser for lithotripsy for over the past two decades. However, while the holmium laser is the dominant laser technology in ureteroscopy because it efficiently ablates all urinary stone types, this mature laser technology has several fundamental limitations. Alternative, mid-IR laser technologies, including a thulium fiber laser (λ = 1908 and 1940 nm), a thulium:YAG laser (λ = 2010 nm), and an erbium:YAG laser (λ = 2940 nm) have also been explored for lithotripsy.

The impact of dust and confinement on fragmentation of kidney stones by shock wave lithotripsy in tissue phantoms.

J Endourol 2018 Dec 29. Epub 2018 Dec 29.

University of Washington School of Medicine, 12353, Department of Urology, Seattle, Washington, United States.

Objective The goal was to test whether stone composition and kidney phantom configuration affected comminution in shock wave lithotripsy (SWL) laboratory tests. Confinement may enhance the accumulation of dust and associated cavitation bubbles in the fluid surrounding the stone. It is known that high shock wave delivery rates in SWL are less effective because bubbles generated by one shock wave do not have sufficient time to dissolve, thereby shielding the next shock wave.

Urologiia 2018 Dec(5):175-181

European Medical Center, Moscow, Russia.

Retrograde intrarenal surgery (RIRS) is a rapidly developing field of endoscopic management of urolithiasis. Previously considered an additional technique in patients with lower calyx stones that do not respond to extracorporeal shock wave lithotripsy, now the RIRS along with percutaneous surgery is gaining a leading position in the management of kidney stones. Currently, it is recommended as the main surgical modality for treating stones less than 2 cm, especially in cases where extracorporeal shock wave lithotripsy is not feasible or not desirable.

Energy shielding by cavitation bubble clouds in burst wave lithotripsy.

J Acoust Soc Am 2018 Nov;144(5):2952

Center for Industrial and Medical Ultrasound, Applied Physics Laboratory, University of Washington, 1013 Northeast 40th Street, Seattle, Washington 98105, USA.

Combined laboratory experiment and numerical simulation are conducted on bubble clouds nucleated on the surface of a model kidney stone to quantify the energy shielding of the stone caused by cavitation during burst wave lithotripsy (BWL). In the experiment, the bubble clouds are visualized and bubble-scattered acoustics are measured. In the simulation, a compressible, multi-component flow solver is used to capture complex interactions among cavitation bubbles, the stone, and the burst wave. Read More
