Combined laparoscopic pyelolithotomy and endoscopic pyelolithotripsy for staghorn calculi. Long-term follow-up results from a case series [PDF]

open access: yes, 2015
Purpose: Staghorn renal stones are a challenging field in urology. Due to their high recurrence rates, particularly those associated with an infective process, a complete removal is the ultimate goal in their management.

Efficacy and safety of novel digital single-operator peroral cholangioscopy-guided laser lithotripsy for complicated biliary stones

open access: yesEndoscopy International Open, 2017
Background/study aims Laser lithotripsy can effectively fragment complicated biliary stones, but current cholangioscopes are limited by fragility, restricted mobility or moderate visual resolution.

Pneumatic Lithotripsy Versus Laser Lithotripsy for Ureteral Stones

open access: yesJournal of Lasers in Medical Sciences, 2018
Introduction: Several different modalities are available for ureteral stone fragmentation. From them pneumatic and holmium: yttrium-aluminum-garnet (Ho: YAG) lithotripsy have supportive outcomes. In this study we studied 250 subjects who had ureteroscopic pneumatic lithotripsy (PL) or laser lithotripsy (LL).

Urinary stone ablation with a thulium fibre laser: a rate-of-completion evaluation

open access: yesВестник урологии, 2023
Introduction. The main disadvantage of using the rate of ablation of urinary stones as a parameter of thulium lithotripsy is the dependence of this parameter on the energy and frequency of laser pulses.

Non-spherical collapse of an air bubble subjected to a lithotripter pulse [PDF]

open access: yes, 2008
In order to better understand the contribution of bubble collapse to stone comminution in shockwave lithotripsy, the shockinduced and Rayleigh collapse of a spherical air bubble is investigated using numerical simulations, and the free-field collapse ...

Addition of Sodium Bicarbonate to Irrigation Solution May Assist in Dissolution of Uric Acid Fragments During Ureteroscopy [PDF]

open access: yes, 2018
Introduction: We hypothesized that adding sodium bicarbonate (bicarb) to normal saline (NS) irrigation during ureteroscopy in patients with uric acid (UA) nephrolithiasis may assist in dissolving small stone fragments produced during laser lithotripsy ...

Bubble Dynamics in Laser Lithotripsy [PDF]

open access: yesJournal of Physics: Conference Series, 2015
Laser lithotripsy is a medical procedure for fragmentation of urinary stones with a fiber guided laser pulse of several hundred microseconds long. Using high-speed photography, we present an in-vitro study of bubble dynamics and stone motion induced by Ho:YAG laser lithotripsy.

Numerical simulations of non-spherical bubble collapse [PDF]

open access: yes, 2009
A high-order accurate shock- and interface-capturing scheme is used to simulate the collapse of a gas bubble in water. In order to better understand the damage caused by collapsing bubbles, the dynamics of the shock-induced and Rayleigh collapse of a ...

Thermal effect of holmium laser during ureteroscopic lithotripsy

open access: yesBMC Urology, 2020
Background Holmium laser lithotripsy is the most common technique for the management of ureteral stone. Studies founded that holmium laser firing can produce heat which will cause thermal injury towards ureter.

Silica hollow core microstructured fibres for mid-infrared surgical applications [PDF]

open access: yes, 2013
In this paper two silica hollow core microstructured fibres (Negative Curvature Fibre and Photonic Bandgap Fibre) are presented with attenuations of 0.06 dB/m and 1.1 dB/m at 2.94 μm wavelengths, respectively.
