Pneumatic Lithotripsy Versus Laser Lithotripsy for Ureteral Stones
Journal 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).

Cholangioscopy-guided lithotripsy in the treatment of difficult bile ducts stones – Bulgarian and Egyptian experience [PDF]
Folia Medica, 2023 Introduction: Up to 10% of bile duct stones are deemed ‘difficult’ because they cannot be extracted using standard endoscopic techniques. In these situations, cholangioscopy allows for stone fragmentation under direct visual control.

Thermal effect of holmium laser during ureteroscopic lithotripsy
BMC 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.

Bubble Dynamics in Laser Lithotripsy [PDF]
Journal 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.

A method for reducing thermal injury during the ureteroscopic holmium laser lithotripsy
Asian Journal of Urology, 2023 Objective: Many studies have demonstrated the heat effect from the holmium laser lithotripsy can cause persistent thermal injury to the ureter. The purpose of this study was to elucidate the use of a modified ureteral catheter with appropriate firing and
