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

Вестник 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.

Intrarenal arteriovenous malformation following flexible ureterorenoscopy and holmium laser stone fragmentation: report of a case

BMC Urology, 2019
Background Flexible ureterorenoscopy (FURS) and holmium laser lithotripsy is currently considered as one of the treatment options for large renal calculi. It has been shown to be safer than percutaneous nephrolithotomy.

comparative study to evaluate safety and efficacy of pneumatic versus laser lithotripsy in pediatric mini-percutaneous nephrolithotripsy

Minia Journal of Medical Research
Introduction In an effort to lessen the risk of complications during surgery, mini-PCNL—a diminutive version of the traditional PCNL—was developed. When planning a standard or mini-PCNL, the lithotripter is just as crucial as the operating duration ...

Utility of Direct Peroral Cholangioscopy Using a Multibending Ultraslim Endoscope for Difficult Common Bile Duct Stones

Gut and Liver, 2022
Background/Aims: Treatment options for difficult bile duct stones are limited. Direct peroral cholangioscopy (POC)-guided lithotripsy may be an option. A newly developed multibending (MB) ultraslim endoscope has several structural features optimized for ...

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...
