The thulium fiber laser (TFL) is currently being studied as an alternative to the conventional holmium:YAG (Ho:YAG) laser for lithotripsy. The diode-pumped TFL may be electronically modulated to operate with variable parameters (e.g., pulse rate, pulse duration, and duty cycle) for studying the influence of pulse train mode on stone ablation rates. The TFL under study was operated at 1908 nm, 3...

Sialolithiasis is the presence of stones in the ducts of the salivary glands. Most episodes are unique, and 60-80% are located exclusively in the main excretory duct. The main clinical manifestations are swelling and pain typically before, during or after meals that decreases if the obstruction is not complete. The highest prevalence of lithiasis is in the submandibular gland -87%-, whose secre...

Abstract Background Treatment of broncholithiasis is complex, especially in the case a large or transbronchial broncholith. Holmium-yttrium aluminum garnet (Ho:YAG) laser lithotripsy may be useful treatment broncholithiasis; however, as it not yet common practice, optimal parameters are unknown. Methods We performed single-center retrospective analysis clinical data 13 patients who underwent Ho...

Aims: To compare the outcome after flexible ureteroscopic (FURS) laser lithotripsy and extracorporeal shock wave (ESWL) for management of patients with upper ureteral calculi up to 2 cm.
 Study Design: A prospective randomized comparative study.
 Place Duration Study: Tanta Urology Department, University in Tanta, Egypt between October 2018 2021.
 Methodology: We included 95 (62 ...

BACKGROUND AND AIMS To compare extracorporeal shock wave lithotripsy (ESWL) and laser induced shock wave lithotripsy (LISL) of retained bile duct stones to stone free rate, number of therapeutic sessions, and costs. PATIENTS Thirty four patients were randomly assigned to either ESWL or LISL therapy. The main reasons for failure of standard endoscopy were due to stone impaction (n = 12), bilia...
