Objective: To evaluate the noise levels of Holmium:YAG (Ho:YAG), Thulium Fiber (TFL), and pulsed Thulium:YAG (p-Tm:YAG) lasers across various settings, focusing on compliance with safety thresholds and potential impact on communication in the operating room (OR).

Materials And Methods: Noise measurements were taken in an empty OR using sound meters placed 1 m from the laser source. Ambient noise, standby, ready, and lasering modes at three settings (0.2 J-50 Hz, 0.5 J-20 Hz, and 1 J-10 Hz) were measured. Background noise was adjusted logarithmically, and sound emissions were weighted on dBA. Eleven laser models across Ho:YAG, TFL, and p-Tm:YAG systems were analyzed using descriptive and inferential statistics.

Results: Noise levels varied significantly by system and setting. All lasers produced <55dBA during standby/ready modes. During lasering, the Rocamed MH01 (Ho:YAG), RevoLix (Tm:YAG), and IPG Urolase PRO (TFL) were the quietest. The Quanta Cyber Magneto (Ho:YAG), Dornier Thulio (Tm:YAG), and EMS Laserclast (TFL) reached the highest noise levels, up to 66.06dBA. All lasers complied with NIOSH (85dBA) and OSHA (90dBA) limits, though several exceeded the 55dBA threshold for high-concentration tasks.

Conclusion: Endourological lasers produce <55dBA in standby/ready modes but may exceed this during lasering, potentially impacting communication and focus in the OR. While occupational noise risks are minimal, attention to noise emissions is crucial for optimizing surgical team performance. Future studies should explore noise impact on surgical outcomes.

Exploring the optimal parameter settings of a thulium fiber laser during soft tissue resection.

There is a lack of clinical consensus on the parameter settings of the pulsed-wave thulium fiber laser for soft tissue resection. The aim of this study was to explore the optimal parameter settings of the pulsed-wave thulium fiber laser for soft tissue resection, with a view to providing a reference for future clinical applications. Two different thulium fiber lasers, prototype thulium fiber lasers and Urolase, were used to explore the optimal parameters of thulium fiber laser for soft tissue cutting by evaluating the depth of tissue vaporization and depth of thermal damage in an isolated pig kidney model, and then the optimal parameters of in vitro screening were statistically validated by operation time, coagulation time, intraoperative hemorrhage, smoke level, and depth of thermal damage in an in vivo model using rabbit kidney.

Background: The direct in-scope suction (DISS) involves a two-way adaptor mounted on a scope to aspirate and irrigate the pelvicalyceal system during flexible ureteroscopy. While integrated suction single-use scopes manage small dust particles effectively, they cannot remove particles >250 µm and are limited by single use.

Objectives: To evaluate perioperative outcomes of the GLITZ system, a lightweight suction accessory for flexible ureteroscopes, facilitating laser lithotripsy with integrated aspiration.

Prior laser studies have demonstrated that as the temperature of a medium increases, the amount of energy delivered to the target increases. We sought to investigate the role of irrigation fluid temperature on Thulium fiber laser (TFL) urolith ablation. 360 calculi were divided in vitro according to chemical composition: calcium oxalate monohydrate (COM), cystine (CYS), struvite (STR), calcium phosphate (CAP), uric acid (UA), and calcium oxalate dihydrate (COD).
