ABSTRACT
PURPOSE:
To identify laser settings and limits applied by experts during laser vaporization (vapBT) and laser en-bloc resection of bladder tumors (ERBT) and to identify preventive measures to reduce complications.METHODS:
After a focused literature search to identify relevant questions, we conducted a survey (57 questions) which was sent to laser experts. The expert selection was based on clinical experience and scientific contribution. Participants were asked for used laser types, typical laser settings during specific scenarios, and preventive measures applied during surgery. Settings for a maximum of 2 different lasers for each scenario were possible. Responses and settings were compared among the reported laser types.RESULTS:
Twenty-three of 29 (79.3%) invited experts completed the survey. Thulium fiber laser (TFL) is the most common laser (57%), followed by HolmiumYttrium-Aluminium-Garnet (HoYAG) (48%), continuous wave (cw) ThuliumYttrium-Aluminium-Garnet (TmYAG) (26%), and pulsed TmYAG (13%). Experts prefer ERBT (91.3%) to vapBT (8.7%); however, relevant limitations such as tumor size, number, and anatomical tumor location exist. Laser settings were generally comparable; however, we could find significant differences between the laser sources for lateral wall ERBT (p = 0.028) and standard ERBT (p = 0.033), with cwTmYAG and pulsed TmYAG being operated in higher power modes when compared to TFL and HoYAG. Experts prefer long pulse modes for HoYAG and short pulse modes for TFL lasers.CONCLUSION:
TFL seems to have replaced HoYAG and TmYAG. Most laser settings do not differ significantly among laser sources. For experts, continuous flow irrigation is the most commonly applied measure to reduce complications.Palavras-chave
