Standardization of 532 nm Laser Terminology for Surgery in Benign Prostatic Hyperplasia (BPH): A Systematic Review
摘要： Introduction: The use of GreenLight? laser technology to remove the prostatic transitional zone (TZ) transurethrally has grown considerably in recent years, and with it an increase in the number of terms that are used to describe similar techniques. Varying terminology complicates literature analysis and publication, which can cause confusion when performing reviews of the literature. It has become necessary to simplify and standardize terminology used to describe transurethral prostate debulking procedures using the 532 nm laser in order to simplify communication on these techniques. Materials and Methods: We conducted a search on September 17th, 2019 in the following databases: Ovid MEDLINE?; Ovid EMBASE; and PubMed. Results: Of the 1115 unique records found in our database search, a total of 27 articles were selected for inclusion. Of the 16 search terms used, we found that 4 terms could be used to describe the fundamental technique associated with each search term. These terms include “vaporization”, “vaporesection”, “vapoenucleation”, and “enucleation”. Conclusions: Standardizing terminology leads to an efficient consolidation of terms based on the above outcomes. This will streamline the literature search process for future publications and facilitate comparison of varying techniques.

Dependence of laser-induced tissue ablation on optical fiber movements for laser prostatectomy
摘要： Purpose The aim of the current study was to identify the efficient fiber movements for 532-nm laser prostatectomy. Materials and methods 532-nm Lithium triborate (LBO) laser light was tested on 120 kidney tissues at three different translational speeds (TS 1, 2, and 4 mm/s) and four different rotational speeds (RS 0.5, 1.0, 1.6, and 2.1 rad/s). The applied power was 120 W at a 2-mm working distance and 60° sweeping angle. Ablation rate and dimensions of resulting ablation craters were measured. Results Slower TSs and RSs created deeper and wider ablation craters with thinner coagulation, leading to more efficient ablation performance. Maximal ablation rate was achieved at a TS of 2 mm/s and RSs of 0.5 and 1.0 rad/s. An RS of 0.5 rad/s accompanied surface carbonization for all the TSs. Irrespective of TS, ablation rate became saturated at faster RSs than 1.0 rad/s. Faster TSs or RSs reduced tissue ablation, but increased thermal coagulation due to a shorter interaction time. Conclusions Optimal ablation efficiency occurred at a TS of 2 mm/s and a RS of 1.0 rad/s with a thin coagulation of around 1.0 mm and no or minimal carbonization. Further studies will validate the current findings with prostate tissue and high-power levels for laser prostatectomy.
