- Abstract
Thulium lasers operate at wavelengths between1940-2013 nm either in a continuous wave or in a pulsed mode, which enables smooth incisions with fast vaporization or effective laser lithotripsy for urolithiasis. Thulium laser enucleation is a minimally invasive and size-independent treatment for benign prostatic hyperplasia (BPH) with excellent long-term results. Since its introduction, several modifications in the technology and surgical techniques have been proposed such as vaporesection, vaporization and enucleation with regard to BPH treatment. Recent developments in the thulium laser technology include the introduction of a super pulsed thulium fiberlaser. This technique delivers the laser energy through anactive fiber with an absorption maximum in water at awavelength of 1940 μm. Preclinical studies showed asignificantly higher stone fragmentation rate in differentex vivo models compared to the Ho:YAG laser. Another innovative thulium laser that works, as a hybrid laser has yet not been tested clinically, however, will soon be introduced. With the introduction of both new thulium lasers as novel devices, the armamentarium in the field of endourology for lithotripsy and enucleation increases. We here present different thulium lasers and surgical techniques that are possible to perform with each device including the reasons and advantages of each modification.
