Depending on various laser parameters and tissue characteristics, we can achieve different effects, including specific distribution of light and heat, chemical reaction, material ablation, ionization or shockwaves. Provided that, there are numerous medical applications of lasers such as biomodulation, photodynamic therapy (allows for fluorescent imaging of tumors located in the urinary tract and performance of more accurate biopsies), coagulation, vaporization (e.g. of prostate neoplasia), fusion, ablation, disruption and fragmentation (used for ureteric and kidney stone management). 
Urology is a highly demanding, challenging and dynamically developing field of medicine, hence it is paramount that urologists rely on adaptable and modifiable lasers. Different clinical scenarios usually require easily adjustable device settings such as pulse energies, pulse lengths and emitted frequencies. However, it should be highlighted that laser systems can cause serious complications and damage if used improperly. Therefore a laser system has to be intuitively modifiable according to the intended procedure.
Don't forget that light could be dangerous - use the technology in an appropriate way. Increase your awareness by listening to an excellent explanation of laser technology. Click here to watch the webinar by Prof. Oliver Traxer
