Recently 2 μm continuous-wave (CW) lasers were introduced for endoscopic and open surgery. The 2 μm wavelength is predominantly absorbed by water and enables effective cutting and ablation of tissue with tissue effect comparable to the CO 2 laser. The Revolix junior 15 W and the Revolix duo (20W Holmium and 70W 2.0 μm CW LISA laser, Germany), both 2 μm CW lasers, were used for various urological applications. The clinical treatment strategies were studied in an experimental setup to find the optimal laser settings in regard to thermal and mechanical effects for optimal and safe clinical application. Various clinical procedures have been performed. In a non contact mode, the 2 μm CW laser enables controlled ablation with sufficient superficial coagulation to ensure haemostasis during surgery. In contact mode, the 2 μm CW laser is more efficient in tissue cutting and ablation compared to the Nd:YAG laser. The 2 μm CW laser has shown to be a versatile instrument for effective treatment at several urological indications. More patients and long term follow up are needed to prove the clinical significance compared to other treatment modalities.
