OBJECTIVE: Partial nephrectomy is a technique that requires extensive manipulation and control of the renal vessels. In this paper we will evaluate the contribution of Revolix® laser to the minimally invasive and nephron sparing renal surgery over the years 2005-2008.METHODS: We have used the Revolix® laser (Thulium), with a wavelength of 2013 nm in the infrared (invisible) spectrum, which can work in a continue or pulsed manner. Its chromophore target is water. Two different techniques may be employed: vaporization (side firing fiber) or vaporresection (frontal fiber). In all cases we used the frontal fiber (rigifib, flexifib and percufib), for vaporresection between 12 and 15 watts.
