Vardenafil in Greenlight(TM) laser surgery of Benign Prostate Hypertrophy

Trial purpose

The greenlight laser has an absorption maximum which is exactly the same as for hemoglobin. In the presence of hemoglobin, its application causes vaporization of the tissue and this effect depends on the concentration of hemoglobin in the respective tissue. Therefore, increase of blood-flow in the tissue (here: prostate gland) should exert better efficacy of the laser application and consequently shortening of the required duration of laser application.
