Abstract

Optical fiber systems with lateral emission of laser radiation are currently used for laser treatment of benign prostatic hyperplasia (BPH). They can be classified in reflective or refractive systems in which a mirror or a prism, respectively, is connected to the fiber tip. Both systems are disposable making the cost of treatment too high. An alternative solution for refractive systems is the prismatic cut of the fiber tip. A side fiber of this type was conceived at the Department of Chemical Physics of the University of Venice and then patented. An Olympus 27ch transurethral resectoscope was also modified for use with our side fiber as well as with the resecting blade. Our modified resectoscope with a Nd-YAG laser has been clinically used for the laser treatment of BPH (6 cases), as well as in high risk patients with bulky bleeding bladder tumors (4 cases), and in transitional tumors of the prostate infiltrating the parenchyma (2 cases). Laser treatment with our resectoscope resembles traditional endoscopic treatment, guarantees the precision of fiber tip translation, and permits combined treatments with laser and traditional blade.
