Paper Abstract

Introduction: Laser ablation of the prostatic tissue or laser prostatectomy, is used as an alternative method to traditional endoscopic resection of the prostate. The usual side-firing Nd:YAG laser fiber for the treatment of obstructive symptoms has operational difficulties, a high cost and often poor early results. Materials: We describe the laser coagulation of the prostate using a 600-um bare fiber inserted in a modified Albarran bridge which included at the tip, a new gold-plated deflectable reflector. The complete device passes through a 21Fr.rigid cysto- urethroscope. The system and the fiber can be used for several dozen treatments. The dosimetry was 2000 J per 1 cc of prostatic tissue. Methods: VLAP using the prostascope was performed on more than 70 men in one institution, and 150 in a second one, for obstructive symptoms due to benign prostatic hyperplasia. The parameter included AUA symptom score, flow rate, residual volume and complications. Data were obtained preoperatively and 1, 3, 6 and 12 months after treatment. Discussion: According to our data VLAP with this system is a save, minimal invasive and effective treatment. Results are comparable to other non-contact laser devices. As the gold-plated reflector is inexpensive and the standard bare fiber can be used repeatedly, the cost is less than of an usual side-firing laser fiber.
