Exclusion Criteria:

• Any condition or history of illness or surgery that, in the opinion of the investigator and/or the Sponsor, might confound the results of the study or pose additional risks to the patient.

• Patients with a history of urethral stricture disease
• Patients with a history of acute urinary retention
• Patients who are currently (within 10 days before the treatment procedure) receiving any medications having potential photosensitizing effects (e.g. tetracyclines, sulfonamides, phenothiazines, sulfonylurea hypoglycemic agents, thiazide diuretics and griseofulvin)
• Patients who are currently receiving anticoagulant drugs (within 10 days before the treatment procedure) (e.g.: coumadin, warfarin)
• Patient who stopped long term treatment of acetylsalicylic acid (aspirin) or other anti platelets agents within 10 days prior to the treatment procedure;
• Patient suspected of Disseminated Intravascular Coagulation (DIC) as defined by the presence of three out of the five following criteria: platelets decrease, increase of PT, increase of aPTT, fibrinogen decrease, D-Dimer increase; from the normal laboratory ranges;
