    IT WAS REPORTED TO BOSTON SCIENTIFIC VIA AN ARTICLE PUBLISHED IN LASERS IN MEDICAL SCIENCE THAT A STUDY WAS CONDUCTED TO COMPARE AND ANALYZE THE EFFICACY AND SAFETY OF GREENLIGHT PHOTOSELECTIVE VAPORIZATION OF THE PROSTATE (PVP) PROCEDURES IN ELDERLY HIGH-RISK BENIGN PROSTATE HYPERPLASIA (BPH) PATIENTS. THE STUDY COMPARED THE RESULTS OF PATIENTS WHO UNDERWENT 120 W GREENLIGHT HPS PROCEDURES TO THOSE WHO UNDERWENT 180 W GREENLIGHT XPS PROCEDURES. A TOTAL OF 84 PATIENTS UNDERWENT THE PVP PROCEDURE BETWEEN DECEMBER 2013 AND FEBRUARY 2016. OF THESE PATIENTS, 40 PATIENTS UNDERWENT THE 120 W PROCEDURE AND 44 UNDERWENT THE 180 W PROCEDURE. ALL PATIENTS HAD A PROSTATE GLAND VOLUME OVER 80 ML AND HAD AT LEAST ONE INTRAOPERATIVE COMORBIDITY: HYPERTENSION, DIABETES MELLITUS, NEW YORK HEART ASSOCIATION (NYHA) II, OR COMBINED. ALL PROCEDURES WERE CONDUCTED WITH THE PATIENTS UNDER GENERAL ANESTHESIA. A STORZ 22F CONTINUOUS FLOW CYSTOSCOPE WITH A LASER BRIDGE WAS USED, THE FIBER WAS INSERTED THROUGH THE CONTINUOUS FLOW CYSTOSCOPE WITH A SEPARATE CHANNEL, AND STERILE WATER WAS USED AS AN IRRIGATION FLUID. ALL PROCEDURES WERE COMPLETED SUCCESSFULLY WITHOUT PATIENT COMPLICATIONS. FOLLOW-UP VISITS WERE THEN CONDUCTED AT 4 WEEKS, 6 MONTHS, AND 1 YEAR POST-PROCEDURE. PATIENTS IN THE 120 W GROUP EXPERIENCED THE FOLLOWING COMPLICATIONS: 3 PATIENTS HAD FEVER, 2 PATIENTS EXPERIENCED BLEEDING, 7 PATIENTS EXPERIENCED URGE INCONTINENCE, 1 PATIENT EXPERIENCED URETHROSTENOSIS, 1 PATIENT EXPERIENCED BLADDER NECK CONTRACTURE, AND 1 PATIENT REQUIRED RE-CATHETERIZATION. PATIENTS IN THE 180 W GROUP EXPERIENCED THE FOLLOWING COMPLICATIONS: 2 PATIENTS HAD FEVER, 2 PATIENTS EXPERIENCED BLEEDING, 10 PATIENTS EXPERIENCED URGE INCONTINENCE, 2 PATIENTS EXPERIENCED BLADDER NECK CONTRACTURE, AND 2 PATIENTS REQUIRED RE-CATHETERIZATION. MOST OF THE PATIENTS WHO EXPERIENCED URGE INCONTINENCE FROM BOTH GROUPS SHOWED RECOVERY WITHIN 6 MONTHS POST-PROCEDURE. ONLY ONE OF THE PATIENTS FROM THE 180 W GROUP REPORTED EXPERIENCING URGE INCONTINENCE UP UNTIL THE 1 YEAR VISIT POST-PROCEDURE. OVERALL, IT WAS NOTED THAT THE OPERATION TIME AND CATHETERIZATION TIME WAS SIGNIFICANTLY SHORTER FOR PATIENTS WHO UNDERWENT THE 180 W PROCEDURE COMPARED TO THOSE WHO UNDERWENT THE 120 W PROCEDURE. PATIENTS FROM BOTH GROUPS HAVE SHOW SIGNIFICANT IMPROVEMENTS IN THE INTERNATIONAL PROSTATE SYMPTOM SCORES (IPSS), QUALITY OF LIFE (QOL) SCORES, MAXIMUM FLOW RATE (QMAX), AND RESIDUAL URINE VOLUME (RUV). THIS REPORT IS FOR THE PATIENTS WHO UNDERWENT THE 180W PROCEDURE.
