[Perioperative and early postoperative results of photoselective vaporization of the prostate using fiber 4090 (providing 120 watts) versus fiber MOXY (providing 180 watts)].

INTRODUCTION Photoselective vaporisation of the prostate (PVP) is a surgical alternative to transurethral resection of the prostate (TURP). The goal of this study was to compare the new AMS MOXY fiber which provide 180 watts power to the 4090 fiber 120 watts power source currently used in benign prostatic hyperplasia. The assessment criteria were peroperative and early postoperative data. METHOD This study was a monocentric prospective trial comparing two parallel groups of treatment: prostatic vaporisation with MOXY fiber (180 watts) against 4090 fiber (120 watts) in patients operated by an experienced surgeon. The urinary catheter was removed the day after the intervention and the patient was allowed to quit after a clinical examination. All the patients had a routine consultation at 1 month: clinical examination, max flow rate, biological results and results of autoquestionnaires. RESULTS This study included 50 patients. The two groups were similar at the inclusion: age, urinary catheter, and prostate volume. The operative data show a decrease of vaporization duration (29 minutes versus 36 minutes, P=0.009) with an energy delivered increased (281 kJoules versus 223 kJoules, P=0.036) and with similar postoperative data: duration of urinary catheterization (3.8 days versus 3.6 days, P=0.908), length of stay (1.6 days versus 1.8 days, P=0.371). The 1-month results were similar between the two groups. CONCLUSION The new fiber AMS 180 watts ROXY offer similar postoperative data to the 4090 fiber with improved operative duration and energy delivered.
