INTRODUCTION: Intending to overcome transurethral resection of the prostate (TURP) in terms of safety maintaining its efficacy profile, have led to the introduction of minimally invasive laser therapies to treat men with lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO), each one with its unique properties. The aim of this review was to analyze and summarize all the existing data regarding the 180 W Xcelerated Performance System (XPS) photoselective vaporization of the prostate (PVP).
EVIDENCE ACQUISITION: A systematic review was conducted: 45 papers were identified. After excluding those not in English language, duplicates, case reports and “expert opinion” papers, 39 articles were reviewed.
EVIDENCE SYNTHESIS: The XPS emits a 532 nm wavelength generated using a lithium triborate crystal in a quasi-continuous mode through a 750 µm, continuously saline-cooled, metal capped MoXy™ fibre. This system has overcome the previous model in terms of surgical and functional outcomes. Although several techniques have been proposed, the IGLU modular one is considered the standard approach for 180 W PVP. Authors estimated the need for at least 120 cases to reach an expert level of competence. The GOLIATH Study has proven the non-inferiority of XPS PVP to TURP. The procedure is safe and effective also in large glands but long operative times still represent an issue. Considering the total average costs, XPS PVP provides and advantage over TURP. International guidelines consider PVP the best option to manage patients receiving anticoagulants or with a high cardiovascular risk.
CONCLUSIONS: PVP should be considered an adult technique and, as suggested by the EAU Guidelines, is the best surgical option to manage patients receiving anticoagulant medication or with a high cardiovascular risk. The development of new surgical techniques such as APV, PEBE and seminal spearing approaches could represent a possibility to further implement the XPS indications. Dedicated unit could improve the management LUTS/BPO men.
