    Background: Photoselective vaporisation of the prostate has evolved from the GreenLight 80-W KTP powered laser to the latest 180-W XPS laser involving a MoXy fibre.

    Objective: Evaluate the prevalence of perioperative complications and short-term outcome for the first time with the XPS laser in men with lower urinary tract symptoms (LUTS) due to benign prostatic enlargement (BPE).

    Design, setting, and participants: Prospective data were collected from consecutive patients at seven centres worldwide during June 2010 and March 2011. Indication for surgery was based on the European Association of Urology and the American Urological Association guidelines. Patients receiving anticoagulants or those with retention were included and analysed separately.

    Intervention: 180-W XPS GreenLight laser prostatectomy using the MoXy fibre.

    Measurements: Standard parameters associated with transurethral prostate surgery and perioperative prevalence of surgery-associated problems or complications were documented.

    Results and limitations: A total of 201 patients were included in the study. Mean follow-up was 5.8 mo (standard deviation [SD]: 2.8; range: 1-12 mo). A quarter of the patients had a prostate volume >= 80 ml. For prostates between 51 and 60 ml, a mean of 300 kJ (SD: 112) of energy was applied (lasing time: 35.0 min; SD: 15). Statistically significant improvements were noted in all key parameters postoperatively. The prevalence of perioperative complications was low. Limitations of the study are short duration of follow-up and limited number of available patients for the functional follow-up.

    Conclusions: The 180-W GreenLight XPS laser is a new effective treatment option with a low prevalence of perioperative complications for patients suffering from LUTS due to BPE.
