    Safety, efficacy and outcomes of the new GreenLight XPS 180W laser system compared to the GreenLight HPS 120W system for the treatment of benign prostatic hyperplasia in a prospective nonrandomized single-centre study

    Introduction: We compare and evaluate the safety, efficacy, and short-term outcomes of the new GreenLight XPS 180W (GL-XPS) laser system with the former generation GreenLight HPS 120W (GL-HPS) system for the treatment of benign prostatic hyperplasia (BPH) in a prospective nonrandomized single-centre study. Methods: From May 2012 to June 2013, 161 consecutive patients with lower urinary tract symptoms secondary to BPH were included: 88 patients were treated with the GL-HPS system and 73 were treated with the GL-XPS system. The perioperative variables International Prostate Symptom Score (IPSS), quality of life (QOL), and maximum flow rate (Qmax) were recorded at baseline, at one month and 6 months. Serum prostate-specific antigen (PSA) was assessed at baseline. Results: The mean age was 70.2 years in the GL-HPS group and 68.6 years in the GL-XPS group. Prostate volumes were 62.3 mL and 61.3 mL, respectively. Both groups showed significant postoperative improvement in the IPSS, QOL, Qmax variables compared to baseline levels. There were no significant differences in improvement in IPSS and QOL between groups. However, both operating and catheterization times were shorter in patients in the GL-XPS group. The overall postoperative complication rate was similar in both groups. Conclusion: Both GreenLight systems provide safe, effective tissue vaporization with significant clinical relief of BPH obstruction. The GL-XPS system appears more favourable with regard to reduced operating and hospitalization time, suggesting more cost-effective and efficient tissue removal.

    Safety and efficacy of photoselective vaporization of the prostate using the 180-W GreenLight XPS laser system in patients taking oral anticoagulants
    (SAGE PUBLICATIONS LTD, 2018-01-01) Eken, Alper; Soyupak, Bulent
    Objective To evaluate the safety and efficacy of the 180-W GreenLight XPS laser system for the treatment of benign prostatic hyperplasia in patients taking oral anticoagulants. Methods All consecutive patients admitted for lower urinary tract symptoms associated with benign prostatic hyperplasia from November 2012 to October 2016 and who underwent photoselective vaporization of the prostate with the 180-W GreenLight XPS laser were included in the study. The perioperative outcomes examined were the operating time, laser time, energy usage, and duration of postoperative catheterization. Functional parameters (International Prostate Symptom Score, maximum urinary flow rate, and post-void residual urine volume), prostate volume, and serum prostate-specific antigen concentration were examined at baseline and 3 months. Perioperative complications, if any, were noted. Results All functional parameters (International Prostate Symptom Score, maximum urinary flow rate, and post-void residual urine volume) significantly improved from baseline to 3 months. A small number of patients experienced at least one minor adverse event. There was no difference in the rate of adverse events between patients who were and were not taking anticoagulants. Conclusions Photoselective vaporization with a 180-W laser is an efficacious and safe treatment for benign prostatic hyperplasia, even in patients taking anticoagulant medications.
