NCT03131544

Brief Summary

Over 100,000 BPH procedures are performed annually in the US. The purpose of this study is to evaluate the effectiveness of performing MRI guided transrectal laser ablation using a 980 nm laser (VisualaseTM by Medtronic, Inc., a Minnesota, U.S.A. company) to treat benign prostatic hypertrophy (BPH). The laser system will be used to necrotize urological soft tissue within the prostate under MRI guidance. This will be a single center, single arm prospective trial with an anticipated enrollment of 10 men. Patients who elect this treatment option and choose to be part of the study will be enrolled consecutively.

Outcome Measures

Primary Outcomes (17)

  • International Prostate Symptom Score (IPSS) Change

    The IPSS survey rates lower urinary tract symptom severity from 0 (none) to 35 (severe).

    From baseline to 2 months

  • International Prostate Symptom Score (IPSS) Quality of Life (QoL) Question Change

    The IPSS QoL question asks patients to rate how they would feel if they were to spend the rest of their lives with their urinary condition just the way it is now, from 0 ("delighted") to 6 ("terrible")

    From baseline to 2 months

  • BPH Impact Index Change

    This is another survey which rates lower urinary tract symptoms from 0 (none) to 13 (severe)

    From baseline to 2 months

  • Sexual Health Inventory of Men (SHIM) Score Change

    This survey rates erectile function from 0 (no function) to 25 (full function)

    From baseline to 2 months

  • Number of Adverse Events

    We asked patients to self-report adverse events.

    Continuous until completion of the study at 2 years

  • International Prostate Symptom Score (IPSS) Change

    The IPSS survey rates lower urinary tract symptom severity from 0 (none) to 35 (severe).
