Prostatic Vapor Ablation with Rezum
Device: Prostatic Vapor Ablation
Rezūm uses the stored thermal energy in water vapor (steam) to treat the extra prostate tissue that is causing symptoms such as frequency, urgency, irregular flow, weak stream, straining and getting up at night to urinate.
Inside a hand-held device, radiofrequency energy is applied to a few drops of water to create vapor (steam). The water vapor is injected into the prostate tissue that is blocking the flow of urine from the bladder, where it immediately turns back to water, releasing the energy stored in the vapor into the cell membranes. At this point, the cells are gently and immediately damaged, causing cell death. Over time, the body absorbs the treated tissue through its natural healing response.
- Number of Participants With ≥ 30% Improvement in Symptoms as Measured by the International Prostate Symptom Score (IPSS) [ Time Frame: 6 Months ]The proportion of the intent-to-treat (ITT) analysis population that responds to the Rezum therapy is reported. A responder is defined as a subject who has an improvement in International Prostate Symptom Score (IPSS) > 30% from baseline to 6 months post-therapy. IPSS scores range from 0 (no symptoms) to 35 (severe symptoms). Improvement in symptoms is shown by a reduction in score.
- Number of Participants With Post Procedure Device Related Serious Complications [ Time Frame: 6 Months ]Assess the composite rate of post procedure device related serious complications in treated subjects through 6 months follow-up.
- Number of Subjects With Device-related Retention Catheterizations [ Time Frame: 6 Month ]This safety endpoint will be to characterize the rate of post procedure device-related serious retention catheterizations at 6 months.
- Change in Lower Urinary Tract Symptoms as Assessed by the Absolute Change in IPSS Score From Baseline to Follow-up [ Time Frame: Baseline, 6 weeks, 3 months, 6 months, 1 year ]The change in IPSS from baseline to each follow-up visit was determined. IPSS scores range from 0 (no symptoms) to 35 (severe symptoms). Improvement in symptoms is shown by a reduction in score.
