Brief Summary:
Single-arm, interventional pivotal clinical trial collecting patient data from use of the AQUABEAM System, a personalized image-guided waterjet resection system that utilizes a high-velocity saline stream to resect and remove prostate tissue in males suffering from Lower Urinary Tract Symptoms (LUTS) due to Benign Prostatic Hyperplasia (BPH).The primary endpoints for safety and effectiveness will be measured at 3 months post-treatment. All treated subjects will be followed out to 12 months to collect long-term clinical data.
