Interventional
Description of intervention(s) / exposure
Treatment: Devices - REZUM
Treatment: Drugs - alpha blocker and 5-alpha reductase inhibitor

Active comparator: REZUM - Subjects randomized to receive the REZUM treatment will receive standardized treatment, following the Instruction for Use (IFU). The REZUM System is intended to relieve symptoms, obstructions, and reduce prostate tissue associated with benign prostatic hyperplasia (BPH). It is indicated for men with a prostate volume = 30 ml. The REZUM System is also indicated for treatment of prostate with hyperplasia of the central zone and/or a median lobe.

1:1 randomization will occur via the electronic data capture (EDC) system.

Active comparator: Dual Drug Therapy - Subjects assigned to dual drug therapy will be treated with the local formulary preferred choice of commercially available urinary selective alpha blocker and 5-alpha reductase inhibitor. This arm will therefore represent local standard of care.
